UGC NET Paper 1: Held on 5th Mar 2023 Shift 1 (Previous Year Paper)

Statement I is false but Statement II is true.

Key Points

Statement I: The objective of the memory level of teaching is to develop rational and critical thinking among students.

Explanation: The memory level of teaching focuses on rote learning, memorization, and recall of information rather than developing critical thinking skills.

• It is a lower level of learning that emphasizes on acquiring knowledge rather than applying it or analyzing it.

Thus statement I is false. 

Statement II: The objective of the reflective level of teaching is the ability to develop independent thinking and decision making among students.

Explanation:  The reflective level of teaching focuses on encouraging students to think deeply about the subject matter, analyze it, and make connections between different ideas.

• It promotes independent thinking, problem-solving skills, and decision-making abilities, which are essential for success in both academic and professional life.
• At this level, students are expected to use critical thinking skills to evaluate information, synthesize ideas, and develop their own viewpoints.

Thus Statement II is true.

Teacher-centered classroom management puts the teacher at the center of the classroom as the primary authority figure.

Key PointsExplanation:

• Discipline coming from self is a characteristic of student-centered classroom management, not teacher-centered.
• The teacher is the sole leader in a teacher-centered classroom, which means that they are in charge of setting the rules and expectations for the class.
• In teacher-centered classroom management, students are not facilitators for the operations of the classroom. Instead, the teacher is responsible for all aspects of classroom management.
• Students are allowed limited responsibilities in a teacher-centered classroom. This means that they have less autonomy and decision-making power than they would in a student-centered classroom.
• Therefore, the characteristics of teacher-centered classroom management include the teacher being the sole leader and students having limited responsibilities.

Conclusion: The most appropriate answer is B and D.

Learning to learn is a form of transfer in which an individual learns how to learn more effectively.

Key Points

• In the given scenario, the person has developed the ability to solve linear equations more efficiently by practicing them repeatedly over a number of days.
• This has led to an improvement in both the speed and accuracy of their work.
• The person has not only acquired new knowledge and skills but also developed a more effective approach to learning and problem-solving.
• This ability to learn and adapt to new situations is an important aspect of transfer learning and can be applied to other areas of study and work as well.

Additional Information 

• Generalization: The process of drawing a general conclusion based on specific observations or experiences.
• Transposition: The ability to transfer or apply knowledge or skills learned in one context to a new or different context.
• Identification: The process of recognizing or associating a particular person, object, or concept based on specific characteristics or features.

Ethics in research refers to the principles of moral behavior and conduct that researchers are expected to uphold in order to ensure the protection of human subjects and the integrity of scientific inquiry.

Key PointsExplanation:

• Plagiarism involves using someone else's work or ideas without giving them credit, which is a form of intellectual theft and violates ethical standards in research.
• Coercion involves using force or threats to obtain research participation, which is a violation of the ethical principle of voluntary participation.
• Breach of confidentiality occurs when a researcher discloses identifiable information about participants without their consent, which is a violation of the ethical principle of confidentiality.
• Beneficence is an ethical principle that requires researchers to maximize benefits and minimize harms to participants in their research, but it is not an ethical problem itself.
• Fidelity is an ethical principle that requires researchers to be truthful and keep promises made to participants, but it is not an ethical problem itself.

Therefore, the ethical problems in research include plagiarism, coercion, and breach of confidentiality.

Conclusion: The correct answers are A, B, and C.

It is important to take precautions when using online information because not all sources are reliable.

 Key Points

 

• To ensure the accuracy and credibility of the information, one should check the home page or 'About us' section of the website to verify the source and author.
• Additionally, one should not trust information without a date as it may be outdated or irrelevant.
• Finally, it is important to remember that the institution that owns the website may not always be trustworthy, so one should exercise caution and use critical thinking when evaluating online information.
• Thus, when using online information, it is important to take precautions to ensure that the information is accurate and credible.

The correct answers are C, D, and E.

Logic: Numbers are increasing and decreasing alternatively by the square of the numbers starting from 2.

Hence, the missing term is 98.

Logic: Code for the word is sum of the positional values of opposite alphabet of the letters.

C → X (Opposite alphabet) = 24

O → L (Opposite alphabet) = 12

M → N (Opposite alphabet) = 14

E → V (Opposite alphabet) = 22

So, the code for COME;

⇒ 24 + 12 + 14 + 22

⇒ 72

Hence, the correct answer is "72".

Scientific inquiry is a systematic approach to understanding the natural world that involves observing, questioning, testing, and analyzing data to generate knowledge that is based on evidence.

Key Points

• The key aspect of scientific knowledge is that it is replicable and verifiable.
• This means that the methods and results of scientific investigations can be independently confirmed by other scientists using the same methods and tools.
• This is what gives scientific knowledge its reliability and credibility.
• In contrast, the knowledge that is not scientific may be based on personal beliefs, cultural traditions, or untested assumptions.
• While these types of knowledge may have value in certain contexts, they are not considered scientific because they cannot be tested and verified using scientific methods.

To summarize, when knowledge becomes scientific, it means that it has been systematically tested and verified using scientific methods, and can be replicated by other scientists. This makes scientific knowledge reliable and credible and allows us to build on it to generate new insights and discoveries.

Additional Information

• Humanistic refers to a psychological approach that emphasizes the inherent worth and dignity of human beings, and the importance of personal growth and self-actualization.
• Impressionistic refers to a style of art that captures the essence or feeling of a subject rather than providing a realistic representation.
• Subjective refers to an individual's personal perspective, based on their opinions, feelings, or experiences, rather than objective facts or evidence.

The interview method is a research technique used to gather information from individuals by asking them a series of questions.

Key Points

Explanation:

• Ethical behavior is a critical criterion for a successful interviewer.
• This includes ensuring the privacy and confidentiality of the interviewee and treating them with respect and fairness.
• Open-mindedness is essential for successful interviewers as they need to be able to listen to the interviewee's perspective without judgment and remain flexible in their approach.
• Being gentle and sensitive to the interviewee's feelings and emotions is necessary for creating a comfortable and safe environment for the interviewee to share their thoughts and experiences.
• A balanced approach is critical in successful interviewing. This means being able to ask relevant and insightful questions while also allowing the interviewee to express their thoughts and feelings fully.
• Rigid and harsh comments are not appropriate for a successful interviewer as they can intimidate and discourage the interviewee from sharing their views and experiences.

Therefore, the criteria of a successful interviewer include ethical behavior, open-mindedness, gentle and sensitive approach, and a balanced approach.

Conclusion: The most appropriate answer is A, B, C, and D.

Statement I is correct but Statement II is incorrect.

Key PointsStatement - I: For open-ended questions, respondents can produce their own answers without any restriction of length.

• Open-ended questions are questions that allow respondents to provide their own answers without any predefined set of responses.
• These questions do not restrict the length or type of response. Respondents are free to provide as much detail or as little as they wish, and their responses may be more informative and reveal more insight than closed-ended questions.

Thus, statement I is correct.

Statement - II: The memory phenomenon of telescoping is not an issue in survey research.

• Telescoping is a memory phenomenon where respondents remember events as having occurred more recently than they actually did.
• It is a common issue in survey research, particularly when asking respondents to recall past events.
• However, statement II is incorrect as telescoping can be a significant issue in survey research, especially in studies that rely on accurate and precise recall of past events.
• The phenomenon can lead to inaccuracies and distortions in the data collected, affecting the overall quality of the research.

Thus, statement II is incorrect.

According to the given directions,

• He walks 20 meters in the west direction

• then turns right and walks 30 meters

• Thereafter he walks 10 meters in the east direction

The aerial distance between start point and end point is AC,

(AC)² = (AB)² + (BC)²

(AC)² = (10)² + (30)² 

AC = √(10)² + (30)²

AC = √100 + 900

AC = √1000

AC = 10√10 m

Hence, the correct answer is 10√10 m.

Preparing family tree by using these symbols given below:

• A is the son of B, but B is not the father of A.

which means B is the female member and the mother of A.

So, family tree is as follows;

Hence, the correct answer is "mother".

Let the number of Peacocks in the forest is x, then number of tigers = 90 - x

According to the question,

x × 2 + 4(90 - x) = 240

⇒ 2x + 360 - 4x =240

⇒ 2x = 120

⇒ x = 60

∴ The number of Peacocks in the forest = 60

And number of tigers in the forest = 90 - 60 = 30.

A research paper is a written document that presents the findings of a study or investigation on a particular topic.

Key Points

• Peer review is a process of evaluation of a research paper, article, or manuscript by experts in the same field of study to determine its quality, accuracy, and validity before publication or presentation at a conference.
• The experts, also known as peers or referees, review the paper to ensure that it meets the standards of the academic community and provides valuable contributions to the field.
• The peer review process typically involves an initial screening of the paper by the editor or program committee, followed by a detailed evaluation by two or more experts in the field.
• The reviewers provide feedback and comments on the strengths and weaknesses of the paper, including suggestions for improvement or clarification.
• The author is given the opportunity to revise the paper based on the feedback before resubmission.
• Peer review is an essential step in the academic publishing process as it helps to maintain the quality and integrity of research and ensures that only valid and accurate information is published.

Thus, a research paper evaluated by other experts either for publication or presentation at a conference is considered to have undergone peer review.

A message beneath a message, or an underlying meaning that is not explicitly stated, is often referred to as subtext.

Key Points

• Subtext is the hidden or implied message that is conveyed through tone, context, or nonverbal cues, and is often influenced by the speaker's intentions, emotions, or beliefs.
• For example, a person may say "I'm fine" when asked how they are feeling, but their tone of voice and body language may suggest otherwise, revealing a subtext of sadness, frustration, or anger. Subtext can also be used in literature, film, or other forms of media to convey deeper meaning and create a more nuanced or complex message.
• In summary, subtext is the underlying message that is communicated through nonverbal cues, tone, context, or other indirect means, and can reveal the speaker's true intentions or emotions.

Additional Information

• Lower text refers to the smaller or secondary text that appears below or alongside the main text.
• Critical text refers to an analysis or evaluation of a text that highlights its strengths, weaknesses, and underlying meanings.
• Appended text refers to additional text that is added to the end of a document, often as an addendum or supplementary material.

Both Statement I and Statement II are false. 

Key PointsStatement - I: In the transmission model of communication, the emphasis is not on the process of communicating.

• The transmission model of communication emphasizes the process of transmitting information from a sender to a receiver.
• It assumes that communication is a linear process in which a message is sent by the sender, travels through a channel, and is received by the receiver.

However, statement I is false, as the transmission model does focus on the process of communicating.

Statement - II: On the other hand, the symbolic model does not focus on the process of exchange of information

• The symbolic model of communication emphasizes the process of creating and interpreting symbols used in communication, such as language, images, and gestures.
• It emphasizes that meaning is created through a shared understanding of these symbols and their use.

However, statement II is also false, as the symbolic model does focus on the process of exchange of information.

Communication codes are used to analyze and interpret messages conveyed through various forms of communication, and provide a framework for understanding the underlying meanings and intentions behind them.

Key Points 

Hence the correct match is A - III, B - IV, C - I, D - II

Calculation:

The profitability per outlet for each showroom in 2020:

For Showroom A:

Profitability per outlet = (Total profit of Showroom A in

2020)/(Number of outlets ×  Average sales per outlet in 2020)

= (80 lakh)/(2 × 100 lakhs = 0.4

For Showroom B:

Profitability per outlet = (Total profit of Showroom B in

2020)/(Number of outlets ×  Average sales per outlet in 2020)

= (250 lakh)/(4 × 340 lakh) ≈ 0.1838

For Showroom C:

Profitability per outlet = (Total profit of Showroom C in 2020)/

(Number of outlets × Average sales per outlet in 2020) = (80

lakh)/(1 × 120 lakh) ≈ 0.6667

For Showroom D:

Profitability per outlet = (Total profit of Showroom D in 2020) /

(Number of outlets × Average sales per outlet in 2020) = (240

lakh)/(5 ×180 lakh) ≈ 0.2667

For Showroom E:

Profitability per outlet = (Total profit of Showroom E in 2020) /

(Number of outlets × Average sales per outlet in 2020) = (300

lakh)/(3 × 360 lakh) ≈ 0.277

For Showroom F:

Profitability per outlet = (Total profit of Showroom F in 2020) /

(Number of outlets × Average sales per outlet in 2020) = (30

lakh)/(5 × 80 lakh) ≈ 0.075

Based on the calculated values, the highest profitability per outlet in 2020 was for Showroom C, which had a profitability per outlet of approximately 0.6667.

Therefore, the correct answer is C.

Concept used: 

Percentage increase = \(\dfrac{difference}{2020's AverageProfit} \times 100\)

Average = Sum of observation / Number of observations

Calculation:

Average Profit per outlet of A in 2020 = 80 ÷ 2 = 40

Average Profit per outlet of A in 2021 = 120 ÷ 3 = 40

Profit% increase in A = \(\dfrac{40-40}{40} \times 100\) = 0%

Similarly,

Profit% increase in B = \(\dfrac{{400\over6} - {250\over4}}{250\over4} \times 100\) = 6.67%

Profit% increase in C = \(\dfrac{{100\over3} - 80}{80} \times 100\) = - 58.34% (Loss)

Profit% increase in D = \(\dfrac{{360\over6} - {240\over5}}{240\over5} \times 100\) = 25%

Profit% increase in E = \(\dfrac{{320\over4}-{300\over3}}{300\over3} \times 100\) = - 20% (Loss)

Profit% increase in F = 0%

∴ HP-Showroom D experienced the highest percentage increase in average profit per outlet in 2021 over that in 2020.

Given:

Total Profit = 30 Lakhs

Total Sales = 80 × 5 = 400 lakhs

Concept used:  

Investment = Sales - Profit

Calculation:

⇒ Total Investment = 400 - 30 = 370 lakhs

∴ The total investment of HP-showroom F in the year 2020 was Rs. 370 lakhs.

Concept used: 

Total Sales = Number of outlets × Sales per outlet

Calculation: 

Total sales of A = 2 × 100 = 200

Total sales of B = 4 × 340 = 1360

Total sales of C = 1 × 120 = 120

Total sales of D = 5 × 180 = 900

Total sales of E = 3 × 360 = 1080

Total sales of F = 5 × 80 = 400

∴ Total sales from all the outlets of a showroom was the highest in the year 2020 for the HP-showroom B.

Concept used: 

Percentage increase = \(\dfrac{difference}{2020's Data} × 100\)

Calculation:

Profit% increase in D = \(\dfrac{120}{240} × 100\) = 50%

Total sales in 2020 = 180 × 5 = 900 lakhs

Total SAles in 2021 = 240 × 6 = 1440 lakhs

Sales% increase in D = \(\dfrac{540}{900} × 100\) = 60%

⇒ Required Ratio = 60 : 50 = 6 : 5

∴ The ratio of the percentage increase in sales to the percentage increase in profit for the HP-Showroom D in all the outlets in 2021 over 2020, was 6 : 5.

Both Statement I and Statement II are true.

Key PointsStatement I: Course material provided through digital platforms like SWAYAM helps learners go through it at any time and at any place.

Explanation: Digital platforms like SWAYAM provide learners with access to course materials anytime and anywhere, allowing them to learn at their own pace and convenience.

• Learners can access digital resources such as e-books, videos, and quizzes from their mobile devices, laptops, or desktops, making learning more flexible and accessible.

Thus Statement I is true. 

Statement II: Discussion boards work as asynchronous mediums as anyone can post any question or reply at any time.

Explanation: Discussion boards are an asynchronous form of communication where participants can post questions, comments, or replies at any time, without needing to be online simultaneously.

• This allows learners to engage in discussions at their convenience, and also enables a wider range of participation from learners who may be in different time zones or have different schedules.
• Discussion boards can facilitate meaningful interactions between learners and instructors, and also promote collaborative learning by encouraging peer-to-peer discussions and knowledge sharing.

Thus Statement II is also true.

Lecture method of teaching involves delivering content in a spoken form to a group of learners.

Key Points

• The lecture method of teaching involves the teacher delivering a content-rich presentation to students in a clear and concise manner.
• The primary aim of the lecture method is to impart knowledge to the students through a teacher-centered approach, where the teacher is the primary source of information.
• The lecture is often supported by visual aids such as PowerPoint presentations, handouts, and diagrams to facilitate learning.
• The content is delivered in a lucid language to ensure that it is easy for the students to comprehend and understand the subject matter.
• The lecture method is widely used in higher education settings, but it can also be applied in lower education levels with modifications.

Additional Information

• Small step presentation with feedback provided: This describes the incremental or mastery learning approach.
• Production of large number of ideas: This describes brainstorming or divergent thinking techniques.
• Theme based interaction among participants: This describes a discussion or group activity approach.

The preface to a book is an example of feedforward communication because it provides the reader with information about what to expect in the upcoming text.

Key Points

• Preface serves as a form of communication that prepares the reader for what is to come, giving them a sense of direction and purpose before they begin reading.
• In the preface, the author may explain the purpose of the book, provide background information on the topic, and outline the structure or organization of the content.
• By doing so, the author is engaging in feedforward communication, which is a type of communication that focuses on providing information that helps the receiver to better understand and prepare for future interactions.
• In essence, the preface acts as a guide or roadmap for the reader, helping them to navigate the content of the book and better comprehend the ideas and concepts presented.
• It is an important form of communication that sets the tone for the rest of the book and helps to create a positive reading experience for the reader.

 Additional Information

 

• Convoluted communication refers to complex and difficult-to-understand messages.
• Ritualistic communication refers to repetitive and formulaic messages that follow a set pattern or format.
• Informal communication refers to casual and spontaneous messages that are exchanged in a relaxed and unstructured manner.

The logical fallacy exemplified in the given statement is Ad Hominem.

Key Points

• "No one can criticize the Freudian psychoanalysis unless the one who criticizes himself has been psychoanalysed". This is Ad Hominem because the statement attacks the character or personal qualities of the person making the criticism rather than addressing the validity of the criticism itself.
• By suggesting that only those who have been psychoanalyzed can criticize Freudian psychoanalysis, the speaker is implying that anyone who has not undergone psychoanalysis is not qualified to make an informed criticism.
• This is a flawed argument because it ignores the substance of the criticism and instead attacks the credibility of the critic.
• Ad hominem arguments are considered fallacious because they are not logically valid and do not address the issue at hand.

Additional Information

• Appeal to authority: Using the opinion or position of an authority figure to support an argument.
• Appeal to Ignorance: Arguing that a proposition is true because it has not been proven false, or vice versa.
• Equivocation: Using a term in different senses in an argument, leading to a misleading conclusion.

Key Points

• The proposition "All frogs are amphibians" can also be expressed in the form of "No frogs are non-amphibians" which is logically equivalent to the given proposition.
• This is because if all frogs are amphibians, then it is also true that no frogs can be anything other than amphibians.
• In other words, if something is not an amphibian, then it cannot be a frog.
• Therefore, the statement "No frogs are non-amphibians" is logically equivalent to "All frogs are amphibians".
• The given problem involves the square of opposition, which is a diagram representing the relationships between categorical propositions with the same subject and predicate.
• Specifically, it involves the conversion of the proposition
• "All frogs are amphibians" to its logically equivalent proposition, which is "No frogs are non-amphibians."
• This is an example of the conversion of an A proposition to an E proposition in the square of opposition.

In syllogism, a proposition is a statement that asserts or denies something about a subject, and it is used to form a logical argument.

Key Points

• The given proposition "some fishes are not amphibians" is false, which means that all fishes are amphibians.
• This is because if there is at least one fish that is not an amphibian, then the proposition "some fishes are not amphibians" would be true.
• Based on this, we can infer that the proposition "All fishes are amphibians" (option B) is true, since it is the opposite of the original false proposition.
• We can also infer that the proposition "Some fishes are amphibians" (option D) is true, since we have established that all fishes are amphibians, so there must be at least some fishes that are amphibians.

Therefore, options B and D are the correct answers.

The Correct answer is: A and D only (Option 4)

Key Points

• Statement A: "All frogs are amphibians"
• This is a Universal Affirmative (A-type) proposition of the form "All A are B".
• It states that the entire class of frogs is included in the class of amphibians.
• Statement D: "No frogs are amphibians"
• This is a Universal Negative (E-type) proposition of the form "No A are B".
• It states that the class of frogs is completely excluded from the class of amphibians.
• Relation between A and D
• A (Universal Affirmative) and E (Universal Negative) are Contraries.
• Contraries cannot both be true (it is impossible for all frogs to be amphibians and at the same time no frog to be an amphibian).
• But they can both be false (for example, if some frogs are amphibians and some are not, then both "All" and "None" are false).
• Why not B and C?
• Statement B ("Some frogs are amphibians" – I-type) and Statement C ("Some frogs are not amphibians" – O-type) are Subcontraries.
• Subcontraries can both be true (if some frogs are amphibians and some are not), but they cannot both be false.

Additional Information

• Square of Opposition:
• A-type (Universal Affirmative): All A are B.
• E-type (Universal Negative): No A are B.
• I-type (Particular Affirmative): Some A are B.
• O-type (Particular Negative): Some A are not B.
• Relations:
• Contradictory: A ↔ O, E ↔ I (cannot both be true, cannot both be false).
• Contrary: A ↔ E (cannot both be true, but can both be false).
• Subcontrary: I ↔ O (can both be true, but cannot both be false).
• Subalternation: A → I and E → O (truth flows downward, falsity upward).

The argument "Sound is eternal because it is audible" is an example of the fallacy of a sadharana (narrow middle term) according to Nyaya, a classical Indian school of Logic.

 Key Points

• This is because the argument is based on an equivocation or ambiguity in the middle term "audible."
• The term "audible" is being used in two different senses - in one sense, it means "that which can be heard," while in the other sense, it means "that which exists."
• The argument therefore assumes that sound is eternal simply because it can be heard, which is a non-sequitur and does not logically follow.
• The fallacy of a narrow middle term occurs when the middle term of an argument is too narrow, vague or ambiguous, leading to a faulty conclusion.

Key PointsA megabyte (MB) is a unit of digital information that represents approximately one million bytes, while a terabyte (TB) is a unit of digital information that represents approximately one trillion bytes.

2048 Terabytes = 2048 x 2⁴⁰ bytes

2048 x 2⁴⁰ bytes = 2048 x 2⁴⁰ x 8 bits (since there are 8 bits in a byte)

2048 x 2⁴³ bits = 2¹¹ x 2⁴³ bits

2¹¹ x 2⁴³ bits = 2⁵⁴ bits

Therefore, 2048 Terabytes is equal to 2⁵⁴ bits of data storage.

Key PointsWeb 2.0 is a term used to describe the second generation of the World Wide Web.

• It is characterized by a shift from static web pages to dynamic, interactive web applications that allow users to contribute, share and collaborate online.
• Social media and user-generated web content are some of the key features of Web 2.0, as they enable users to create and share content, connect with others and participate in online communities.
• Web 2.0 platforms such as Facebook, Twitter, YouTube, and Wikipedia have transformed the way we communicate, access information and collaborate online, giving rise to a new era of social networking, knowledge sharing, and collective intelligence.

Additional Information

• Hypertext Markup Language (HTML) is a programming language used to create web pages.
• A static website is a website that displays the same content to all users.
• Intelligent website uses algorithms to personalize content and respond to user behavior.

Statement I is false but Statement II is true.

Key PointsStatement - I: Video cards and sound cards are typical examples of computer software.

• Video cards and sound cards are not examples of computer software.
• They are hardware components that are installed in a computer to provide specific functionality, such as improved video or audio performance.

Thus Statement I is incorrect.

Statement - II: Examples of software utilities include anti-virus software, anti-spyware software and screen savers.

• Software utilities are programs designed to perform specific tasks, such as maintaining the security of a computer, optimizing its performance, or customizing its appearance.
• Examples of software utilities include anti-virus software, anti-spyware software, and screen savers.

Thus, Statement II is true.

Key PointsA. Hypertext links in the WWW are designed to be unidirectional, which means that the destination of a link may be moved or deleted without the source being notified, resulting in broken links.

• This statement is true.
• Hypertext links in the World Wide Web (WWW) are unidirectional, meaning they only point to a destination URL. If the destination of a link is moved or deleted, the source URL will not be notified, and the link will become broken.

B. The Google search engine algorithm is secret, so the general public does not know how the results of a search are being ranked when presented to a user.

• This statement is true. The Google search engine algorithm is a closely guarded secret, and the general public does not know exactly how the search results are being ranked when presented to a user.
• However, Google has provided some general information about how the algorithm works over the years.

C. Web search engines collect personal data and use that data to target users with customized advertising.

• This statement is true. Many web search engines, including Google, collect personal data from users such as search history and location data, and use this data to target users with customized advertising.
• This is one of the ways that web search engines make money.

Key Points 

The correct match is A - III, B - I, C - IV, D - II

Non-point sources of water pollution are those that are diffuse and do not originate from a specific location or point source.

 Key Points

• Non-point sources of water pollution are typically caused by activities such as agricultural runoff, stormwater runoff, and atmospheric deposition.
• Episodic sources refer to those that occur irregularly or intermittently, such as spills or accidents.
• These can also contribute to non-point source pollution.
• Non-point sources of pollution can be difficult to monitor and control because they come from a variety of sources and are spread out over a large area, making it challenging to identify and address the specific sources of contamination.

Therefore, the correct options are B, C, and E.

Biofuels are fuels that are derived from renewable biological sources such as crops, plant matter, and animal waste.

 Key Points

• Biofuels are considered to be a cleaner alternative to fossil fuels because they produce fewer greenhouse gases when burned.
• Gasoline and methane are not biofuels as they are derived from non-renewable sources such as crude oil and natural gas, respectively.
• Methanol and ethanol are considered to be biofuels as they can be produced from renewable sources such as sugarcane, corn, and switchgrass.
• Methanol is produced from the gasification of biomass or the distillation of wood, while ethanol is typically produced by fermenting crops such as corn or sugarcane.

Therefore, the correct options are B and D.

Statement I is true but Statement II is false.

Key PointsStatement - I: International Solar Alliance's present post of President is held by India.

• The International Solar Alliance (ISA) is an intergovernmental organization that aims to promote solar energy globally.
• The International Solar Alliance (ISA) is a treaty-based intergovernmental organization headquartered in India.
• The present post of President of ISA is indeed held by India.

Thus, Statement I is true.

Statement - II: The United States of America is not a member of International Solar Alliance.

• The United States of America is a member of the International Solar Alliance.
• ISA was launched in 2015 at the United Nations Climate Change Conference (COP21) in Paris.
• The country became a member in 2018, and its membership was seen as a significant step towards strengthening the organization's efforts to promote solar energy globally.

Therefore, statement II is false.

Key Points 

Hence A - III, B - I, C - IV, D - II is the correct option.

Statement I is false but Statement II is true.

Key PointsStatement - I: United Nations Framework Convention on Climate Change (UNFCC) was framed during Kyoto Protocol. 1997.

• The United Nations Framework Convention on Climate Change (UNFCCC) was adopted in 1992, not during the Kyoto Protocol in 1997.
• The UNFCCC is an international treaty that aims to prevent dangerous human interference with the climate system by stabilizing greenhouse gas concentrations in the atmosphere.

Conclusion: Statement I is false, as the UNFCCC was adopted before the Kyoto Protocol.

Statement - II: Kyoto Protocol set up different limits of carbon emissions for individual nations, depending on their output before 1990.

The correct answer is Statement I is correct but Statement II is incorrect. 

Key Points

• Refer to the lines: 
• The British agent, Captain, Wade, told the Maharaja that the expansion of trade in his (the Maharaja's) dominions would result only after singing the treaty. But the British agencies had disrupted the economy of the Sikh state by imposing a heavy toll of Rs. 570 on the boats carrying large loads.
• This included the pashmina shawl output from 20,000 looms that were operating in Kashmir. The shawls were exported mainly to the European market, especially France, where they posed stiff competition to woollen manufacturers from Britain.
• The passage states that Pashmina shawls from Kashmir were exported mainly to the European market, especially France, where they posed stiff competition to woollen manufacturers from Britain.
• However, it also mentions that the British had imposed a heavy toll on the boats carrying large loads, including Pashmina shawls, which disrupted the economy of the Sikh state.
• Therefore, Statement - I is correct as Pashmina shawls were quite popular in Europe, but Statement - II is incorrect as the British did not make it easy for Kashmiri manufacturers to export the Pashmina shawls to Europe.

The correct answer is Both A and R are true but R is not the correct explanation of A.

Key Points

• Refer to the lines:
• Under the treaty, signed reluctantly by the Sindh amirs, the British obtained the right to take the final decision regarding taxation duties on goods passing through the Indus to the Arabian Sea. This was a variation of a gun-boat diplomacy with which the advancing British seized the veto in their hands to control the entire trade flow from Central Asia to Sindh and thereby the right to manipulate the economies of the regions and the states, including that of Ranjit Singh whose removal was not on their agenda.
• The next step was to coerce Ranjit Singh to sign the treaty, opening Sutlej to commerce as well.
• The passage states that the British coerced Ranjit Singh to sign the treaty, which opened up the Sutlej River to commerce. It also mentions that the British had alr but eady signed a one-sided treaty with two Sindh amirs to throw open the Indus to their military and political penetration.
• Therefore, Assertion A is true as the British did want Ranjit Singh to sign the treaty.
• ​According to the passager, "The British wanted to control the trade flow from Central Asia to Sindh and manipulate the economies of the regions and states, including that of Ranjit Singh whose removal was not on their agenda. By controlling the trade through the Indus, the British would have a significant say in the region's economic affairs.
• This is being said for different reason as it has been explained in the passage that Ranjit Sigh's removal was not on their agenda.
• Therefore, Reason R is true, but it is not the correct explanation for Assertion A.

The correct answer is A and B only.

Key Points

• Refer to the lines: Aware of the high stakes involved in seizing control over the Indus for navigation, the British persuaded two Sindh amirs, Rustam Khan, the Amir of Khanpur and Murad Ali of Hyderabad, to enter into a one-sided treaty and as proxies to throw the Indus open to the British Military and political penetration.
• The passage mentions that the British persuaded two Sindh amirs, Rustam Khan, the Amir of Khanpur, and Murad Ali of Hyderabad, to enter into a one-sided treaty with them to throw the Indus open to British military and political penetration.
• However, there is no mention of the British persuading Ranjit Singh to enter into a treaty with them in this particular context.
• Therefore, option 1) A and B only is the correct answer.

The correct answer is Statement I is incorrect but Statement II is correct.

Key Points

• The passage does not suggest that the Sindh amirs were pleased and willing to sign the treaty with the British. In fact, it mentions that the treaty was one-sided, and the Sindh amirs signed it reluctantly.
• The passage states that the British persuaded Rustam Khan, the Amir of Khanpur, and Murad Ali of Hyderabad, to enter into a treaty with them to throw the Indus open to British military and political penetration. The Sindh amirs signed the treaty under pressure from the British, who used gun-boat diplomacy to gain a veto over the taxation duties on goods passing through the Indus to the Arabian Sea.
• Therefore, Statement I is incorrect.
• The passage does suggest that controlling the navigation through the Indus was high on the British agenda. The British wanted to control the trade flow from Central Asia to Sindh and gain a significant say in the economic affairs of the region. By controlling the navigation through the Indus, the British could manipulate the economies of the regions and states.
• Therefore, Statement II is correct.

Hence, the correct answer is option 4) Statement I is incorrect but Statement II is correct.

The correct answer is Both A and R are true and R is the correct explanation of A.

Key Points

• The passage states that the British persuaded two Sindh amirs to enter into a one-sided treaty with them to throw the Indus open to British military and political penetration. The British obtained the right to take the final decision regarding taxation duties on goods passing through the Indus to the Arabian Sea.
• This allowed the British to control the trade flow from Central Asia to Sindh and manipulate the economies of the regions and states. Similarly, the British coerced Ranjit Singh to sign a treaty, opening up the Sutlej River to commerce.
• Therefore, Assertion A is true as the British wanted to control the navigation routes through the rivers.
• The reason for this is mentioned in Reason R. Rivers were used for trading goods, and the British found it lucrative to make a profit by controlling the trade. By controlling the trade, the British could manipulate the economies of the regions and states, and gain a significant say in the economic affairs of the region.
• Therefore, Reason R is also true, and it is the correct explanation for Assertion A.
• Hence, option 1 is the correct answer.
