UGC NET Questions (Paper – 1)

ABC is conceived as a national-level digital credit repository. Students earn credits from recognised HEIs, and these are recorded in their ABC account. When they move institutions or re-enter after a break, credits can be transferred and counted towards a qualification. This enables genuine portability and lifelong learning.

Option A:
Storing money is the role of financial institutions, not ABC.

Option B:
This option correctly describes ABC as a credit, not financial, bank.

Option C:
Question-setting for exams is handled by universities and testing agencies, not ABC.

Option D:
Accreditation is done by NAC and related regulators, not by the credit bank.

Encryption uses mathematical algorithms to transform plaintext into ciphertext that appears meaningless without the correct key. This protects the confidentiality of sensitive data as it travels over networks or resides on storage devices. Even if attackers intercept the data, they cannot easily interpret it without decryption keys. Thus, the protective process described in the stem is encryption.

Option A:
Option A, compression, reduces the size of data for efficient storage or transmission but does not intentionally hide the content from unauthorised viewers.

Option B:
Option B is correct because encryption is explicitly defined as encoding information to prevent unauthorised disclosure and is a cornerstone of contemporary ICT security practices.

Option C:
Option C, formatting, prepares storage media or arranges document appearance and does not inherently provide confidentiality.

Option D:
Option D, duplication, involves making copies of data, which can actually increase exposure rather than protect against access.

Non-point sources are diffuse and hard to trace to a single discharge point. Agricultural runoff occurs when rain washes fertilisers, pesticides and soil from many fields into streams and rivers. The pollution comes from a wide area, not one identifiable pipe. Therefore, diffuse farm runoff is a classic example of non-point source water pollution.

Option A:
Option A is incorrect because a factory discharge pipe has a clearly identified location. Such a pipe is a point source that can be monitored and regulated directly.

Option B:
Option B is incorrect; leakage from a specific underground tank has a discrete location and is therefore treated as a point source, even though detecting the leak may be challenging.

Option C:
Option C is correct as it describes pollution entering water bodies over large surfaces. Managing it requires land-use practices and watershed approaches rather than simple end-of-pipe treatment.

Option D:
Option D is incorrect because a sewage outlet from a treatment plant is another example of a point source. Its flow can be sampled and controlled at one point.

The memory level of teaching is the lowest level in the hierarchy of levels of teaching. It focuses on rote learning, drill and repetition to ensure that students can recall facts, definitions and formulas. At this level, learners are not expected to understand underlying meanings or relationships. Therefore, teaching that emphasizes memorization and recall of facts is correctly described as operating at the memory level.

Option A:
The reflective level of teaching involves complex problem-solving, hypothesis formation and critical thinking. At this level, students are encouraged to reflect on their thinking and evaluate evidence. Such processes go far beyond simple memorization, so this option does not match the description given in the stem.

Option B:
The understanding level of teaching aims at ensuring that students comprehend ideas, can interpret them and may apply them in familiar situations. It emphasizes meaning and relationships rather than simple recall. Consequently, it cannot be associated with teaching that is confined mainly to rote learning and drill.

Option C:
The autonomous level of teaching, when discussed, refers to learners taking responsibility for their own learning and being self-directed. It presupposes higher mental functioning and self-regulation, which are not features of rote learning. Therefore, this option does not align with the focus on memorization and drill.

Option D:
Memory level of teaching specifically denotes instruction that seeks to imprint information in memory through repetition, practice and recall-based questioning. It is teacher-centred, stimulus–response oriented and limited to lower-order objectives. Hence, this option accurately characterizes the kind of teaching described in the question.

The Green Credit Programme is intended to encourage positive environmental actions by various actors through a system of credits. Stakeholders who undertake approved activities, like plantation on identified degraded lands, receive green credits that can later be traded on a designated platform. The rules were notified under the Environment (Protection) Act in October 2023, and subsequent guidance has stressed voluntary participation and market incentives. This design aims to link ecological restoration with economic signals rather than relying only on command-and-control regulation. (moefcc-gcp.in)

Option A:
This option is incorrect because the programme is not limited to penalties; instead, it revolves around positive incentives in the form of tradable credits. While regulation remains important in environmental law, GCP specifically experiments with a market-based approach.

Option B:
Restricting participation to multinational corporations would undermine the programme’s emphasis on diverse stakeholders, including individuals, communities and domestic firms. Official documents explicitly mention a wide range of eligible actors.

Option C:
This option captures the core elements of the GCP: voluntary environmental actions, issuance of credits and tradability. It also highlights tree plantation on degraded land, which is one of the key activities envisaged. Because it aligns with official descriptions of the scheme’s intent and design, it is the correct answer.

Option D:
Financing only thermal power plants is not the focus of GCP; while decarbonisation of power is important, the programme is broader and not confined to a single sector. This statement therefore mischaracterises its scope.

Statements A, B and D are correct because they present both benefits and concerns related to large dams along with the need for due process. A notes potential advantages like irrigation and flood control, B recognises social and environmental costs such as displacement and submergence and D stresses the role of EIA and public hearings. Statement C is incorrect as dams alter river flows, sediment transport and aquatic habitats, affecting ecosystems and fisheries. Hence the correct combination is A, B and D only.

Option A:
Option A is incorrect because, although A and B are correct, it ignores D. Without acknowledging EIA and public hearings, the option fails to present the governance dimension of dam decisions, making it incomplete.

Option B:
Option B is correct as it combines all the true statements about the multifaceted impacts of large dams. It acknowledges benefits, costs and procedural safeguards while properly excluding C, which wrongly claims an absence of ecological impacts. This balanced view aligns with the unit’s treatment of the topic.

Option C:
Option C is incorrect because it includes B, C and D and accepts C as correct. Statement C denies ecological impacts that are widely documented in environmental studies, so its inclusion invalidates the combination despite the presence of B and D.

Option D:
Option D is incorrect as it groups A, C and D and leaves out B. It again accepts C, the incorrect statement, and neglects the important issue of displacement and land submergence discussed in B. Therefore, it cannot be chosen.

Upadhi is introduced to explain why an apparently universal relation between hetu and sadhya fails in some cases by revealing an unnoticed limiting condition. For example, the connection between smoke and fire holds only when certain conditions about fuel and ignition are met. Recognising the upadhi refines the vyapti so that it becomes genuinely exceptionless. Thus the restricting factor described in the stem is called upadhi.

Option A:
Option A is correct because upadhi literally means "subsidiary condition" and functions as a qualifier that saves genuine universals from overgeneralisation. It shows that the true vyapti is conditional upon the presence of this factor.

Option B:
Option B, udaharana, is the statement of rule with example and does not itself serve as a hidden constraint on the relation.

Option C:
Option C, paksha dharma, refers simply to a property present in the paksha and is not the special condition that limits the domain of a universal connection.

Option D:
Option D, samsaya, denotes doubt as a mental state and plays a role in prompting inquiry, not in technically restricting the scope of vyapti.

A Metropolitan Area Network spans a geographic region larger than a single building but smaller than a country, such as a city or a university campus. It often acts as a backbone that interconnects several local area networks. MANs can be implemented using high capacity fibre links and are sometimes managed by telecom providers. Therefore, the network described in the stem is a MAN.

Option A:
Option A is correct because MANs are defined in networking literature as covering metropolitan scale areas and linking multiple LANs, which matches the scope mentioned.

Option B:
Option B, LAN, is limited to smaller areas like offices or buildings and does not typically connect widely separated sites across a city.

Option C:
Option C, WAN, covers much larger geographic areas, often internationally, and would go beyond the scale indicated in the question.

Option D:
Option D, PAN, refers to very short range personal networks around an individual and is much smaller in scope than a MAN.

Statements A, B, C and E accurately identify sources of measurement error and strategies to reduce it. Poor wording and careless responding can both distort data, while standardised procedures and training investigators help make measurements more consistent. Statement D is false because measurement error directly undermines reliability by introducing random or systematic noise into scores. Therefore, the correct combination includes A, B, C and E but not D.

Option A:
Option A is correct because it includes the four statements that together show how errors arise and how they can be mitigated through design and training. It recognises that reliability depends on minimising such errors.

Option B:
Option B is incomplete as it excludes E, thereby neglecting the role of training in reducing interviewer or observer-related errors. Without E, the focus is limited to wording, respondent behaviour and standardisation but not human skill development.

Option C:
Option C is incorrect because it incorporates D, the claim that measurement error does not affect reliability. This directly contradicts the concept of reliability, which is weakened when error variance is high.

Option D:
Option D is wrong because it retains D and omits B, failing to highlight the impact of respondent carelessness on measurement quality while accepting a false statement about reliability. This leads to an inaccurate understanding of error sources and consequences.

Statements A, B, C and E are correct, while D and F are false. Causal reasoning does seek contributing factors, post hoc identifies a common fallacy based on mere sequence, and controlled comparison helps isolate causal variables. Exam questions often ask which explanation best accounts for observed facts, which is captured in E. D is wrong because temporal order alone does not prove causation, and F is wrong because correlation does not automatically establish a causal link. Thus A, B, C and E only is the correct combination.

Option A:
Option A is incomplete because it omits E, overlooking the way UGC NET uses cause and effect items to test evaluative skills. Although A, B and C are conceptually sound, they do not reflect this exam context. Hence A, B and C only cannot be chosen.

Option B:
Option B is incorrect because it drops A, failing to state what causal reasoning tries to do in general. Having only B, C and E leaves out the overall idea of causation itself. This omission makes the option conceptually weaker than the full set of correct statements.

Option C:
Option C is correct since it unites the description of causal inquiry, a classic fallacy, a methodological tool and the exam style of questioning. By excluding D and F, it also protects against common confusions between sequence, correlation and causation. Therefore this option fits both theory and practice.

Option D:
Option D is wrong because it includes D, which absurdly claims that temporal succession always suffices for causation, and omits C’s point about controlled comparison. Accepting D leads to many false causal attributions. So A, B, D and E only is not a valid answer.

A pilot study is a trial run of the main research project conducted on a smaller scale. It helps to identify practical problems in sampling, data collection tools and analysis procedures. Insights from the pilot are used to refine the design before the full study is launched. Therefore, a small preliminary feasibility study is correctly termed a pilot study.

Option A:
A case study is an in-depth analysis of a particular case such as an organisation or individual. It is not simply a small-scale test run of a larger research design. Hence, it does not match the function described in the question.

Option B:
A survey study is a full-scale investigation using questionnaires or interviews on a target population or sample. It is one substantive method rather than a preliminary test of procedures. So it is not the term used for a trial run.

Option C:
A pilot study specifically examines whether the planned methods, instruments and logistics work as expected. It can reveal ambiguities in questions, sampling difficulties and timing issues. Because of this feasibility-testing role, it fits the stem exactly.

Option D:
A longitudinal study follows the same participants over a long period to examine change, which is a full design rather than a short preliminary test. It does not primarily function as a feasibility assessment step. Therefore, it is not the correct option.

Laukika pratyaksha encompasses all ordinary perceptions generated by the standard interaction of the five senses with their corresponding objects. It includes both indeterminate and determinate stages so long as the source is usual sense contact. Nyaya contrasts this with extraordinary forms of perception that go beyond standard sensory operations. Therefore the empirical perception in the stem is called laukika pratyaksha.

Option A:
Option A, alaukika, denotes extraordinary perception that occurs in atypical ways, such as perception of universals or yogic insight, and does not describe ordinary sensory experience.

Option B:
Option B, nirvikalpa, refers to indeterminacy of content and can apply to both ordinary and extraordinary perceptions, so it is not tied to the empirical nature of the source in the way the stem suggests.

Option C:
Option C is correct because laukika literally means "worldly" and captures the normal, commonsense realm of perception that most knowledge about the external world relies upon.

Option D:
Option D, yogaja, is a specific kind of alaukika perception arising from yogic discipline, not the general class of everyday sense-based awareness.

The fallacy of composition occurs when one concludes that because each part of a whole has some property, the whole itself must also have that property. This ignores how components may interact or combine in ways that change the overall characteristics. Logical scrutiny requires considering whether the property is preserved when parts are assembled. Thus the mistaken inference described in the stem is the fallacy of composition.

Option A:
Option A, division, is the complementary error of inferring that each part has a property simply because the whole does. It runs from whole to part rather than from part to whole and so does not fit the stem.

Option B:
Option B is correct because composition captures exactly the part-to-whole misreasoning. For example, from “each player on this team is excellent” it does not automatically follow that “the team is excellent”, since teamwork and strategy also matter.

Option C:
Option C, hasty generalisation, involves drawing a broad conclusion about a population from an insufficient or unrepresentative sample, which is a different type of inferential mistake.

Option D:
Option D, post hoc, concerns erroneous causal inference based on temporal succession, not on part–whole relationships.

D is wrong because the total probability of all simple events in a well-defined sample space must sum to exactly 1, not more than 1. Statements A, B, C and E are correct: probabilities are bounded between 0 and 1, probabilities 0 and 1 represent impossibility and certainty within the model, mutually exclusive events have additive probabilities, and NET questions often test both conceptual understanding and simple calculations. Since only D contradicts the axioms of probability, the correct answer is the option that lists D only as wrong.

Option A:
Option A is correct because it isolates D as the single statement that violates the basic rule that the total probability over a sample space equals 1. It implicitly accepts that the other statements are consistent with elementary probability theory and exam practice.

Option B:
Option B is incorrect as it also treats A as wrong, even though A correctly states the allowed numerical range of probability values. By labelling A incorrect, this option misrepresents one of the most fundamental facts about probability.

Option C:
Option C is wrong because it groups C with D as wrong, despite C correctly stating the addition rule for mutually exclusive events. Including a true rule alongside a false statement makes this option invalid.

Option D:
Option D is also incorrect since it adds B and C to the set of wrong statements, even though both B and C are standard properties of probability. This option rejects several correct ideas along with the one incorrect statement.

Adaptation consists of adjustments that reduce damage or increase resilience to the impacts of climate change. Building infrastructure designed to withstand coastal flooding and storm surges, together with effective early warning systems, helps communities live with sea-level rise and more intense storms.

Option A:
Option A is incorrect because switching from coal to solar primarily reduces emissions and is therefore a mitigation measure.

Option B:
Option B is incorrect; better fuel efficiency lowers greenhouse gas emissions from transport and is also mitigation.

Option C:
Option C is incorrect since a carbon tax is a policy instrument intended to reduce fossil fuel use and emissions, again falling under mitigation.

Option D:
Option D is correct as it focuses on coping with and reducing vulnerability to climate impacts, which is the essence of adaptation.
