CAT 2020 Slot 2: Past Year Question Paper - Question 1

Direction for Reading Comprehension: The pass ages given here are followed by question that have four answer choices; read the passage carefully and pick the option whose answer best aligns with the passage

Aggression is any behavior that is directed toward injuring, harming, or inflicting pain on another living being or group of beings. Generally, the victim(s) of aggression must wish to avoid such behavior in order for it to be considered true aggression. Aggression is also categorized according to its ultimate intent. Hostile aggression is an aggressive act that results from anger, and is intended to inflict pain or injury because of that anger. Instrumental aggression is an aggressive act that is regarded as a means to an end other than pain or injury. For example, an enemy combatant may be subjected to torture in order to extract useful intelligence, though those inflicting the torture may have no real feelings of anger or animosity toward their subject. The concept of aggression is very broad, and includes many categories of behavior (e.g., verbal aggression, street crime, child abuse, spouse abuse, group conflict, war, etc.). A number of theories and models of aggression have arisen to explain these diverse forms of behavior, and these theories/models tend to be categorized according to their specific focus. The most common system of categorization groups the various approaches to aggression into three separate areas, based upon the three key variables that are present whenever any aggressive act or set of acts is committed. The first variable is the aggressor him/herself. The second is the social situation or circumstance in which the aggressive act(s) occur. The third variable is the target or victim of aggression.

Regarding theories and research on the aggressor, the fundamental focus is on the factors that lead an individual (or group) to commit aggressive acts. At the most basic level, some argue that aggressive urges and actions are the result of inborn, biological factors. Sigmund Freud (1930) proposed that all individuals are born with a death instinct that predisposes us to a variety of aggressive behaviors, including suicide (self directed aggression) and mental illness (possibly due to an unhealthy or unnatural suppression of aggressive urges). Other influential perspectives supporting a biological basis for aggression conclude that humans evolved with an abnormally low neural inhibition of aggressive impulses (in comparison to other species), and that humans possess a powerful instinct for property accumulation and territorialism. It is proposed that this instinct accounts for hostile behaviors ranging from minor street crime to world wars. Hormonal factors also appear to play a significant role in fostering aggressive tendencies. For example, the hormone testosterone has been shown to increase aggressive behaviors when injected into animals. Men and women convicted of violent crimes also possess significantly higher levels of testosterone than men and women convicted of nonviolent crimes. Numerous studies comparing different age groups, racial/ethnic groups, and cultures also indicate that men, overall, are more likely to engage in a variety of aggressive behaviors (e.g., sexual assault, aggravated assault, etc.) than women. One explanation for higher levels of aggression in men is based on the assumption that, on average, men have higher levels of testosterone than women.

The author identifies three essential factors according to which theories of aggression are most commonly categorised. Which of the following options is closest to the factors identified by the author?

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 1

This is the easiest question of the passage. The clue to the right answer is given in the last part of the first paragraph. Reading that part is enough to spot the right choice. It says there are three variables present in an aggressive act. They are: the aggressor, the circumstances, and the victim.

The author discusses all of the following arguments in the passage EXCEPT that:

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 2

We must remember that this is an except question. We must pick the choice that is not presented as the author’s argument. Choice 1 goes out because the author discusses it towards the end of the passage. Men have higher levels of testosterone, resulting in higher aggression. The second sentence of the last paragraph provides clue for choice 2. Thus 2 is also eliminated. The first paragraph elaborately describes the varying nature of aggression. Thus 3 also is eliminated. The moderation of death instinct is nowhere discussed in the passage, although the presence of death instinct is discussed. Thus 4 is the right choice.

All of the following statements can be seen as logically implied by the arguments of the passage EXCEPT:

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 3

Though this is an except question, this question can be easily answered if we look for the phrase “neural regulation” in the passage. The neural inhibition has been discussed with regards to aggressive impulses, not the hormone testosterone. Thus 2 is definitely not implied by the author. Once we have found the right answer there is no need to verify the others. The rest of the options, however, do find indirect reference in the passage.

“[A]n enemy combatant may be subjected to torture in order to extract useful intelligence, though those inflicting the torture may have no real feelings of anger or animosity toward their subject.” Which one of the following best explicates the larger point being made by the author here?

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 4

The point made by the author in the quoted remark is that you may be aggressive without any real feelings of anger or animosity. Why? Because inflicting pain is not the objective, but serves some other end. Thus 3 directly becomes the right choice. 

CAT 2020 Slot 2: Past Year Question Paper - Question 5

Direction for Reading Comprehension: The pass ages given here are followed by question that have four answer choices; read the passage carefully and pick the option whose answer best aligns with the passage

174 incidents of piracy were reported to the International Maritime Bureau last year, with Somali pirates responsible for only three. The rest ranged from the discreet theft of coils of rope in the Yellow Sea to the notoriously ferocious Nigerian gunmen attacking and hijacking oil tankers in the Gulf of Guinea, as well as armed robbery off Singapore and the Venezuelan coast and kidnapping in the Sundarbans in the Bay of Bengal. For [Dr. Peter] Lehr, an expert on modern-day piracy, the phenomenon’s history should be a source of instruction rather than entertainment, piracy past offering lessons for piracy present. . . .

But . . . where does piracy begin or end? According to St Augustine, a corsair captain once told Alexander the Great that in the forceful acquisition of power and wealth at sea, the difference between an emperor and a pirate was simply one of scale. By this logic, European empire-builders were the most successful pirates of all time. A more eclectic history might have included the conquistadors, Vasco da Gama and the East India Company. But Lehr sticks to the disorganised small fry, making comparisons with the renegades of today possible.

The main motive for piracy has always been a combination of need and greed. Why toil always a starving peasant in the 16th century when a successful pirate made up to £4,000 on each raid? Anyone could turn to freebooting if the rewards were worth the risk . . . .

Increased globalisation has done more to encourage piracy than suppress it. European colonialism weakened delicate balances of power, leading to an influx of opportunists on the high seas. A rise in global shipping has meant rich pickings for freebooters. Lehr writes: “It quickly becomes clear that in those parts of the world that have not profited from globalisation and modernisation, and where abject poverty and the daily struggle for survival are still a reality, the root causes of piracy are still the same as they were a couple of hundred years ago.” . . .

Modern pirate prevention has failed. After the French yacht Le Gonant was ransomed for $2million in 2008, opportunists from all over Somalia flocked to the coast for a piece of the action. . . . A consistent rule, even today, is there are never enough warships to patrol pirate-infested waters. Such ships are costly and only solve the problem temporarily; Somali piracy is bound to return as soon as the warships are withdrawn. Robot shipping, eliminating hostages, has been proposed as a possible solution; but as Lehr points out, this will only make pirates switch their targets to smaller carriers unable to afford the technology.

His advice isn’t new. Proposals to end illegal fishing are often advanced but they are difficult to enforce. Investment in local welfare put a halt to Malaysian piracy in the 1970s, but was dependent on money somehow filtering through a corrupt bureaucracy to the poor on the periphery. Diplomatic initiatives against piracy are plagued by mutual distrust: The Russians execute pirates, while the EU and US are reluctant to capture them for fear they’ll claim asylum.

“Why toil away as a starving peasant in the 16th century when a successful pirate made up to £4,000 on each raid?” In this sentence, the author’s tone can best be described as being:

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 5

This is a passage easy to read and understand. The very first question is author’s tone in the given sentence. Indignant means angry, but there is no anger as the author is relating to something that used to happen 400 years ago. The author is not trying to be analytical, rather he is trying to be ironical. Irony is used to highlight a situation by using contrast in an amusing way. His intention is not to discuss the contrast between peasant life and pirate life way back in the 16th century. 3 is the best choice.

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 6

The author by giving the example of Vasco da Gama and the east India company to suggest that they both were not very different from piracy. Options 2 brings out that suggestion appropriately. 1 goes out because the author does consider them as pirates. 3 might look like a good choice but the phrase “laid the ground for modern piracy” brings something that is not implied or stated in the passage. 4 could have been another close choice, but the author’s intention is not to compare the disorganized piracy of today with the organized piracy of the past. His intention is to compare the disorganized small piracy of the past with the renegades of today. It is small Vs small, and not small Vs big. 2 is the right answer.

We can deduce that the author believes that piracy can best be controlled in the long run:

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 7

At the end of the fourth paragraph the author says that “root causes of piracy today are the same as they were a couple of hundred years ago”. What were the causes a couple of hundred years ago? According to the author it is poverty. Thus he believes that eliminating poverty will solve the problem. Thus 3 is the right choice. All the other choices are mentioned only to show that they haven’t brought the desired results.

The author ascribes the rise in piracy today to all of the following factors EXCEPT:

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 8

We have to pick the choice that is not the cause behind the rise in piracy. 1 goes out because it is the cause. The first sentence of the fourth paragraph offers the clue. The third paragraph says that “the main motive for piracy has always been a combination of need and greed...”. Thus 3 also is correct, as a cause of piracy. The fourth paragraph has clue to option 4 as well. Thus 2 is the right choice. The author believes that surveillance can never be an effect solution because it is not addressing the root cause.

CAT 2020 Slot 2: Past Year Question Paper - Question 9

Direction for Reading Comprehension: The pass ages given here are followed by question that have four answer choices; read the passage carefully and pick the option whose answer best aligns with the passage

The claims advanced here may be condensed into two assertions: [first, that visual] culture is what images, acts of seeing, and attendant intellectual, emotional, and perceptual sensibilities do to build, maintain, or transform the worlds in which people live. [And second, that the] study of visual culture is the analysis and interpretation of images and the ways of seeing (or gazes) that configure the agents, practices, conceptualities, and institutions that put images to work. . . .

Accordingly, the study of visual culture should be characterized by several concerns. First, scholars of visual culture need to examine any and all imagery – high and low, art and non art.. . . They must not restrict themselves to objects of a particular beauty or aesthetic value. Indeed, any kind of imagery may be found to offer up evidence of the visual construction of reality. . . .

Second, the study of visual culture must scrutinize visual practice as much as images themselves, asking what images do when they are put to use. If scholars engaged in this enterprise inquire what makes an image beautiful or why this image or that constitutes a masterpiece or a work of genius, they should do so with the purpose of investigating an artist’s or a work’s contribution to the experience of beauty, taste, value, or genius. No amount of social analysis can account fully for the existence of Michelangelo or Leonardo. They were unique creators of images that changed the way their contemporaries thought and felt and have continued to shape the history of art, artists, museums, feeling, and aesthetic value. But study of the critical, artistic, and popular reception of works by such artists as Michelangelo and Leonardo can shed important light on the meaning of these artists and their works for many different people. And the history of meaning-making has a great deal to do with how scholars as well as lay audiences today understand these artists and their achievements.

Third, scholars studying visual culture might properly focus their interpretative work on lifeworlds by examining images, practices, visual technologies, taste, and artistic style as constitutive of social relations. The task is to understand how artifacts contribute to the construction of a world. . . . Important methodological implications follow: ethnography and reception studies become productive forms of gathering information, since these move beyond the image as a closed and fixed meaning-event. . . .

Fourth, scholars may learn a great deal when they scrutinize the constituents of vision, that is, the structures of perception as a physiological process as well as the epistemological frameworks informing a system of visual representation. Vision is a socially and a biologically constructed operation, depending on the design of the human body and how it engages the interpretive devices developed by a culture in order to see intelligibly. . . . Seeing . . . operates on the foundation of covenants with images that establish the conditions for meaningful visual experience.

Finally, the scholar of visual culture seeks to regard images as evidence for explanation, not as epiphenomena.

“No amount of social analysis can account fully for the existence of Michelangelo or Leonardo.” In light of the passage, which one of the following interpretations of this sentence is the most accurate?

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 9

This is so simple a question that one will not feel like marking the right choice just because it is too straightforward. The author in the third paragraph says that the study of visual culture is very important to understand the agents, practices and institutions that put images to work. Then he further goes to say that “no amount of social analysis (visual culture) can account fully for the existence of Michelangelo or Leonardo. They were unique creators. Choice 4 is very close to this statement. It is so easy that one is highly likely to miss out on this. Choice 2 is close but a little absurd. It says that because they are genius they cannot be subjected to social analysis. The author says that we may have social analysis of these artists but no matter how much we analyse; the analysis may not be enough.

Direction for Reading Comprehension: The pass ages given here are followed by question that have four answer choices; read the passage carefully and pick the option whose answer best aligns with the passage

The claims advanced here may be condensed into two assertions: [first, that visual] culture is what images, acts of seeing, and attendant intellectual, emotional, and perceptual sensibilities do to build, maintain, or transform the worlds in which people live. [And second, that the] study of visual culture is the analysis and interpretation of images and the ways of seeing (or gazes) that configure the agents, practices, conceptualities, and institutions that put images to work. . . .

Accordingly, the study of visual culture should be characterized by several concerns. First, scholars of visual culture need to examine any and all imagery – high and low, art and non art.. . . They must not restrict themselves to objects of a particular beauty or aesthetic value. Indeed, any kind of imagery may be found to offer up evidence of the visual construction of reality. . . .

Second, the study of visual culture must scrutinize visual practice as much as images themselves, asking what images do when they are put to use. If scholars engaged in this enterprise inquire what makes an image beautiful or why this image or that constitutes a masterpiece or a work of genius, they should do so with the purpose of investigating an artist’s or a work’s contribution to the experience of beauty, taste, value, or genius. No amount of social analysis can account fully for the existence of Michelangelo or Leonardo. They were unique creators of images that changed the way their contemporaries thought and felt and have continued to shape the history of art, artists, museums, feeling, and aesthetic value. But study of the critical, artistic, and popular reception of works by such artists as Michelangelo and Leonardo can shed important light on the meaning of these artists and their works for many different people. And the history of meaning-making has a great deal to do with how scholars as well as lay audiences today understand these artists and their achievements.

Third, scholars studying visual culture might properly focus their interpretative work on lifeworlds by examining images, practices, visual technologies, taste, and artistic style as constitutive of social relations. The task is to understand how artifacts contribute to the construction of a world. . . . Important methodological implications follow: ethnography and reception studies become productive forms of gathering information, since these move beyond the image as a closed and fixed meaning-event. . . .

Fourth, scholars may learn a great deal when they scrutinize the constituents of vision, that is, the structures of perception as a physiological process as well as the epistemological frameworks informing a system of visual representation. Vision is a socially and a biologically constructed operation, depending on the design of the human body and how it engages the interpretive devices developed by a culture in order to see intelligibly. . . . Seeing . . . operates on the foundation of covenants with images that establish the conditions for meaningful visual experience.

Finally, the scholar of visual culture seeks to regard images as evidence for explanation, not as epiphenomena.

“Seeing . . . operates on the foundation of covenants with images that establish the conditions for meaningful visual experience.” In light of the passage, which one of the following statements best conveys the meaning of this sentence?

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 10

This question asks us to interpret a phrase given in the passage. For meaningful visual experience, we need the conditions, which operate on the foundation of covenants. 3 precisely captures that meaning. In fact, the question asks us to pick the option that is similar in content to the one given in the question. 1 could have been close but it distorts the idea by saying “when there is foundational condition established in images”. It suggests that the foundation is established in images. Only 3 correctly rephrases the whole idea given in the question

Which set of keywords below most closely captures the arguments of the passage?

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 11

This was an easy question. Two keywords are very important, one is visual images or imagery, and the other is visual culture or practices. Both these are important as per the first paragraph of the passage and only in choice 3 can we find these two keywords. Thus 3 is the best choice. 4 misses on imagery or visual images. 2 misses on the visual culture. 1 misses both visual culture and images.

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 12

We have to mark the choice that is not a valid inference. 2 can be inferred from last paragraph. 4 can be inferred from the first paragraph, and also the paragraph that discusses Michelangelo and Leonardo. In the third last paragraph the author says “how artifacts contribute to the construction of a world...”. Thus 3 also can be inferred. 1 cannot be inferred because structures of perception have been discussed as a physiological process, not as an institutional structure. Thus 1 is farfetched and the right choice as it cannot be inferred.

In a low-carbon world, renewable energy technologies are hot business. For investors looking to redirect funds, wind turbines and solar panels, among other technologies, seem a straightforward choice. But renewables need to be further scrutinized before being championed as forging a path toward a low-carbon future. Both the direct and indirect impacts of renewable energy must be examined to ensure that a climate-smart future does not intensify social and environmental harm. As renewable energy production requires land, water, and labor, among other inputs, it imposes costs on people and the environment. Hydropower projects, for instance, have led to community dispossession and exclusion . . .Renewable energy supply chains are also intertwined with mining, and their technologies contribute to growing levels of electronic waste . . . Furthermore, although renewable energy can be produced and distributed through small-scale, local systems, such an approach might not generate the high returns on investment needed to attract capital.

Although an emerging sector, renewables are enmeshed in long-standing resource extraction through their dependence on minerals and metals . . . Scholars document the negative consequences of mining . . . even for mining operations that commit to socially responsible practices[:] “many of the world’s largest reservoirs of minerals like cobalt, copper, lithium,[and] rare earth minerals”—the ones needed for renewable technologies— “are found in fragile states and under communities of marginalized peoples in Africa, Asia, and Latin America.” Since the demand for metals and minerals will increase substantially in a renewable-powered future . . . this intensification could exacerbate the existing consequences of extractive activities.

Among the connections between climate change and waste, O’Neill . . . highlights that “devices developed to reduce our carbon footprint, such as lithium batteries for hybrid and electric cars or solar panels[,] become potentially dangerous electronic waste at the end of their productive life.” The disposal of toxic waste has long perpetuated social injustice through the flows of waste to the Global South and to marginalized communities in the Global North . ..

While renewable energy is a more recent addition to financial portfolios, investments in the sector must be considered in light of our understanding of capital accumulation. As agricultural finance reveals, the concentration of control of corporate activity facilitates profit generation. For some climate activists, the promise of renewables rests on their ability not only to reduce emissions but also to provide distributed, democratized access to energy . . .But Burke and Stephens . . . caution that “renewable energy systems offer a possibility but not a certainty for more democratic energy futures.” Small-scale, distributed forms of energy are only highly profitable to institutional investors if control is consolidated somewhere in the financial chain. Renewable energy can be produced at the household or neighborhood level. However, such small-scale, localized production is unlikely to generate high returns for investors. For financial growth to be sustained and expanded by the renewable sector, production and trade in renewable energy technologies will need to be highly concentrated, and large asset management firms will likely drive those developments.

Based on the passage, we can infer that the author would be most supportive of which one of the following practices?

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 14

The question asks us to pick a choice that the author would be most supportive of. 1 goes out because the author in the last paragraph says that localised renewable energy systems is unlikely to generate high returns for investors. 2 can be definitely inferred because the author clearly says at the end of second last para that disposal of toxic waste has perpetuated social injustice. Thus 2 is the right choice. For many 3 might be a tempting choice, but it is beside the point. The author is not concerned with more environment friendly carbon based fuels. He is talking about renewable energy sources, and the social and financial costs behind it. The whole discussion in the passage is based on the premise that we have already taken the path low carbon based renewable energy path. So the suggestion in 3 is pointless. 4 goes out because the author is not favouring any study. He wants resolution to the problem, so he wants action.

This is a slightly difficult question. But 1 definitely supports the author. It must go out. We can find the evidence in the second paragraph. The second sentence of the last paragraph provides evidence for the 2nd choice. The third choice has already been inferred while solving the earlier question. It can be found in the last sentence of the second last para. 4 is the right answer because there is no reference for it in the passage. We have to mark the answer based on the evidence that we see in the passage.

Which one of the following statements, if false, could be seen as best supporting the arguments in the passage?

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 16

This is the easiest question of the passage. We have to first falsify the choice and then see whether it is supporting the arguments in the passage. Choice 4, when falsified, says that renewable energy systems have an environmental impact. If that is the case, the author’s arguments find support in the passage. Thus 4 is the right choice. 1 goes out because the author says in the passage that renewable energy systems are not as profitable as nonrenewable energy systems. The Last sentence of the first paragraph provides evidence for this. The profitability aspect has been discussed in the last paragraph of the passage. Thus it takes care of both 2 and 3, because if the profitability is low, it means that the expense is high, and therefore economically unsustainable. Thus all 1,2 and 3 support the author without being negated, whereas 4 supports the author only when it is negated

This is a pretty interesting question. The author says “renewable energy can be produced at the household or neighbourhood level...but such small scale localised production is unlikely to generate high returns for investors.” This is a double edged sword. 2 goes out because efficiency has not at all been discussed in the last paragraph. Corporate control is indeed discussed but not in reference to democratic distribution of energy. Thus 3 goes out. 1 goes out because renewable energy has been discussed as a single idea, without any forms and types. Thus 1 also is a distortion

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 20

This question is a difficult one, where two possible sequences might be correct. There is no doubt that 42 is one pair and 13 is the other. The point is which will come first 13 or 42. The official answer says 1342, though we believe that 4213 is just equally logical a sequence.

CAT 2020 Slot 2: Past Year Question Paper - Question 21

Five jumbled up sentences, related to a topic, are given below. Four of them can be put together to form a coherent paragraph. Identify the odd one out and key in the number of the sentence as your answer:

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 21

This is a question of moderate difficulty. 1 points at some truth. We must try to find the sentence that connects with 1. How can we monopolize and protect data? By having intellectual property rights. Thus 31 form a pair. 4 adds another idea to the story; it says “alongside the world of monopolised information (already discussed in 31), we have information as a social good, incapable of being owned. 5 concludes by saying that “information good are freely replicable....it can be copied and pasted infinitely”. In the light of intellectual property rights, and free information goods, 2 seems to be the odd one out.

CAT 2020 Slot 2: Past Year Question Paper - Question 22

The passage given below is followed by four alternate summaries. Choose the option that best captures the essence of the passage.

With the Treaty of Westphalia, the papacy had been confined to ecclesiastical functions, and the doctrine of sovereign equality reigned. What political theory could then explain the origin and justify the functions of secular political order? In his Leviathan, published in 1651, three years after the Peace of Westphalia, Thomas Hobbes provided such a theory. He imagined a “state of nature” in the past when the absence of authority produced a “war of all against all.” To escape such intolerable insecurity, he theorized, people delivered their rights to a sovereign power in return for the sovereign’s provision of security for all within the state’s border. The sovereign state’s monopoly on power was established as the only way to overcome the perpetual fear of violent death and war.

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 22

The passage has three important keywords: sovereign equality, sense of insecurity, and what was done to overcome that insecurity. The passage tells us that people delivered their rights to a sovereign power in return for the sovereign’s provision of security. This was the only way to overcome the fear of insecurity. After all there is a give and take happening, and therefore there is a transaction. Thus 1 is the best choice. 2 misses on the people’s sense of insecurity. 3 goes out because limiting the power of papacy is not the essence of the discussion. Choice 4 misses the idea of give and take, people give their rights to the sovereign in return for his protection. It misses the crucial word “transactional relationship”.

The four sentences (labelled 1, 2, 3, 4) below, when properly sequenced would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer:

1. It also has four movable auxiliary telescopes 1.8 m in diameter.
2. Completed in 2006, the Very Large Telescope (VLT) has four reflecting telescopes,8.2 m in diameter that can observe objects 4 billion times weaker than can normally be seen with the naked eye.
3. This configuration enables one to distinguish an astronaut on the Moon.
4. When these are combined with the large telescopes, they produce what is called interferometry: a simulation of the power of a mirror 16 m in diameter and the resolution of a telescope of 200 m.


Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 23

This is one of the easiest questions. 2 introduces the idea of VLT and mentions what it has. 1 comes as an addition and mentions the additional things that VLT has. 4 talks about what happens when these are combined. 3 is the result of that combination. Thus 2143 is the right sequence. A very easy question indeed!

CAT 2020 Slot 2: Past Year Question Paper - Question 24

The passage given below is followed by four alternate summaries. Choose the option that best captures the essence of the passage.

All humans make decisions based on one or a combination of two factors. This is either intuition or information. Decisions made through intuition are usually fast, people don’t even think about the problem. It is quite philosophical, meaning that someone who made a decision based on intuition will have difficulty explaining the reasoning behind it. The decision-maker would often utilize her senses in drawing conclusions, which again is based on some experience in the field of study. On the other side of the spectrum, we have decisions made based on information. These decisions are rational — it is based on facts and figures, which unfortunately also means that it can be quite slow. The decision-maker would frequently use reports, analyses, and indicators to form her conclusion. This methodology results in accurate, quantifiable decisions, meaning that a person can clearly explain the rationale behind it.

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 24

In the passage the author compares the two factors based on which humans make decisions. The first is intuition and the other is information. The author seems to be comparing the two without any preference. 1 goes out because it inaccurately says that “we choose intuition or information based on the time available”. Nothing of this sort has been given in the passage. Time in not the causative factor here. 2 says “it is better”. Since the author has not given any preference, it would be wrong to say which one is better. Thus 2 also goes out. 3 is the right summary, and captures the essence by stating that the difference is differential speed and ability to provide a rationale. 4 just focuses on intuition, and ignores the other factor entirely.

CAT 2020 Slot 2: Past Year Question Paper - Question 25

The passage given below is followed by four alternate summaries. Choose the option that best captures the essence of the passage.

The rural-urban continuum and the heterogeneity of urban settings pose an obvious challenge to identifying urban areas and measuring urbanization rates in a consistent way within and across countries. An objective methodology for distinguishing between urban and rural areas that is based on one or two metrics with fixed thresholds may not adequately capture the wide diversity of places. A richer combination of criteria would better describe the multifaceted nature of a city’s function and its environment, but the joint interpretation of these criteria may require an element of human judgment.

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 25

There are three important keywords in this paragraph: the challenge posed by rural-urban continuum, the objective methodology with one or two metrics may not be enough to capture the wide diversity, it may require an element of human judgement. 2 captures all the keywords succinctly. 1 misses the element of human judgement, 3 also misses on the same. 4 goes out because it is not about the judgment of objective methodology, but human judgement coming as an additional factor to aid the methodology.

The four sentences (labelled 1, 2, 3, 4) below, when properly sequenced would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer:

1. But the attention of the layman, not surprisingly, has been captured by the atom bomb, although there is at least a chance that it may never be used again.
2. Of all the changes introduced by man into the household of nature, [controlled]largescale nuclear fission is undoubtedly the most dangerous and most profound.
3. The danger to humanity created by the so-called peaceful uses of atomic energy may, however, be much greater.
4. The resultant ionizing radiation has become the most serious agent of pollution of the environment and the greatest threat to man’s survival on earth.


Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 26

This might a little tricky question, but without doubt 2 will open the paragraph. The resultant ionising radiation in 4 is a consequence of large scale nuclear fission mentioned in 2. Thus 24 form a pair. 4 and 1 are contrasting ideas, something that justifies the presence of the conjunction “but” in 1. The resultant ionising radiation has become the most serious agent of pollution... but the attention of the layman has been captured by the atom bomb....3 comes as the appropriate conclusion. 3 can’t come after 4 because both 4 and 3 talk nuclear fission, which does not justify the presence of the word “however” in 3. We use however to contrast two ideas, but both 4 and 3 talk of peaceful uses of atomic energy. Nuclear fission is used for purposes other than atomic bomb. Thus 2413 is the right sequence.

Twenty five coloured beads are to be arranged in a grid comprising of five rows and five columns. Each cell in the grid must contain exactly one bead. Each bead is coloured either Red, Blue or Green.

While arranging the beads along any of the five rows or along any of the five columns, the rules given below are to be followed:
1. Two adjacent beads along the same row or column are always of different colours.
2. There is at least one Green bead between any two Blue beads along the same row or column.
3. There is at least one Blue and at least one Green bead between any two Red beads along the same row or column.

Every unique, complete arrangement of twenty five beads is called a configuration.

The total number of possible configuration using beads of only two colours is:

As we need to use only two colours, in any row or column these two coloured beads will be
placed alternately like

So we cannot place Red coloured beads at position 1 or two as between any two Red beads there must at least two beads (at least one green and at least one Blue). Hence, we can use only Green and Blue coloured beads.

We can have two possible configurations:

2. There is at least one Green bead between any two Blue beads along the same row or column.
3. There is at least one Blue and at least one Green bead between any two Red beads along the same row or column.

Every unique, complete arrangement of twenty five beads is called a configuration.

What is the maximum possible number of Red beads that can appear in any configuration ?


Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 28

Between Any two Red beads there must be at least two Beads. So any Row or column there can be maximum two red beads. If we place two red beads in each row then two columns will have three red bead which cannot be accepted.

The above configuration is not correct.

So in the third row we will place only one Red bead at the middle of the third row. Also we will adjust other rows so that between any two Red beads there are at least two beads in any column.

So maximum 9 Red beads are possible in any configuration. At remaining places Green and Blue coloured beads can be placed in such way that all the conditions given are satisfied. There are multiple configurations are possible. One of the configurations is given as below.

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 29

To minimise number of Blue beads we need to maximise number of Red and Green beads. From the previous question solution, Maximum no. Red beads can be 9. The row in which has two red beads, we will place two green and one Blue bead additionally.

The row with only one red bead we will place two green and two blue beads additionally. So overall there will be minimum 6 Blue beads.

CAT 2020 Slot 2: Past Year Question Paper - Question 35

A shopping mall has a large basement parking lot with parking slots painted in it along a single row. These slots are quite narrow; a compact car can fit in a single slot but an SUV requires two slots. When a car arrives, the parking attendant guides the car to the first available slot from the beginning of the row into which the car can fit.

For our purpose, cars are numbered according to the order in which they arrive at the lot. For example, the first car to arrive is given a number 1, the second a number 2, and so on. This numbering does not indicate whether a car is a compact or an SUV. The configuration of a parking lot is a sequence of the car numbers in each slot. Each single vacant slot is represented by letter V.

For instance, suppose cars numbered 1 through 5 arrive and park, where cars 1, 3 and 5 are compact cars and 2 and 4 are SUVs. At this point, the parking lot would be described by the sequence 1, 2, 3, 4, 5. If cars 2 and 5 now vacate their slots, the parking lot would now be de8scribed as 1, V, V, 3, 4. If a compact car (numbered 6) arrives subsequently followed by an SUV (numbered 7), the parking lot would be described by the sequence 1, 6, V, 3, 4, 7.

Initially cars numbered 1, 2, 3, and 4 arrive among which 1 and 4 are SUVs while 2 and 3 are compact cars. Car 1 then leaves, followed by the arrivals of car 5 (a compact car) and car 6 (an SUV). Car 4 then leaves. Then car 7 (an SUV) and car 8 (a compact car) arrive. At this moment, which among the following numbered car is parked next to car 3?

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 35

The parking slots will be numbered as follows.

The cars that are parked next to car 3 are car 2 and car 7.

If a compact car (numbered 6) arrives subsequently followed by an SUV (numbered 7), the parking lot would be described by the sequence 1, 6, V, 3, 4, 7.

Suppose eight cars have arrived, of which two have left. Also suppose that car 4 is a compact and car 7 is an SUV. Which of the following is a POSSIBLE current configuration of the parking lot?

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 36

When cars 5 and 6 are present, car 7 cannot take a place between them. So , 5,7,6 is not
possible.
8,2,3, V, 5,6,7 is possible in the following sequence of arrival of cars.
I. Cars 1,2,3,4,5,6 and 7 arrive one after the other.
II. Car 1 leaves
III. Car 8 arrives and is parked in the slot vacated by car 1
IV. Car 4 leaves.
V. 2,3,7,5,6,8 is not possible as car 7 (SUV) cannot be parked in place of car 4 (compact)
while cars 3 and 5 are still parked. 8, 2, 3, V, 6,5,7 is not possible as car 6 cannot be between a vacant slot and to the left of car 5 for the following reasons.
If no slot is vacant when car 6 is arrived, it would have been parked to the right of car 5.
If car 4 (compact) left by the time car 6 arrives it would either be parked in the slot vacated by car 4 or to the right of car 5.

From the given arrangement it can be understood that cars 1, 2 and 3 arrived first and then cars 1 and 2 left before cars 4, 5 and 6 arrived. Now, there are four slots to the left of car 3. Hence, cars 1 and 2 are SUVs. Since three out of four slots are occupied by cars 4, 5 and 6, all these are compact cars. Whether car 3 is a compact car or an SUV, the given
arrangement is possible.

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 38

As cars 3 and 5 are still in their positions and that car 4 is not the first car to leave, at least one of cars 1 and 2 left before car 4. Let us consider the following cases. Both cars 1 and 2 left before car 4: In this case car 6, whether it is a compact car or an SUV, would have been parked in the parking lots vacated by cars 1 and 2. Hence, this case is not possible.

Only car 1 left before car 4: As car 6 is parked in the lot vacated by car 4, car 7 would have been parked in place of car 1. But the s lot vacated by car 1 is still vacant. Hence, this case is not possible.

Only 2 left before car 4: If the car 2 is an SUV, car 6 would have been parked in that lot. Hence, cars 2 and 7 are compact cars. Car 1 left after car 7 arrived.

The Humanities department of a college is planning to organize eight seminars, one for each of the eight doctoral students - A, B, C, D, E, F, G and H. Four of them are from Economics, three from Sociology and one from Anthropology department. Each student is guided by one among P, Q, R, S and T. Two students are guided by each of P, R and T, while one student is guided by each of Q and S. Each student is guided by a guide belonging to their department.

Each seminar is to be scheduled in one of four consecutive 30-minute slots starting at 9:00 am, 9:30 am, 10:00 am and 10:30 am on the same day. More than one seminars can be scheduled in a slot, provided the guide is free. Only three rooms are available and hence at the most three seminars can be scheduled in a slot. Students who are guided by the same guide must be scheduled in consecutive slots.

The following additional facts are also known.
1. Seminars by students from Economics are scheduled in each of the four slots.
2. A’s is the only seminar that is scheduled at 10:00 am. A is guided by R.

In an election several candidates contested for a constituency. In any constituency, the winning candidate was the one who polled the highest number of votes, the first runner up was the one who polled the second highest number of votes, the second runner up was the one who polled the third highest number of votes, and so on. There were no ties (in terms of number of votes polled by the candidates) in any of the constituencies in this election.

In an electoral system, a security deposit is the sum of money that a candidate is required to pay to the election commission before he or she is permitted to contest. Only the defeated candidates (i.e., one who is not the winning candidate) who fail to secure more than one sixth of the valid votes polled in the constituency, lose their security deposits.

The following table provides some incomplete information about votes polled in four constituencies: A, B, C and D, in this election.

The following additional facts are known:
1. The first runner up polled 10,000 more votes than the second runner up in constituency A.
2. None of the candidates who contested in constituency C lost their security deposit. The difference in votes polled by any pair of candidates in this constituency was at least 10,000.
3. The winning candidate in constituency D polled 5% of valid votes more than that of the first runner up. All the candidates who lost their security deposits while contesting for this constituency, put together, polled 35% of the valid votes.

What is the percentage of votes polled in total by all the candidates who lost their security deposits while contesting for constituency A?


Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 45

Total valid votes in A = 5,00,000 Minimum no of valid votes required to save the security
deposits 

As per 1st additional information ⇒ the gap between 1st and 2nd runners up is 10,000 So
the table for A⇒ total →5,00,000

Winner →2,75,000
1st runner up →55,000
2nd runner up →85,000
Total →4,55,000
The valid votes got by the other 7 candidates = 5,00,000 - 4,55,000
= 45,000

How many candidates who contested in constituency B lost their security deposit?


Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 46

Total valid votes in A=3,25,000

Minimum no of valid votes required to save the security deposits

We can see the winner himself/herself has got 48,750 no of votes which is less than 1/6th of the total votes.
∴ all of the candidates got less than 1/6th of the valid votes.
∴ security deposits will be forfeited for all of the candidates as winner is exempted from

In any constituency, the winning candidate was the one who polled the highest number of votes, the first runner up was the one who polled the second highest number of votes, the second runner up was the one who polled the third highest number of votes, and so on. There were no ties (in terms of number of votes polled by the candidates) in any of the constituencies in this election.

In an electoral system, a security deposit is the sum of money that a candidate is required to pay to the election commission before he or she is permitted to contest. Only the defeated candidates (i.e., one who is not the winning candidate) who fail to secure more than one sixth of the valid votes polled in the constituency, lose their security deposits.

The following table provides some incomplete information about votes polled in four constituencies: A, B, C and D, in this election.

The following additional facts are known:
1. The first runner up polled 10,000 more votes than the second runner up in constituency A.
2. None of the candidates who contested in constituency C lost their security deposit. The difference in votes polled by any pair of candidates in this constituency was at least 10,000.
3. The winning candidate in constituency D polled 5% of valid votes more than that of the first runner up. All the candidates who lost their security deposits while contesting for this constituency, put together, polled 35% of the valid votes.

How many candidates who contested in constituency B lost their security deposit?

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 47

As the additional information in condition (2)
The minimum difference in no of votes between any pair of candidates = 10,000 As there are 5 candidates in c, the possible distribution of valid is as follows.

Additional 30 votes can be distributed among them to maintain the gap at least 10,000. So the possible answer is 1,40,006

2. None of the candidates who contested in constituency C lost their security deposit. The difference in votes polled by any pair of candidates in this constituency was at least 10,000.
3. The winning candidate in constituency D polled 5% of valid votes more than that of the first runner up. All the candidates who lost their security deposits while contesting for this constituency, put together, polled 35% of the valid votes.

What was the number of valid votes polled in constituency D?

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 48

Let the no of valid votes → 100x
The table looks like the following:
Total votes →100x
Winner → 39,375
1st →37,500
2nd → 30,000
3rd → 10x
Total → 1,06,875
As the winner got 51 more than 1st runner up (as per 3 )
Total no of votes has to be more than

=1,10,208
∴ option (62,500) is ruled out.
To eliminate two more options, lets consider 1,50,000 to be the correct one [as one option is less than & the other one is the greater than this option]
∴100x = 1,50,000
Total →1,50,000
Winner →45,000
1st →37,500
2nd →30,000
3rd →15,000
Total →1,06,875
Minimum rates to save security deposits 

So we can see except 3 candidates all others have lost their security deposits.
Candidates who saved their security deposits = (100 -35)% = 65%[ as per 3rd additional
inform]
∴ 65% of 1,50,000 = 97,500
→ which is less than 1,12,500
∴ answer will be more than 1,50,000

The winning margin of a constituency is defined as the difference of votes polled by the winner and that of the first runner up. Which of the following CANNOT be the list of constituencies, in increasing order of winning margin?

Detailed Solution for CAT 2020 Slot 2: Past Year Question Paper - Question 49

Margins
A → 2,75,000 - 95,000 = 1,80,000
B →
C  → 1,50,000 -1, 40,000 =10,000
D → 39,375 - 37,500 =1,875
Clearly the margin in C is more than that of D. So clearly the sequence B , C , D , A is not
possible.
