UGC NET Paper 1 Mock Test - 5 - UGC NET MCQ

The correct response is to establish a water treatment infrastructure to remove nitrates.

Key Points

While awareness campaigns and healthcare training are important, addressing the root cause of exposure through water treatment is the most sustainable and effective prevention strategy.
Investing in infrastructure like filter systems or alternative water sources can eliminate nitrate contamination at its source and protect entire communities.
Advanced diagnostic equipment and specialized treatments, though valuable, might not be readily accessible or affordable in resource-limited settings.
Therefore, option (3) prioritizes long-term prevention and reduces reliance on individual medical interventions.

Additional Information

• Blue Baby Syndrome, also known as methemoglobinemia, is a condition where the blood's ability to carry oxygen is impaired. This can lead to a bluish skin discoloration, particularly around the lips and fingertips, hence the name "blue baby."
• However, it's important to remember that this condition isn't always visible at birth and the bluish hue can vary in intensity. Let's explore the causes and impacts of Blue Baby Syndrome:

Causes:

• Nitrates: This is the most common cause in developing countries, particularly due to exposure to nitrate-contaminated water sources. Nitrates react with hemoglobin, the oxygen-carrying protein in red blood cells, converting it to methemoglobin, which cannot effectively transport oxygen.
• Genetic mutations: Certain inherited genetic variations can affect the body's ability to produce or regulate methemoglobin levels, leading to the syndrome.
• Certain medications: Some medications, like methemoglobin-inducing anesthetics, can temporarily cause this condition.
• Other factors: Rare conditions like exposure to certain chemicals or toxins can also trigger Blue Baby Syndrome.

Impacts:

• Oxygen deprivation: The main concern with methemoglobinemia is the reduced oxygen delivery to tissues and organs. This can lead to symptoms like fatigue, shortness of breath, dizziness, and even seizures in severe cases.
• Delayed development: In infants and young children, oxygen deprivation can affect growth and development, highlighting the importance of early diagnosis and treatment.

Diagnosis and Treatment:

Blood tests can confirm the presence of methemoglobin and determine its cause.
Treatment depends on the severity of the condition and its underlying cause. In mild cases, simply removing the source of exposure (e.g., switching to a clean water source) might be sufficient.
For moderate to severe cases, medications like methylene blue can help convert methemoglobin back to hemoglobin, restoring oxygen-carrying capacity.
Prevention:

• Ensuring access to clean drinking water in vulnerable communities can significantly reduce nitrate-related cases of Blue Baby Syndrome.
• Genetic counseling can be helpful for families with a history of the condition to understand potential risks and plan accordingly.
• Raising awareness about the early symptoms and seeking prompt medical attention is crucial for timely diagnosis and effective management.

The correct answer is A, B, C and D only

An independent media means that no one should control and influence its coverage of news.

• No one should tell the media what can be included and what should not be included in a news story.
• An independent media is important in a democracy.

Important Points However, the reality is that media is far from independent.

• The control that the government has on the media. When the government prevents either a news item, or scenes from a movie, or the lyrics of a song from being shared with the larger public, this is referred to as censorship.
• There have been periods in Indian history when the government censored the media. The worst of these was the Emergency between 1975-1977.

Thus, we can say that between the period 1975-1977 media was censored in India.

- Statement A: All things are non-eternal, because they are knowable.
- This statement is based on the principle that anything that can be perceived or known is subject to change, and hence, cannot be eternal. This is a straightforward application of the Nyaya school's logic, without a direct counterbalance within the statement itself.
- Hence, Statement A is incorrect for the context of the question as it doesn't involve a counterbalancing reason.
- Statement B: Fire is cold because it is a substance.
- This statement presents a reason that is directly counterbalanced by common knowledge or empirical evidence. According to the Nyaya school, a substance can have various qualities, and being a substance does not necessarily make fire cold, as fire is empirically known to be hot.
- Hence, Statement B is correct because the reason provided is directly counterbalanced by the known quality of fire.
- Statement C: Sound is eternal because it is produced.
- This presents a reason that is counterintuitive or counterbalanced by the Nyaya school's understanding that anything produced is non-eternal. The Nyaya philosophy posits that anything that has a beginning (i.e., is produced) must also have an end, and thus cannot be eternal.
- Hence, Statement C is correct as the reason given is counterbalanced by the philosophical understanding of production and eternity.
- Statement D: Sound is a quality, because it is visible.
- This statement's reason is flawed or counterbalanced by the basic understanding that sound is not a visible phenomenon but an auditory one. The visibility of an object is not a quality that can be attributed to sound, making the reason provided inherently counterbalanced by the nature of sound itself.
- Hence, Statement D is incorrect for the context of the question since it doesn't involve a counterbalancing reason based on Nyaya logic but rather presents a fundamentally flawed reason.
- Conclusion:
- The correct answer is option 1, which includes Statements B and C. Both of these statements present reasons that are directly counterbalanced by another reason or understanding, fitting the criteria set by the question based on classical Indian school of logic (Nyay).

The correct answer is All organic matters in water.

Key Points

• Chemical Oxygen Demand (COD) is a measure of the amount of oxygen that is required to chemically oxidize the organic matter present in water. It is expressed in milligrams of oxygen per liter (mg/L).
• COD is a measure of the total amount of oxidizable material in water, including both biodegradable and non-biodegradable substances. Biodegradable substances are those that can be broken down by bacteria, while non-biodegradable substances cannot be broken down by bacteria.
• COD is an important parameter in water quality testing because it can be used to assess the level of pollution in water. High COD levels indicate that the water is polluted with organic matter, which can be harmful to aquatic life.

Additional Information

• COD is also used to monitor the efficiency of wastewater treatment plants. A high COD level in the effluent from a wastewater treatment plant indicates that the plant is not removing enough of the organic matter from the wastewater.
• The COD test is conducted by adding a strong oxidizing agent, such as potassium dichromate, to a sample of water. The amount of oxygen that is consumed by the oxidizing agent is then measured. The higher the COD value, the more organic matter is present in the water.

Hence the correct answer is All organic matters in water.

The correct solution is "Ad populum"
Important Point
A Fallacy is the invalid or otherwise faulty reasoning, or "wrong moves" in the construction of an argument. A fallacious argument may be deceptive by appearing to be better than it really is.
A fallacy can be of two types:

• Formal fallacy: arguments that have invalid structure or form.
• Informal fallacy: arguments that have incorrect or irrelevant premises.

In the above question, the fallacies given are informal fallacies.
Key Points
Ad Populum:

• Ad Populum is also known as Argumentum ad Populum (Appeal to people/emotions) Appealing to popularity
• It is a fallacious argument that concludes that a proposition must be true because many or most people believe it, often encapsulated as If many believe so, it is so.
• For example, This girl should come first because she is cute and beautiful.

Hence, option 3 is the correct answer.
Additional Information

1. Ad Hominem is also known as Argumentum ad hominem (argument against the person): This fallacy occurs when, instead of addressing someone's argument or position, you irrelevantly attack the person or some aspect of the person who is making the argument. It's an insult used as if it were an argument or evidence in support of a conclusion. For example:
   • Ravi teaches youth to speak the truth but his son lies.
   • Mr. X is wrong in what he said because he is undisciplined by nature
2. Ad hoc- An ad hoc argument isn't really a logical fallacy, but it is a fallacious rhetorical strategy that is common and often hard to spot. It occurs when someone's claim is threatened with counter-evidence, so they come up with a rationale to dismiss the counter-evidence, hoping to protect their original claim.
3. Ad misericordiam- (Appeal to pity) in which someone tries to win support for an argument or idea by exploiting his or her opponent's feelings of pity or guilt. It is a specific kind of appeal to emotion. For example, you should not find the defendant guilty of murder, since it would break his poor mother's heart to see him sent to jail"

The Correct answer is B, C, and D

Key Points

• Robert Craig has identified seven traditions within communication theory, acknowledging the complexity of the communication process and the multitude of definitions associated with it.
• These traditions are categorized as follows:
  • Cybernetic
  • Socio-psychological
  • Socio-cultural
  • Critical
  • Rhetorical
  • Phenomenological
  • Semiotic
• Cybernetic tradition:
  • ​The cybernetic tradition views communication as an information process centered on systems, whether they be individuals or organizations, and the channels employed for message transmission.
  • In this perspective, communication is inherently goal-oriented.
  • The sender begins with a specific goal, crafting a message and selecting a communication channel for transmission.
  • However, what the receiver initially decodes may differ from the sender's intended message.
• Socio-psychological tradition:
  • ​The socio-psychological tradition perceives communication as interpersonal interaction, falling within the behavioral approach.
  • It emphasizes cause-and-effect relationships in communication, particularly in terms of stimuli and reactions.
  • Rooted in psychology and sociology, this tradition focuses on expression, interaction, and influence.
  • Notably objective, theorists within the socio-psychological tradition approach communication with an objective mindset.
• Socio-cultural tradition:
  • ​The socio-cultural tradition views communication as a symbolic process integral to the reproduction or production of social order.
  • Emphasizing context, culture, and social practices, it shifts focus from individual or group responses to stimuli to the broader societal level.
  • Here, significance is placed on how society operates, with everyday routines and interactions contributing to the creation of shared meanings and understandings.
  • Through communication, individuals engage in dialogue, shaping collective interpretations of the world and specific situations.
• Critical tradition:
  • ​In the critical tradition, language and ideology take center stage, with scholars asserting that control over language confers dominance in society. Ideology holds particular significance, being deeply embedded and perpetuated through various tools and media forms.
  • Critical scholars, therefore, direct their attention to media, a potent mass communication tool that disseminates ideology to wider audiences.
  • Ultimately, this ideology, conveyed through media, becomes an integral part of the broader discourse.
• Rhetorical tradition:
  • In public presentations, the use of public speaking involves employing the rhetorical tradition, which traces its roots back to ancient Greece.
  • This tradition encompasses the development of crucial techniques and guidelines for structuring public speeches.
  • Central to this approach is the art of rhetoric, focusing on the ways verbal and nonverbal communication can be harnessed to influence audiences.
• Phenomenological tradition:
  • The phenomenological tradition emphasizes that the communication process is subject to varying perceptions among individuals.
  • It focuses on communication as a shared experience through dialogue, considering the diverse perspectives and interpretations within a given context.
  • Exploring how minority groups comprehend reality and engage in communication provides insights into the outcomes of interpersonal interactions.
• Semiotic tradition:
  • The semiotic tradition revolves around communication as the sharing of meaning through a system of signs and symbols.
  • In conversations between individuals who share a strong familiarity, outsiders may struggle to fully comprehend the interaction and might misinterpret it.
  • This is because the involved parties possess a set of established terms and unique jargon for specific situations and past experiences.
  • It becomes crucial for observers to discern the signs and symbols within the interaction to understand the representation and transmission of meaning.

• Mead's theory is that begins their understanding of the social world through play and game.
• Mead believes that people develop self-images through interactions with other people means he was basically related to socialization.
• Urie Bronfenbrenner and G.H. mead has relied on socialization. He tells that altering the perspective of developmental psychology by calling attention to the many additional environmental and societal influences which impacted child development means he is also related to socialization.

• Microsystem is related to imitating the environment.
• Mesosystem is related to the connection.
• Ecosystem is related to the indirect event.
• Macrosystem, this is related to social and cultural values.
• Chronosystem this is related to changes over time.

Calculation
The total production of wheat in the years 2022 and 2023 from Bihar is 1200
10% → 1200
1% → 120
The total production of wheat in the years 2022, 2023 and 2024 from Rajasthan = 3 × 900 = 2700
The total production of wheat in the year 2022 from Rajasthan = 20% × 11/20 = 11%
11% → 11 × 120 = 1320
The total production of wheat in the year 2023 from Rajasthan = 20% × 9/20 = 9%
9% → 9 × 120 = 1080
The total production of wheat in the year 2024 from Rajasthan = 2700 - (1320 + 1080) = 300
25% of the total production of wheat in the year 2024 from Rajasthan = 300 × 1/4 = 75
The answer is 75.

The answer is 60% less.

Learning is modification of behavior through experience.

• It involves acquisition of knowledge, habits and attitudes through experience and practice.

Key PointsLet's evaluate the statements:

Statement I: A child learns more if taught by computer only.

• This statement is generally not correct. While computers can be valuable educational tools, learning exclusively through a computer may not be as effective as a blended approach that includes various methods and interactions.
• Effective learning often requires a combination of methods, including personal interaction, hands-on activities, and direct instruction.

Statement II: A child learns more if taught by the child-centred method.

• This statement is generally correct. The child-centered method focuses on the needs, interests, and abilities of the child, promoting active participation and engagement in the learning process.
• Research suggests that this approach can lead to better learning outcomes as it supports individualized learning and fosters a deeper understanding.

Therefore, the correct option is only statement II is correct.

The correct answer is Varied connotations
Important PointsSemantic barrier refers to the challenges that arise in communication due to differences in the interpretation and understanding of words, symbols, and signs.

• It occurs when the connotations, or the emotional and cultural associations, attached to words vary among individuals or groups.
• These variations can lead to misunderstandings, misinterpretations, and ineffective communication.
• While words may have a denotative meaning, which is the literal or dictionary definition of a word, their connotations can differ based on personal experiences, cultural backgrounds, and individual interpretations.
• Different people may associate different emotions, values, or ideas with the same word, leading to semantic barriers in communication.

Understanding the varied connotations associated with words and symbols is crucial for effective communication, especially in cross-cultural or diverse settings.

• Communicators need to be aware of the potential differences in interpretation and actively strive for clarity and mutual understanding to overcome semantic barriers.

The Correct Answer is 1986.

Key Points

• The Environment (Protection) Act of India was enacted in 1986 with the objective of providing for the protection and improvement of the environment.
• The act was enacted by the Parliament of India under Article 253 of the Indian Constitution.
• The Act empowers the Central Government to establish authorities with the mandate of preventing environmental pollution in all its forms.
• Article 253 deals with Legislation for giving effect to international agreements

The correct answer is 'The generic advice of drinking eight glasses of water a day is an absolute requirement for everyone to maintain hydration'.

Key Points

• The passage specifically states that the advice to drink eight glasses of water a day should not be strictly adhered to, as individual hydration needs can vary based on several factors, including physical activity levels, climatic conditions, age, and health conditions.
• The statement contradicts the information provided in the passage, as such it's the incorrect one among the options provided.
• The other options accurately summarize the essential role of water, the variable water requirements of people based on their lifestyle and location, and the signs of dehydration, as mentioned in the text.

Hence, the correct answer is Option 2.

The correct answer is 'Heat Stroke, Kidney Failure, or Seizures'.

Key Points

• The passage explicitly outlines that severe dehydration can result in more grave consequences, including heat stroke, kidney failure, or even seizures.
• Although headaches and difficulties in concentration are mentioned in the passage, they are consequences of mild dehydration, not severe. Similarly, thirst and dark urine color are signs of dehydration, but they are not specifically associated with severe dehydration.
• So, the other options, while referring to parts of the text, are not accurately representing the health issues related to severe dehydration.

Therefore, the correct answer is Option 2.

The correct answer is 'The color of their skin'.

Key Points

• The passage does not mention skin color as a factor impacting an individual's hydration needs.
• Age, climate, and the level of physical activity are stated as significant influences on hydration needs. The statement about the color of skin being a factor in hydration needs is not supported by the information in the passage.
• Thus, the other options are incorrect as they are included in the passage as factors influencing hydration needs.

So, the right response is Option 3.

The correct answer is 'Statement I, III, and IV are correct'.

Key Points

• Statement I is true according to the passage. The passage asserts that water makes up about 60% of the human body and is essential for bodily functions.
• Statement II is false. The passage specifically mentions that dehydration can lead to both minor and severe health problems. It states that severe dehydration can cause heat stroke, kidney failure, and even seizures.
• Statement III aligns with the information given in the passage, which mentions that factors like climate, physical activity levels, age, and individual health conditions can significantly influence the amount of water a person needs.
• Statement IV is also true as it accurately captures the signs of dehydration stated in the passage - feeling thirsty, having darker urine color, experiencing a dry mouth, and feeling fatigue.

Therefore, the correct answer is Option 3.

The factors that affect mediated persuasion are:

• The source's credibility: This refers to the extent to which the source of the message is perceived as being believable and trustworthy.
• The message's content: This refers to the information that is being communicated in the message.
• The message's presentation: This refers to the way that the message is delivered, such as the use of language, images, and music.
• The audience's characteristics: This refers to the characteristics of the people who are receiving the message, such as their age, gender, education level, and cultural background.
• The audience's characteristics are not a factor that affects mediated persuasion.
• This is because the message is the same for everyone, regardless of their individual characteristics.
• However, the audience's characteristics can affect how the message is received and interpreted.
• For example, a message that is targeted at young people may be more effective than a message that is targeted at older people.

So, the answer choices that include the audience's characteristics are incorrect. The correct answer choice is the one that includes the source's credibility, the message's content, and the message's presentation.

Here is an explanation of the answer choices:

• The source's credibility: A credible source is more likely to persuade people than a source that is not credible. This is because people are more likely to believe information that comes from a source that they trust.
• The message's content: The content of the message is also important. A message that is relevant to the audience and that is presented in a clear and concise way is more likely to be persuasive.
• The message's presentation: The way that the message is presented can also affect its persuasiveness. A message that is presented in a way that is interesting and engaging is more likely to be persuasive than a message that is presented in a boring and monotonous way.

Art Education is a primary pathway to learning, a journey of discovery of the meaning of teaching for aesthetic experience. Art is an expression of ideas created by human imagination, skill, and invention.

• It is a very important aspect of school education as it helps in developing the overall personality of a child.
• It helps the students to perform better in academics and to develop their thinking potential.

Key Points
Importance of art education at the elementary level:

• It enhances the level of self-analysis, self-esteem, and also self-discipline. Such children stay more motivated and cooperate more readily than the others.
• Art allows the children to develop their own free expression of what they are and how they feel as it allows them to learn in a more creative way than structured lessons.
• It also facilitates learning, logical thinking among the students and develops their practical aptitude by giving them real and practical experiences.
• For example, "Home Sweet Home" was the concept of the day. Children were told to make a home. Most of the children had brought their own material to make a house. Lots of ideas were coming up from huts to bungalows, to stilt houses with sticks, to igloos with cotton.
• So, the children will perform and learn about art and its various forms. It will enhance their learning with practicality.

Hence, it is concluded that art education at the elementary level in schools enhances learning by giving a practical experience.

Pramanas

Knowledge can be valid or invalid. Valid knowledge is known as Prama and non-valid knowledge is called Aprama. Pramana is valid means of knowledge and serves as one of the core concepts in Indian Epistemology. It is a theory of knowledge and encompasses one or more reliable and valid means by which human beings gain accurate and true knowledge.

Key Points While the number of pramanas varies widely from system to system, many ancient and medieval Indian texts identify six pramanas as the correct means of accurate knowledge and truth. The six pramanas are perception, inference, comparison, postulation, non-apprehension, and testimony. Different schools of Indian thoughts accept or reject different ones of these methods, Jainisn admits Perception, Inference, and testimony.

• Inference ( Anumana)

the term anumana means after knowledge i.e. knowledge that follows other knowledge. Literally, the meaning of Inference is to observe uniformity between two things. It is mediated and indirectly arranged through the medium of some mark which is called 'hetu' and bears the relation of invariable concomitance with the observed feature. the basis of the inference is invariable concomitance.

• Perception ( Pratyaksha )

Perception enables a person to have correct cognitions of the world through the senses. Perception is of two kinds, direct perception (anubhava) and remembered perception (smiriti). Some schools make a further distinction between indiscriminate perception(nirvikalpa), in which the object is perceived without its distinguishing features, and discriminate perception (savikalpa), in which the distinguishing features are both observed and recognized.

• Testimony ( sabda )

Sabda is defined as the statement of a trustworthy person and consists in understanding its meaning. It is based on authoritative statements. Testimony is of two kinds- Vaidika and Laukika. The vaidika testimony is perfect and infallible because the Vedas are spoken by God. Laukika testimony is the words of human beings who are liable to error.

Thus, option 3 is correct.

Additional Information

• Postulation ( Arthapati )

Arthapati is the assumption of an unperceived fact in order to reconcile two apparently inconsistent perceived facts. When a known fact can not be accounted for without another fact, we have to postulate(hypothesise) the existence of a third fact.

• Comparison (Upamana)

It is knowledge derived from similarity. It has been defined as the knowledge of the relation between word and its denotation.

• Non-appherension (Anupalabdhi)

It is the immediate knowledge of the non-existence of object.

Hence, we can conclude that Jainism admits Perception, Inference, and Testimony are the sources of knowledge.

• The United Nations Framework Convention on Climate Change (UNFCCC) is focused chiefly on addressing global warming and the resulting climate changes.
• Its key objectives include:
• Stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.
• Assisting developing countries to implement practices to mitigate climate change and adapt to its adverse effects.

Therefore, the correct answer is A and D only.

The psychological barrier of communication is the influence of the psychological state of the communicators (sender and receiver) which creates an obstacle for effective communication.

Important PointsSome psychological barriers to communication are as follows-

• Disinterest- When a person's mind is distracted or preoccupied with other things, he or she is unable to form proper messages, listen to what others say, interpret the message as needed, and provide appropriate feedback.
• Inattention- Indifference and lack of interest create barriers to communication, resulting in lower communication quality. The intended message is either not received at all or is incomplete and, worse, incorrectly understood.
• Prejudice- This type of prejudice is a barrier to effective listening because when a person is judged based on his or her identity or ideas, one usually stops listening actively and/or ethically. And shows prejudice in one's listening in a variety of ways, some more obvious than others.
• Emotions- Emotional issues, whether within an individual or between individuals, can directly impact thinking and communication skills. Fear, anxiety, anger and other common emotions can and do hamper how you relay your messages to others as well as interpret their messages to you.

Additional InformationNoise is one of the most common communication barriers. It is any persistent or random disturbance that reduces, obscures or confuses the clarity of a message. Physical barriers are closely related to noise as they can obstruct the communication transmission process. Invisibility - This is a physical communication barrier as invisibility can lead to distorted messages because the sender and the receiver cannot physically see each other. Therefore, the correct answer is options (C), (D) and (E) only.

• The global education development agenda reflected in Goal 4 (SDG4) of the 2030 Agenda for Sustainable Development, adopted by India in 2015 - seeks to “ensure inclusive and equitable quality education and promote lifelong learning opportunities for all” by 2030.
• Such a lofty goal will require the entire education system to be reconfigured to support and foster learning so that all of the critical targets and goals (SDGs) of the 2030 Agenda for Sustainable Development can be achieved.

Additional Information Sustainable Development Goal 4: Quality Education

• Achieving inclusive and quality education for all reaffirms the belief that education is one of the most powerful and proven vehicles for sustainable development.
• This goal ensures that all girls and boys complete free primary and secondary schooling by 2030.
• It also aims to provide equal access to affordable vocational training, to eliminate gender and wealth disparities, and achieve universal access to quality higher education.

Important Points
Presentation- A presentation is a verbal means of communication. A presentation is a formal talk to one or more people in which ideas or information are "presented" in a clear, structured manner. All presentations have the same goal: to inform, train, persuade, or sell.
An attention grabber is a tool used at the very beginning of a presentation with the intention of engaging one's audience.
Additional Information

Therefore, statement 1 is false as Presentation is a verbal means of communication as it uses words and signs. Whereas statement 2 Different components of the presentation that attract the attention of the audience are Attention grabbers is true.

The correct answer is A flat-plate solar collector absorbs sunlight from all directions, while a concentrating solar collector focuses sunlight onto a smaller area.
Key Points

A flat-plate solar collector consists of a flat, rectangular or square plate that absorbs sunlight over its entire surface area.

• It is typically covered with a transparent glass or plastic cover to minimize heat loss.
• The absorbed sunlight heats a fluid, such as water or air, flowing through pipes or channels within the collector.
• Flat-plate solar collectors are commonly used for applications such as domestic hot water heating and space heating.
• A concentrating solar collector uses mirrors or lenses to concentrate sunlight onto a smaller area.
• By focusing sunlight, a concentrating solar collector can achieve higher temperatures than a flat-plate collector.
• The concentrated sunlight is directed onto a receiver, which absorbs the sunlight and transfers the heat to a fluid or uses it to generate electricity.
• Concentrating solar collectors are often used in utility-scale solar power plants and for applications requiring high-temperature heat, such as solar furnaces or solar thermal power generation.

Therefore, the primary difference between a flat-plate solar collector and a concentrating solar collector lies in how they handle sunlight. A flat-plate collector absorbs sunlight from all directions, while a concentrating collector focuses sunlight onto a smaller area, allowing for higher temperatures and more concentrated energy output
