Can you explain the answer of this question below:
Two different concepts, copyright infringement and plagiarism, are often confused for each other. Copyright infringement deals with the unauthorized use of copyright material and hence the violation of the rights of the copyright holder. Plagiarism, on the other hand, is concerned with false claims of authorship of ideas, works etc. that may not necessarily be protected under copyright. Moreover, even if a person gets the permission to use copyright material, it may still account for plagiarism if the person tries to falsely claim the authorship of the material.
 Which of the following must be true on the basis of the information given in the above argument?
  • A:
    Plagiarism may not always amount to copyright infringement but copyright infringement always amounts to plagiarism.
  • B:
    Any unauthorized use of material that has been protected under copyright will be considered plagiarism. 
  • C:
    Under certain conditions, use of copyright free material can still be considered plagiarism.
  • D:
    Even authorized use of copyright material amounts to plagiarism.
  • E:
    In a court of law, it is easier to prove a case of copyright infringement than a case of plagiarism.
The answer is C.

Which of the following must be true on the basis of the information given in the above argument?
 
Pre-Thinking
Conclusion Clarification
The question stem says that “Which of the following must be true on the basis of the information given in the above argument?” The question requires us to draw a conclusion based on statements in the passage. Please note that the conclusion must be based only on the information provided in the passage.
Pre-Thinking Approach
In order to see what can be concluded from the argument, we would need to observe all the facts given in the argument and see what must also be true if the information in the passage is true.
Let us combine a couple of pieces of information presented in the passage:
Plagiarism is concerned with false claims of authorship of ideas, works:
  1. protected under copyright
  2. not protected under copyright
  3. Even if a person gets the permission to use copyright material, it still accounts for plagiarism if the person tries to falsely claim the authorship of the material.
Conclusion: If a person tries to falsely claim the authorship of a non-copyrighted material, it still accounts for plagiarism.
With this understanding in mind, let’s take a look at the option statements.
Answer Choices
A
Plagiarism may not always amount to copyright infringement but copyright infringement always amounts to plagiarism.
Incorrect - No information given
While the passage tells us that plagiarism does not always amount to copyright infringement, it doesn’t tell us that copyright infringement always amounts to plagiarism.
B
Any unauthorized use of material that has been protected under copyright will be considered plagiarism. 
Incorrect - No information given
According to the passage, any unauthorized use of material that has been protected under copyright will be considered copyright infringement. It does not amount to plagiarism unless false authorship is claimed. 
C
Under certain conditions, use of copyright free material can still be considered plagiarism.
Correct
This matches our pre-thinking analysis and is the correct answer choice.
D
Even authorized use of copyright material amounts to plagiarism.
Incorrect - No information given
This can only happen in certain cases – when people falsely claim authorship.
E
In a court of law, it is easier to prove a case of copyright infringement than a case of plagiarism.
Incorrect - No information given
Comparison between ease of proving copyright infringement and plagiarism cannot be inferred since the passage does not even mention it.

When patients with clinical depression come to Royal Cornhill Mental Health Institute, they are first treated with psychotherapy and antidepressants. Only 40 percent respond to their first treatment. More than 20 percent of depressed people respond to no treatment at all.If the information given above is true, which of the following statements must be true?
  • a)
    At least 60% of the patients who do not respond to the first treatment respond to some other treatment.
  • b)
    At least 30% of the patients who do not respond to the first treatment do not respond to the subsequent treatments as well.
  • c)
    Of the 40% patients who respond to their first treatment, at least 50% also respond to some other treatment.
  • d)
    Of the people who respond to some treatment, the proportion that responds to the first medication is the lowest.
  • e)
    Of the 20% patients who responded to no treatment at all, at least 10% would have responded to some treatment had it not included the use of antidepressants.
Correct answer is option 'B'. Can you explain this answer?

In some scenarios, general arbitration can be pursued even if one of the parties is unwilling to get into the arbitration.
First line of the prompt says A party cannot be compelled to submit to general arbitration unless there is a contractual basis for concluding that the party agreed to do so. implying in some cases if there is a contract the second party can be compelled to come for an arbitration.

Researchers have discovered that a quick study of the hands — more specifically, the lengths of the index and ring fingers — can reveal a lot about a person’s personality and risk of disease. Of course, your fingers don’t actually control these issues; it’s closer to the other way around. 
Which of the following statements is best supported by the above information?
  • a)
    The larger the difference in the length of the index fingers and ring fingers, the clearer the understanding of the person’s personality that can be achieved through the study of hands.
  • b)
    The lengths of the ring and index fingers are expected to be different for people with different personalities.
  • c)
    It is difficult to ascertain through the study of hands the personality and disposition to disease of a person with almost no difference in the length in the length of index and ring fingers.
  • d)
    Other fingers, except the ring and index fingers, do not provide much information about a person’s personality and risk of disease.
  • e)
    A person’s personality and risk of disease is generally controlled by the length of the index and ring fingers.

Conclusion Clarification
N/ A
Pre-Thinking Approach
In order to see which statement can be best supported by the passage, we would need to observe all the facts given in the argument and see if the information in the passage is true, what must also be true.
Inferences: – From the above given information in the passage we can conclude the following:
  • Linkage #1 – (ref.  statement 1& 2 in the logical structure)
  • Conclusion – Different personalities and disease risks will affect the lengths of the index and ring fingers in different ways. 
With this pre-thinking in mind, let's take a look at the option statements.
Answer Choices
A
The larger the difference in the length of the index fingers and ring fingers, the clearer the understanding of the person’s personality that can be achieved through the study of hands.
Incorrect - No information given
The passage only mentions the lengths of the I&R fingers but we are not given any information to conclude on the difference in the length of the index and ring fingers. It could be the case that each finger refers to some personality traits or risks and individual length of a finger is studied to draw the information about the person. In this case, the difference in the length of fingers is of no relevance.
B
The lengths of the ring and index fingers are expected to be different for people with different personalities.
Correct
This option is written along the lines of our pre-thinking combination of linkage 1. Passage supports that for different personalities, these lengths are also expected to be different.
C
It is difficult to ascertain through the study of hands the personality and disposition to disease of a person with almost no difference in the length in the length of index and ring fingers.
Incorrect - No information given
The passage only mentions the lengths of the index and ring fingers, not the difference in lengths and the role played by it.
D
Other fingers, except the ring and index fingers, do not provide much information about a person’s personality and risk of disease.
Incorrect - No information given
We only know that the lengths of index and ring fingers can give us information about a person’s personality and risk of disease. We don’t know what role other fingers can play.
E
A person’s personality and risk of disease is generally controlled by the length of the index and ring fingers.
Incorrect - No information given
As we observed in logical structure, a person’s personality and risk of disease controls the lengths of the index and ring fingers and not the other way round.

IQ or intelligence quotient that deals with understanding information and EQ or emotional quotient that deals with understanding emotions are both key in assuring a person's happiness and ability to succeed. Although people with a high IQ are exceptionally brilliant at understanding information, when it comes to social interaction they usually have to work hard to understand others and to make themselves understood. Thus, a person with a high EQ is more likely to be happy and successful than a person with a high IQ. Which of the following must be true based on the information given above?
  • a)
    People with a high IQ are not aware of the importance of social interactions in determining their happiness and success.
  • b)
    People with a high IQ generally have a very low EQ.
  • c)
    A significant part of understanding people in social interaction does not deal with understanding information.
  • d)
    A person with a low EQ but a high IQ is less likely to be successful than a person with a low IQ and low EQ.
  • e)
    IQ and EQ are the only two important factors in determining a person’s happiness and ability to succeed.

The question stem says: “Which of the following must be true based on the information given above?” Therefore, the question requires us to draw an inference based on the statements in the passage. In order to see what can be inferred from the argument, we would need to observe all the facts given in the argument and see what must also be true if the information in the passage is true. Please note that the inference must be based only on the information provided in the passage.
Let us combine few pieces of information presented in the passage:
  1. People with a high IQ are exceptionally brilliant at understanding information.
  2. When it comes to social interaction they (people with a high IQ) usually have to work hard to understand others and to make themselves understood.
  3. A person with a high EQ is more likely to be happy and successful than a person with a high IQ.
Inference 1 (combining 1, 2 & 3): Ease of handling social interactions plays a more significant role than understanding information in the happiness and success of a person.
Inference 2 (combining 1 & 2): Ease of understanding information does not play a major role in social interactions.
With this understanding in mind, let's evaluate the option choices.
Answer Choices
A
People with a high IQ are not aware of the importance of social interactions in determining their happiness and success.
Incorrect - No information given
The passage says that people with high IQ find it difficult to handle social interactions. This does not in any way mean that people with a high IQ are not aware of the importance of social interactions.
B
People with a high IQ generally have a very low EQ.
Incorrect - No information given
The passage only compares a person with high IQ and a person with high EQ. This does not necessarily mean that if the IQ is high then the EQ would generally be very low.
C
A significant part of understanding people in social interaction does not deal with understanding information.
Correct
This statement is on the same lines as our pre-thinking inference no. 2.
D
A person with a low EQ but a high IQ is less likely to be successful than a person with a low IQ and low EQ.
Incorrect - No information given
In the comparison presented in the option, both scenarios talk about people with low EQ. Therefore, the option in effect compares a person with high IQ and a person with low IQ and says that the one with high IQ is less likely to be successful than the one with low IQ. This cannot be inferred.
E
IQ and EQ are the only two important factors in determining a person’s happiness and ability to succeed.
Incorrect - No information given
We know that IQ & EQ are important factors for determining happiness and ability to succeed. However, we do not know if they are the ONLY 2 important factors.

A party cannot be compelled to submit to general arbitration unless there is a contractual basis for concluding that the party agreed to do so. However, class arbitration is a specific kind of arbitration that changes the nature of general arbitration to such a degree that it cannot be presumed that parties consented to class arbitration simply by agreeing to submit their disputes to an arbitrator.Which of the following statements is best supported by the passage above?
  • a)
    Generally, class arbitration and general arbitration are used for different kinds of disputes.
  • b)
    A company cannot sign a contract with another company that allows it to pursue class arbitration even before opting for general arbitration.
  • c)
    In some scenarios, general arbitration can be pursued even if one of the parties is unwilling to get into the arbitration.
  • d)
    If the arbitrator decides so, then a company can be subjected to class arbitration because it agreed to settling the disputes through general arbitration.
  • e)
    Even if there is a contractual basis for class arbitration, a party cannot be compelled to enter in to it if it prefers to opt for general arbitration instead.

Argument Analysis
 
Pre-Thinking
Conclusion Clarification
N/A
Pre-Thinking Approach
The question requires us to find a statement which can be inferred from the passage. For that, we need to look at the given facts closely and come up with an inference that is either a combination of the two facts or a restatement of the given information in different words. Accordingly, from A party can’t be compelled for GA (reference: logical structure diagram above), we can infer that:
  1. A prior CB for GA is a must if one of the parties wishes to enforce GA.
Combining A party can’t be compelled for GA and CA changes the nature of GA(reference: logical structure diagram above), we can also infer that:
  1. A contract for GA could be used to enforce GA but not necessarily CA.
With this understanding in mind, let’s take a look at the option statements.
Answer Choices
A
Generally, class arbitration and general arbitration are used for different kinds of disputes.
Incorrect - No information given
The passage doesn’t provide any information regarding the kind of disputes where CA or GA is used.
B
A company cannot sign a contract with another company that allows it to pursue class arbitration even before opting for general arbitration.
Incorrect - No information given
The passage doesn’t provide any information regarding the order in which these contracts can be signed.
C
In some scenarios, general arbitration can be pursued even if one of the parties is unwilling to get into the arbitration.
Correct
This choice is written along the lines of our pre-thinking per Statement 1. Even if one of the parties is unwilling to get into arbitration but had signed a contract for the same, GA can be pursued.
D
If the arbitrator decides so, then a company can be subjected to class arbitration because it agreed to settling the disputes through general arbitration.
Incorrect - Against the given information
This option goes against CA changes the nature of GA (ref.: logical structure diagram) that states that agreement to GA can’t be taken as a basis for CA.
E
Even if there is a contractual basis for class arbitration, a party cannot be compelled to enter in to it if it prefers to opt for general arbitration instead.
Incorrect - No information given
The passage doesn’t provide any information regarding how preference of a party changes the situation.

Even though the terms taste aversion and taste avoidance are sometimes used interchangeably, there exists enough evidence to conclude that these two phenomena are likely not always related to each other. Research shows that taste aversion occurs when the consumption of a substance is followed by an unpleasant physical experience, normally nausea, but that no following repulsive or discomforting experience is necessary for the establishment of taste avoidance. Moreover, treatments that alleviate or prevent nausea do not impact the development or expression of taste avoidance, but they interfere with both the establishment and expression of taste aversion.
Which of the following statements can be concluded on the basis of the information given in the above passage?
  • a)
    The consumption of the food item is the cause of the following nausea that leads to the development of taste aversion.
  • b)
    The definitions of taste avoidance and taste aversion need to be revised to facilitate a clearer understanding of the concepts.
  • c)
    The development of taste aversion is faster for new food items that generate an unpleasant reaction on their first-time consumption than for nausea- causing foods that have been previously consumed without any unpleasant physical response.
  • d)
    The establishment or expression of taste aversion cannot be accompanied by the development of expression of taste avoidance. 
  • e)
    If a nausea-preventing medicine is administered in the time between the consumption of food and the following nausea, chances are that the development of taste aversion will be hindered.
Correct answer is option 'E'. Can you explain this answer?

Argument Analysis
 
Pre-Thinking
Conclusion Clarification
The author states that that (Even though the terms taste aversion and taste avoidance are sometimes used interchangeably,) there exists enough evidence to conclude that these two phenomena are likely not related to each other always.
Pre-Thinking Approach
In order to see what can be concluded on the basis of the information given in the passage, we need to observe all the given facts and see if the information in the passage is true, what must also be true.
Fact#1 – Research shows that taste aversion occurs when the consumption of a substance is followed by an unpleasant physical experience, normally nausea, but that no following repulsive or discomforting experience is necessary for the establishment of taste avoidance.
Conclusion 1: Since the above fact talks about the circumstance the two conditions develop, we can conclude that:
  • The circumstances leading up to taste avoidance and taste aversion are not always the same.  
Fact#2 –   Moreover, treatments that alleviate or prevent nausea do not impact the development or expression of taste avoidance, but they interfere with both the establishment and expression of taste aversion.
Conclusion 2:  The second facts talks about the impact of a kind of treatments on the two conditions. Such treatments fail to have any impact on either the development or expression of taste avoidance but do certainly impact both areas of taster aversion. Accordingly, we can conclude that:
  • Medications for the alleviation of nausea do not have the same impact on taste avoidance as they do on taste aversion.
With this pre-thinking in mind, let’s evaluate the answer choices.
Answer Choices
A
The consumption of the food item is the cause of the following nausea that leads to the development of taste aversion.
Incorrect - No information given
The passage states when the consumption of a food is followed by nausea, taste aversion is developed. This information does not give us any basis to conclude that it is the food that leads to the nausea in such cases; for instance, it is possible that the nausea is due to a viral infection and it is a mere coincidence that the consumption of the food happened before it. 
B
The definitions of taste avoidance and taste aversion need to be revised to facilitate a clearer understanding of the concepts.
Incorrect - No information given
The passage states that these terms are used interchangeably sometimes. This statement does not indicate whether the usage is because of the confusion in the definitions or that the definitions are absolutely perfect but the understanding, and hence the usage, isn’t.
C
The development of taste aversion is faster for new food items that generate an unpleasant reaction on their first-time consumption than for nausea- causing foods that have been previously consumed without any unpleasant physical response.
Incorrect - No information given
Firstly, we do not have any basis to conclude that it is the food item that causes an unpleasant reaction. Secondly, there is no information given to make an estimate about the rate of development of taste aversion in different situations.
D
The establishment or expression of taste aversion cannot be accompanied by the development of expression of taste avoidance. 
Incorrect - No information given
The passage states that these two phenomena are probably not always related and that the conditions present at the time of their development are not necessarily the same but that does not mean that they cannot developed or expressed at the same time.
E
If a nausea-preventing medicine is administered in the time between the consumption of food and the following nausea, chances are that the development of taste aversion will be hindered.
Correct
This choice can be derived on the basis of fact number 2 stated in the pre-thinking analysis. The fact that such medication “interferes” with the establishment of taste aversion gives us a basis to conclude this statement.

Dr. Atkins revolutionized the dieting world when he introduced the Atkins diet, a low-carb, high-protein, high-fat diet, which promises lifelong weight loss and maintenance.   However the American Heart Association (AHA) does not recommend this extremely low-carb diet.  It argues that Atkins Diet restricts intake of healthy carbs that provide essential nutrients to the body. Epidemiological studies have indicated that people who eat high-carbs diets have normal incidences of certain chronic diseases such as cardiovascular disease, certain cancers, type 2 diabetes, obesity, hypertension, and certain bone diseases, but such incidence of diseases is lower in people eating high-carbs diets than in people eating high-protein diets.
If the statements above are true, which of the following inference can be drawn by them?
  • a)
    Dr. Atkins revolutionized the dieting world when he introduced the Atkins diet, a low-carb, high-protein, high-fat diet, which promises lifelong weight loss and maintenance.   However the American Heart Association (AH
  • b)
    The diet revolution happened because Dr. Atkins pioneered the concept of high-protein, high-fat diet.
  • c)
    People who eat high-protein diets suffer from chronic diseases.
  • d)
    The more carbs you eat, the more healthy you will be.
  • e)
    The Atkins diet revolution may be beneficial for weight loss but may cause a higher than normal incidence of certain cardio vascular diseases.
Correct answer is option 'E'. Can you explain this answer?

If the statements above are true, which of the following inference can be drawn by them?
 
Pre-Thinking
  1. People who follow Atkins diet may experience weight loss as promised but may be at a higher risk for chronic diseases.
  2. People who eat healthy carbs experience lower incidence of chronic diseases.
Answer Choices
A
Atkins Diet is high in saturated fats, and as such it adversely affects blood lipid profiles (cholesterol, LDLs, HDLs).
The passage only talks about diet with regards to carb content and protein content.  Thus, this choice about fat content cannot be inferred from the passage.
B
The diet revolution happened because Dr. Atkins pioneered the concept of high-protein, high-fat diet.
The passage states that the Atkins diet revolutionized the dieting world. It does not mean that that the diet revolution happened because of the Atkins diet. For example, Apple revolutionized the cell phone industry does not imply that the cell phone revolution happened because of Apple. 
C
People who eat high-protein diets suffer from chronic diseases.
This passage states that people who eat high protein diet have higher incidence of suffering from chronic diseases.  This does not mean that everyone who eats high protein diet suffers from chronic disease.
D
The more carbs you eat, the more healthy you will be.
This cannot be inferred from the passage since the passage talks about the benefits of eating healthy carbs and not any carbs.
E
The Atkins diet revolution may be beneficial for weight loss but may cause a higher than normal incidence of certain cardio vascular diseases.
This choice echoes the inference # 1 as shown in the logical structure.

In a cooking competition, various family-owned restaurants cooked dishes made from recipes that have been in their families for generations.  The cake that won the competition was made from a recipe that head-chef Pierre Limore claims has been in his family for three generations since the 1940s. Although the sous-chef who actually baked the winning dish used an ingredient that has only recently become popular in the baking industry, around the late 1920s the same ingredient had been commonly used by chefs before it was temporarily declared unfit for human consumption. Which of the following can be concluded on the basis of the information given above?
  • a)
    The sous-chef who baked the cake was aware of the fact that the use of the specific ingredient would not violate the rules of the competition.
  • b)
    Had the head-chef Pierre Limore notified the authorities holding the competition of the list of ingredients, it is highly unlikely that his dish would have won the competition.
  • c)
    The use of the recipe used to bake the winning dish does not belie the claim made by the head-chef.
  • d)
    The authorities holding the competition had a mechanism to verify whether the recipes used in baking the dishes in the competition matched the original recipes first used to make the dishes.
  • e)
    To ensure that such competitions are fairly conducted, only chefs who can exactly replicate the original dish should be allowed to participate.

Argument Analysis
 
Pre-Thinking
Conclusion Clarification
The passage doesn’t state a conclusion. The question stem requires us to draw a conclusion based on the given information. Please note that the conclusion must be based only on the information provided in the passage.
Pre-Thinking Approach
In order to see what can be concluded from the argument, we  need to observe all the facts given in the argument and see if the information in the passage is true, what else must also be true.
Fact#1 –The head-chef claims that the recipe of the winning cake has been in his family for three generations since the 1940s.
Fact#2 – Although the sous-chef who actually baked the winning dish used an ingredient that has only recently become popular in the baking industry, around the late 1920s the same ingredient had been commonly used by chefs before it was temporarily declared unfit for human consumption.
Conclusion:
Since the ingredient was only temporarily declared unfit in the 1920s, it is possible that the ingredient used in the recipe could have been a part of the recipe that was initiated in to the head-chef’s family in the 1940s. Accordingly, one could deduce that:
The fact that the ingredient was temporary declared unfit for HC in the 1920s does not go against the claim made by the head chef.
 With this pre-thinking in mind, let’s evaluate the answer choices.

The residents of the city of Tibica are supplied water by two local corporations: TMC (Tibica Municipal Corporation) and TWMC (TibicaWater Management Corporation). Under pressure from the government, TMC recently increased its supply of water to the city. Even though TWMC maintained its supply level, the residents complained that their overall supply of water has reduced. Therefore, it seems likely that
Which of the following statements best completes the above passage?
  • a)
    In the recent past, the number of regions where the demand for water has increased has been greater than the number of regions where the demand for water has decreased.
  • b)
    In some areas of Tibica, the amount of water lost during distribution as a proportion of the amount of water supplied has increased.
  • c)
    The complaints made by the residents of Tibica against the corporations that supply water are always driven more by perception than by ground realities.
  • d)
    TMWC, which used to supply water uniformly across the city, has rearranged its distribution such that TMWC’s water supply in an area is proportional only to the demand in that area.
  • e)
    Even though TMC increased its supply of water to the city, it didn’t ensure that the supply was proportional to the demand.

- The passage mentions that even though TWMC maintained its supply level, the residents complained about a reduction in overall water supply.
- This suggests that there might be an issue with the distribution of water by TWMC.
- One possible reason could be an increase in the amount of water lost during distribution, leading to a perceived decrease in water supply for the residents.

Impact of water loss on overall supply:
- If TWMC is losing a significant amount of water during distribution, it can impact the overall supply reaching the residents.
- Despite maintaining the same supply level, the increased loss of water could result in less water actually reaching the residents, leading to their complaints about reduced water supply.

Importance of efficient water distribution:
- Efficient water distribution is crucial to ensure that the water supplied by corporations reaches the residents in the required quantity.
- Any significant increase in water loss during distribution can have a direct impact on the perceived water supply for the residents.

Therefore, option B, which suggests that in some areas of Tibica, the amount of water lost during distribution as a proportion of the amount of water supplied has increased, best completes the passage and provides a plausible explanation for the residents' complaints about reduced water supply despite an increase in supply by TMC.

A company cannot survive for long without at least one competitive advantage over the rest of the companies in the industry. With the latest technological developments, a company’s competitors can imitate its competitive advantage more easily than before. Besides, in this hyper-competitive world, building more than one competitive advantage is also not always possible.
Which of the following statements is best supported by the passage above?
  • a)
    For a company to survive in the long run, it needs to imitate the competitive advantage of all of its competitors, in addition to maintaining at least one competitive advantage.
  • b)
    No two companies producing the same products or services can survive in a marketplace in the long run.
  • c)
    A company needs to regularly replace existing competitive advantages with new competitive advantages in order to survive in the long run.
  • d)
    If two companies in an industry try to imitate each other’s competitive advantages, then both the companies will not be able to survive in the long run.
  • e)
    In the future, it is highly unlikely that imitating the competitive advantage of competitors will become difficult.
Correct answer is option 'C'. Can you explain this answer?

Pre-Thinking Approach
In order to see which statement can be best supported by the passage, we would need to observe all the facts given in the argument and see if the information in the passage is true, what must also be true.
Inferences: – From the information given in the passage, we can infer the following:
  • Ref. fact 1 and 2 in the logical structure
    • Inference – The competitors’ imitation of the competitive advantage(s) of a company is a threat to the long-term survival of the company.
  • Ref fact 1, 2 and 3 in the logical structure
    • Inference – If a company wants to survive in the long run, then it needs to focus on replacing the lost competitive advantages with new ones.
With this understanding in mind, let’s take a look at the option statements.
 
Answer Choices
A
For a company to survive in the long run, it needs to imitate the competitive advantage of all of its competitors, in addition to maintaining at least one competitive advantage.
Incorrect - No information given
This statement says that for survival, apart from having one or more competitive advantages, a company must imitate competitive advantages of all its competitors. However, the passage does not give us any information for this extra condition.
B
No two companies producing the same products or services can survive in a marketplace in the long run.
Incorrect - No information given
This option ignores the fact that it is possible for 2 companies to produce the same products / services and still survive as long as each company continuously maintains at least one competitive advantage over the other.
C
A company needs to regularly replace existing competitive advantages with new competitive advantages in order to survive in the long run.
Correct
This option is written along the lines of our pre-thinking combination of linkage 1 & 2. It is a combination of the three pieces of information given to us in the passage.
D
If two companies in an industry try to imitate each other’s competitive advantages, then both the companies will not be able to survive in the long run.
Incorrect - No information given
Even if the 2 companies imitate each other’s competitive advantages, as long as they are able to replace their own lost advantages with new competitive advantages, they can survive in the long run.
E
In the future, it is highly unlikely that imitating the competitive advantage of competitors will become difficult.
Incorrect - No information given
The passage just says that it has become easier for companies to imitate competitive advantages. The passage does not attempt to predict anything about the feasibility of imitating the advantages in the future.

Clearly, while comparing two companies, higher sales do not necessarily indicate higher profits. A recently published article in a prominent business magazine shows that the top ten names on the list of companies with the highest sales and the corresponding names on the list of companies with the highest profits are mutually exclusive.
Which of the following can properly be inferred based on the above statements?
  • a)
    While comparing two companies, the company with higher sales is more likely to have lower profits.
  • b)
    It is highly likely that two companies with different sales have the same profit margins.
  • c)
    Sales and profits have no correlation.
  • d)
    While comparing two companies, lower sales do not by themselves indicate lower profits.
  • e)
    In order to compete in the market, it is better for a company to have higher profits than higher sales.
Correct answer is option 'D'. Can you explain this answer?

Pre-Thinking
Conclusion Clarification
N/ A
Pre-Thinking Approach
In order to see which statement can be inferred by the passage, we need to observe all the facts given in the argument and see what must also be true if the information in the passage is true.
Linkage # 1
Since the given information shows that just by looking at the sales figures we cannot estimate the comparative profitability of two companies, we can infer that:
Inference1: The relative profitability of a company vis-a-vis another’s cannot be judged solely by looking at the companies’ sales figures.
Inference2:It is possible that even though a company has relatively lower sales, it is more profitable than the other company.
With this understanding in mind, let's take a look at the passage analysis.
Answer Choices
A
While comparing two companies, the company with higher sales is more likely to have lower profits.
Incorrect - No information given
The passage does not state any inverse correlation with sales and profits. It just says that higher sales do not always translate into higher profits.
B
It is highly likely that two companies with different sales have the same profit margins.
Incorrect - No information given
The passage makes no statement about similarity in profit margins.
C
Sales and profits have no correlation.
Incorrect - No information given
The passage states that higher sales do not always mean higher profits. This statement does not mean that for a company higher sales will not translate in to higher profits.
D
While comparing two companies, lower sales do not by themselves indicate lower profits.
Correct
This option is written along the lines of our pre-thinking per Inference # 2.
E
In order to compete in the market, it is better for a company to have higher profits than higher sales.
Incorrect - No information given
First of all, the author doesn’t say that a company cannot have both higher sales and profits. Second of all, the author never comments on what is better for competing in the market.

Cognitive dissonance, a concept proposed by behavioral analyst Leon Festinger, refers to a psychological condition in which individuals experience anxiety or even neurosis because they hold contradictory beliefs. The reverse situation, known as consonance, results when dissonance reaches a peak that forces the individual to move toward consonance. Therefore, no individual can arrive at cognitive consonance unless he or she first experiences the highest possible level of cognitive dissonance.
If the above statements are true, which of the following must also be true?
  • a)
    The higher the level of cognitive dissonance, the higher is the level of cognitive consonance achieved by the individual.
  • b)
    An individual experiencing cognitive consonance does not hold contradictory beliefs.
  • c)
    Cognitive consonance cannot be achieved unless cognitive dissonance is experienced first.
  • d)
    Cognitive dissonance cannot be treated using prescription medication.
  • e)
    Awareness of cognitive dissonance in itself is not sufficient to lead to cognitive consonance.
Correct answer is option 'C'. Can you explain this answer?

Conclusion Clarification
The question stem says that “If the above statements are true, which of the following must also be true?”. The question requires us to draw an inference based on statements in the passage. Please note that the inference must be based only on the information provided in the passage.
Pre-Thinking Approach
In order to see what can be inferred from the argument, we would need to observe all the facts given in the argument and see if the information in the passage is true, what must also be true.
Let us combine a couple of pieces of information presented in the passage:
  1. The reverse situation, known as consonance, results when dissonance reaches a peak that forces the individual to move toward consonance.
  2. No individual can arrive at cognitive consonance unless he or she first experiences the highest possible level of cognitive dissonance
Inference: Every individual who experiences consonance must have experienced highest levels of cognitive dissonance first.
With this understanding in mind, let's take a look at the answer choices.
Answer Choices
A
The higher the level of cognitive dissonance, the higher is the level of cognitive consonance achieved by the individual.
Incorrect - No information given
We only know that to arrive at consonance, one must experience the highest levels of dissonance. The argument does not talk about the levels of consonance that can be achieved.
B
An individual experiencing cognitive consonance does not hold contradictory beliefs.
Incorrect - No information given
The passage says that cognitive consonance is the opposite of dissonance. This means that people would not experience anxiety or neurosis. Therefore, it cannot be inferred whether people experiencing consonance will hold contradictory beliefs.
C
Cognitive consonance cannot be achieved unless cognitive dissonance is experienced first.
Correct
This matches the pre-thinking analysis and is the correct answer.
D
Cognitive dissonance cannot be treated using prescription medication.
Incorrect - No information given
How CD is treated is not mentioned in the argument.
E
Awareness of cognitive dissonance in itself is not sufficient to lead to cognitive consonance.
Incorrect - No information given
There is no information given regarding the impact of awareness of CD on achieving CC. Therefore, this statement cannot be derived from the passage.

The INES scale was created in 1990 as a way of indicating the relative seriousness of incidents in which radioactivity is released at nuclear plants. Before that, various countries relied upon their own classification systems, making it difficult to compare a nuclear mishap that occurred in the U.S. with one in, say, Europe or Japan.
Which of the following statements is best supported by the above passage?
  • a)
    After 1990, the implementation of the INES scale is expected to have led to a reduction in the amount of damage caused by nuclear mishaps.
  • b)
    A common scale of measurement is likely to better facilitate a comparison of the relative seriousness of incidents across nations, incidents in which radio-activity is released at nuclear plants. 
  • c)
    The ability to compare the relative seriousness of incidents in which radioactivity is released at nuclear plants in different parts of the US is expected to have increased after the creation of INES in 1990.
  • d)
    It is very likely that most countries currently use the INES scale to communicate the relative seriousness of incidents in which radioactivity is released at nuclear plants.
  • e)
    In the absence of the INES scale, it would have been currently very difficult to compare nuclear mishaps in the US with those in Europe or Japan.

Pre-Thinking
Conclusion Clarification
N/A
Pre-Thinking Approach
The question stem requires us to look for a statement that is best supported by the information given in the passage. So let’s look at the same and see what we can derive from it.
We know from Before 1990 and NM in different countries (refer to the logical structure diagram above) that comparison was difficult when countries used their own CS.
Since, INES was created in 1990 to measure RS of incidents across countries, which were using different CS, we can infer that:
  • It’s likely that a common scale can overcome the difficulty faced in measuring the RS of NM across countries where different CS are used.
With this understanding in mind, let’s take a look at the option statements.
Answer Choices
A
After 1990, the implementation of the INES scale is expected to have led to a reduction in the amount of damage caused by nuclear mishaps.
Incorrect - No information given
INES just measures  RS of NM, it has no impact on the damage caused.
B
A common scale of measurement is likely to better facilitate a comparison of the relative seriousness of incidents across nations, incidents in which radio-activity is released at nuclear plants. 
Correct
This choice is written along the lines of our pre-thinking.
C
The ability to compare the relative seriousness of incidents in which radioactivity is released at nuclear plants in different parts of the US is expected to have increased after the creation of INES in 1990.
Incorrect - No information given
First of all, we don’t know whether the US adopted the INES scale. Secondly, and more importantly, the passage says the difficulty was faced in measuring RS across countries, not within the same country.
D
It is very likely that most countries currently use the INES scale to communicate the relative seriousness of incidents in which radioactivity is released at nuclear plants.
Incorrect - No information given
We have no evidence that INES was actually adopted in different countries.
E
In the absence of the INES scale, it would have been currently very difficult to compare nuclear mishaps in the US with those in Europe or Japan.
Incorrect - No information given
From the passage, we don’t know if INES was actually adopted in these countries. Similarly, we can’t say that another scale wouldn't have been created in the absence of INES. So, we cannot conclude anything about the hypothetical situation mentioned in this choice. 

Two different concepts, copyright infringement and plagiarism, are often confused for each other. Copyright infringement deals with the unauthorized use of copyright material and hence the violation of the rights of the copyright holder. Plagiarism, on the other hand, is concerned with false claims of authorship of ideas, works etc. that may not necessarily be protected under copyright. Moreover, even if a person gets the permission to use copyright material, it may still account for plagiarism if the person tries to falsely claim the authorship of the material.
 Which of the following must be true on the basis of the information given in the above argument?
  • a)
    Plagiarism may not always amount to copyright infringement but copyright infringement always amounts to plagiarism.
  • b)
    Any unauthorized use of material that has been protected under copyright will be considered plagiarism. 
  • c)
    Under certain conditions, use of copyright free material can still be considered plagiarism.
  • d)
    Even authorized use of copyright material amounts to plagiarism.
  • e)
    In a court of law, it is easier to prove a case of copyright infringement than a case of plagiarism.
Correct answer is 'C'. Can you explain this answer?

Ishani Rane answered
Contrary to popular belief, the word plagiarism is not synonymous with copyright infringement. Not every incident of plagiarism is copyright infringement, especially when public domain works are involved. On the flip side, not every incident of copyright infringement is plagiarism, such as the alleged infringements of file sharers.

On a related note, not all reuse of copyrighted material is copyright infringement or plagiarism. Some uses are perfectly legal and ethical, thus getting them dubbed “fair use”.

The important thing to remember, though, is that plagiarism refers to using someone else’s work without providing attribution. Though it’s possible to infringe upon a copyright while attributing a source properly, it is not possible to plagiarize.

Organizations with growing data needs can create more space by either compressing their existing data (called Deduping) or adding additional storage tape disks. In most instances, the cost of deduping is 10% lower than the cost of installing additional tape drives for taking backups.  It is true that one must take more frequent backups with deduping.  This incurs some extra bandwidth charges. Even after bandwidth charges, it is still cheaper for an organization to Dedupe than to add tape drives to increase storage.The statements above, if true, best support which of the following assertions?
  • a)
    Installation time of dedupe disk system is 10% less than the installation time of tape drives.
  • b)
    Switching from tape drives to dedupe disk system will eliminate 10% of tape-drives that are currently used in computers today.
  • c)
    The bandwidth charges required for replication after deduping is less than 10% of the cost of installing tape drives.
  • d)
    The cost of replicating backups after deduping is more than 10% of the cost of installing dedupes.
  • e)
    It takes 10% less time to compress the files using Dedupe than it does to backup files using tape drives.

The statements above, if true, best support which of the following assertions?
 
Pre-Thinking
  1. Bandwidth charges for taking back-ups is less than 10% of the cost of installation of tape drives
Answer Choices
A
Installation time of dedupe disk system is 10% less than the installation time of tape drives.
The passage only talks about installation costs and not about installation time.
B
Switching from tape drives to dedupe disk system will eliminate 10% of tape-drives that are currently used in computers today.
This choice is an ISWAT.  It uses the term 10% as used in the passage but changes the context of the term.
C
The bandwidth charges required for replication after deduping is less than 10% of the cost of installing tape drives.
Based on following two data points of the costs, this choice can be inferred.
  1. Installation Cost of DeDupe = Installation Cost of Tape Drives – 10% (installation cost of tape drives)
  2. Cost of DeDupe + Bandwidth Charges < Cost of Tape DrivesClearly the bandwidth charges are less than 10% of the installation cost of tape drives.
D
The cost of replicating backups after deduping is more than 10% of the cost of installing dedupes.
This is opposite to what can be inferred from the passage.
E
It takes 10% less time to compress the files using Dedupe than it does to backup files using tape drives.
The passage only compares the cost of using the two systems.  It does not compare the time that it takes to compress the files.

Argument Analysis
 
Pre-Thinking
Conclusion Clarification
N/A
Pre-Thinking Approach
The question asks us to find a statement which must be true if the information given in the passage is true.
Let’s take a small example with numbers in order to draw inferences.
Suppose the number of students in Junior and Senior classes is 50 and 100 respectively. Let’s further divide this number so that the condition given in the passage is true:
 
 
As you can see the 3rd column satisfies the condition that % of students with grades > 80% is higher in JC whereas the last column satisfies the condition that % of students with grades > 90% is higher in SC. Now let’s divide the proportion of students scoring above 80% in two categories:
  1. Those between 80 and 90%
  2. Those above 90%
 Doing so would help us visualize the information clearly.
Table A
Now if the proportion of students in JC scoring above 80% is higher than that in SC but the proportion is lower in case of students scoring above 90%, then there must be students in JC who are scoring between 80 and 90%. The table above illustrates this. If this weren’t so, i.e. if there were no students in JC scoring between 80 and 90%, then the table would look like this:
 
Now the last column doesn’t satisfy the information given in the passage that proportion of students scoring >90% grades is higher in SC.  Therefore, our earlier understanding is correct that there must be some students in JC who have grades between 80 and 90%.
Please note that the example quoted here is only to explain the passage more clearly and we should focus only on the proportions mentioned in the table and not on the absolute numbers as they can be quite different from the ones given in the table and any inference regarding a comparison of absolute numbers might not hold. The table given below illustrates this point by reversing the number of students in JC and SC.
With this understanding in mind, let's take a look at the option statements.
Answer Choices
A
The average class grade of the senior class is higher than that of the junior class.
Incorrect - No information given
The information regarding average class grade cannot be inferred as the passage only talks about students scoring above 80%.
B
The number of students with grades above 80 percent is greater in the junior class than in the senior class.
Incorrect - No information given
We can’t infer any comparative information regarding absolute numbers as the passage only talks about proportions.
C
The number of students with grades lower than 80 percent is greater in the senior class than in the junior class.
Incorrect - No information given
We can’t infer any comparative information regarding absolute numbers as the passage only talks about proportions.
D
Some students in the junior class have grades between 80 percent and 90 percent.
Correct
This is same as the understanding we reached during the pre-thinking phase.
E
The number of students with grades above 90 percent is higher in the senior class than in the junior class.
Incorrect - No information given
We can’t infer any comparative information regarding absolute numbers as the passage only talks about proportions.

During their first few months, newborns grow 0.25 inch or more per week.  Vitamin D is a key ingredient that helps them grow faster. Only Enfamil baby food has Krimprotein, which enables newborns grow faster and achieve their full growth potential.

  • a)
    Newborns need external sources of Vitamin D to reach their full grown potential.
  • b)
    Only Enfamil can provide Vitamin D that newborns need to reach their full growth potential.
  • c)

Argument Analysis
During their first few months, newborns grow 0.25 inch or more per week.  Vitamin D is a key ingredient that helps them grow faster. Only Enfamil baby food has Krimprotein, which enables newborns grow faster and achieve their full growth potential.
 
Pre-Thinking
  1. If newborn takes Enfamil baby food in first few months, then he will most likely grow > 0.25 inch/week.
  2. If newborn takes Vitamin D  in first few months, then he will most likely grow > 0.25 inch/week.
Answer Choices
A
Newborns need external sources of Vitamin D to reach their full grown potential.
The passage states that Vitamin D is required for New borns to reach their full growth potential. It by no means implies that that Vitamin D must be acquired through external sources.
B
Only Enfamil can provide Vitamin D that newborns need to reach their full growth potential.
The passage states that “only Enfamil contains Krimprotein “. This does not mean that only Enfamil contains Vitamin D as there could be a lot of sources of Vitamin D. 
C
None of Enfamil competitors have Krimprotein in their baby food offerings.
This statement is the re-statement of the premise in the passage.  The passage states that Only Enfamil has Krimprotein.  This implies that no one else has Krimprotein.   Hence this is the correct inference.
D
Newborns who do not take enough Vitamin D fail to grow 0.25 inch per week.
The passage states that Vitamin D is required for New borns to reach their full growth potential. It by no means implies that that Vitamin D must be acquired through external sources.
E
Newborns cannot get Vitamin D from any other source other than Krimprotein.
This statement uses the terms used in the passage but presents it in twisted and incorrect manner.
 

The playwright Bertolt Brecht staged his plays using a technique known as Verfremdungseffekt or the ‘alienation effect’ to prevent his audience from becoming too involved with the action taking place on the stage, thereby enabling viewers to reflect intellectually on the themes presented to them. While this technique was probably usable in a pre-World War II era, as then it was still possible to expect art to present objective perspectives on reality, it is clearly invalid in the twenty-first century.
Which of the following can most properly be concluded from the statements above?

In order to see what can be concluded from the argument, we need to observe all the information given in the argument since the correct inference or conclusion would be based purely on this information.
Statement#1 – The playwright Bertolt Brecht staged his plays using the ‘alienation effect’ to prevent his audience from becoming too involved with the action taking place on the stage, thereby enabling viewers to reflect intellectually on the themes presented to them.
From the stated intention behind the use of alienation effect during Brecht’s time, we can conclude that:
  • Conclusion 1: Becoming overly involved with the action taking place on the stage would interfere with the audience’s intellectual reflection on the themes presented to them.
Statement#2 – While this technique was probably usable in a pre-World War II era, as then it was still possible to expect art to present objective perspectives on reality, it is clearly invalid in the twenty-first century.
From the reason cited for the usability of the technique in the pre WWII era, we can conclude that
  • Conclusion 2: Presenting objective perspectives on reality is key for using the technique of alienation effect.
With this pre-thinking in mind, let’s evaluate the answer choices.

The gun lobby’s attempt to stop doctors from warning about the severe risks posed by guns in  homes is outrageous and unconstitutional. Children aged 5 to 14 years in the United States are 11 times more likely to be killed accidentally with a gun than similarly aged children in other developed countries are. Moreover, more than 40 percent of gun-owning households with children store their guns unlocked, and one quarter of these homes store them loaded. 
  • a)
    children must be provided proper counseling in schools on the dangers associated with the use of guns.
  • b)
    the United States must learn from other developed countries on reducing the murder rate.
  • c)
    doctors must be allowed to give patients frank advice about the risks posed by guns in the home.

    children aged 5 to 14 years must be provided special protection to protect them from gun related crimes.
Correct answer is option 'C'. Can you explain this answer?

Kiran Chauhan answered
The gun lobby’s attempt to stop doctors from warning about the severe risks posed by guns in  homes is outrageous and unconstitutional. Children aged 5 to 14 years in the United States are 11 times more likely to be killed accidentally with a gun than similarly aged children in other developed countries are. Moreover, more than 40 percent of gun-owning households with children store their guns unlocked, and one quarter of these homes store them loaded. 
The considerations given best serve as part of the argument that
Argument Analysis
 
Pre-Thinking
Conclusion Clarification
Although the author does provide us with an opinion, the question stem asks us to look for a concluding statement in the answer choices.
Pre-Thinking Approach
In order to see which statement can be best supported by the passage, we would need to observe all the facts given in the argument and see if the information in the passage is true, what must also be true.
Inferences:
The conclusion of the argument will be a culmination of the opinion expressed by the author and the facts cited to support the same. We can see that the author thinks that:
  • GB’s mentioned attempts are outrageous and unconstitutional.
All the reasons cited by the author to support the above opinion are related with the risks guns kept at home pose to the children in such homes and in general. Therefore, one can conclude that the author is arguing that:
  • The doctors should have the right to educate patients about the risks guns kept at home pose to people, especially children.
With this understanding in mind, let's take a look at the option statements.
Answer Choices
A
children must be provided proper counseling in schools on the dangers associated with the use of guns.
Incorrect - No information given
The passage doesn’t talk about the overall dangers of guns, only about the risks of guns at homes. The role of schools or counselling is never brought up. The information given in the passage is about the doctors warning about the risks posed by the guns.
B
the United States must learn from other developed countries on reducing the murder rate.
Incorrect - No information given
The passage clearly states ‘killed accidentally,’ not ‘murdered.’ So this can’t be concluded from the passage.
c
doctors must be allowed to give patients frank advice about the risks posed by guns in the home.
Correct
This option is written along the lines of our pre-thinking. It is a combination of all the information given to us in the passage and hence can be safely concluded.
D
the gun lobby should be allowed to express its views.
Incorrect - No information given
This can’t be concluded from the passage. On the contrary, the author terms their attempts to stop doctors from advising their patients as outrageous and unconstitutional.
E
children aged 5 to 14 years must be provided special protection to protect them from gun related crimes.
Incorrect - No information given
The option is veering away from the topic of accidental deaths and bringing up gun related crimes. This can’t be inferred from the passage.

The length of a bee’s tongue is proportional to the size of the bee, but it is also true that this proportion is inherited by each bee. Furthermore, the bee tongue is usually sized to match the depth of the flower it pollinates, making it possible for the bee to drink the nectar from it. Accordingly, there are both short-tongued and long-tongued bees that drink nectar only from flowers suited to their tongue size. Such bees are called specialists and since they depend on just a few flowers, they are quite vulnerable to changes in nature.
  • a)
    It is by studying the species of flower a bee pollinates that entomologists determine the exact body size of the bee and the species it belongs to.
  • b)
    It is likely that a short tongued bee may have a problem drinking nectar from a flower that has a longer than average depth but a long tongued bee can easily sap the nectar of any kind of flower.
  • c)
    Drastic changes in the flora of a land could affect the existence of certain bee species.
  • d)
    The type of honey produced by the bees depends heavily on the flowers they pollinate.
  • e)
    Across various bee species, the kind of flower a particular type of bee pollinates is exclusive from that pollinated by another type of bee.
Correct answer is option 'C'. Can you explain this answer?

If the information given above is true, then which of the following can be concluded from it?
Argument Analysis

Conclusion Clarification
N/ A
Pre-Thinking Approach
In order to see which statement can be best supported by the passage, we would need to observe all the facts given in the argument and see what must also be true if the information in the passage is true. Please note that the inference/conclusion must be based only on the given information.
Inferences:
  • From fact 2 (ref.: logical structure)
    • Inference1: The size of the bee’s tongue and the depth of the flower it pollinates are mostly linked to each other.
  • Combining facts 3 & 4(ref.: logical structure)
    • Inference 2: Genetic changes such as those made to the size, colour, and shape of certain flower species could affect the species of bee dependent on it.
With this understanding in mind, let’s take a look at the option statements.
 
Answer Choices
A
It is by studying the species of flower a bee pollinates that entomologists determine the exact body size of the bee and the species it belongs to.
Incorrect - No information given
The passage states only general facts about bees. It doesn’t give us any information on the methodology followed by entomologists.
B
It is likely that a short tongued bee may have a problem drinking nectar from a flower that has a longer than average depth but a long tongued bee can easily sap the nectar of any kind of flower.
Incorrect - No information given
C
The passage clearly states that both short-tongued and long-tongued bees drink nectar only from flowers suited to their tongue size. Thus we can’t conclude that long tongued bees can sap the nectar of any kind of flower.
Drastic changes in the flora of a land could affect the existence of certain bee species.
Correct
This option is written along the lines of our pre-thinking Inference 2. Since these bees are dependent on only certain flowers, significant changes in the plant species of an area could affect their survival.
D
The type of honey produced by the bees depends heavily on the flowers they pollinate.
Incorrect - No information given
The passage doesn’t give us any information to conclude on the type of honey produced by the bees.
E
Across various bee species, the kind of flower a particular type of bee pollinates is exclusive from that pollinated by another type of bee.
Incorrect - No information given
The passages make no distinction between the pollination of flowers by one bee species and that by another type of bee. Thus the given information can’t be concluded from the passage.
