UGC NET Questions (Paper – 1)

The decimal system uses ten symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. Because a positional system's base equals the number of distinct digit symbols, the base of decimal is 10. Therefore, the number of distinct digit symbols in decimal is 10.

Option A:
Option A, 9, would omit one symbol and cannot represent all decimal digits. Since we clearly use ten distinct symbols, this count is too small.

Option B:
Option B is correct because counting from 0 to 9 gives ten unique digits used in everyday arithmetic. This property defines decimal as a base-10 system.

Option C:
Option C, 8, would correspond to an octal system, not to decimal. Octal digits range from 0 to 7 only.

Option D:
Option D, 16, describes the hexadecimal system, which uses digits 0–9 and letters A–F, not the decimal system.

The pattern here is given by aₙ = 3n⁴ − n² + 4 with n starting from 1. Substituting n = 1, 2, 3, 4 and 5 yields 6, 48, 238, 756 and 1854, which are exactly the numbers in the series. Applying the same expression for n = 6 gives 3856. Hence 3856 is the only value that keeps this quartic-based pattern consistent.

Option A:
Option A, 3824, is 32 less than the value obtained from aₙ = 3n⁴ − n² + 4 when n = 6. To accept 3824 we would need to subtract 32 only at the last term, which is not indicated by the earlier entries. As a result, this option does not preserve the polynomial rule and is incorrect.

Option B:
Option B, 3840, is still smaller than the required value and does not equal the output of the formula at n = 6. It represents a partial correction toward the right term but still breaks the functional relationship. Therefore option B cannot correctly continue the series.

Option C:
Option C, 3856, matches exactly the value predicted by 3n⁴ − n² + 4 for n = 6. It respects the same combination of a fourth-power term and a negative square adjustment that shapes the growth of the sequence. Because the same rule explains all the given terms and leads naturally to 3856, this option is correct.

Option D:
Option D, 3872, is 16 greater than the polynomial value and cannot be generated by the rule for the sixth position. Introducing this extra amount would break the algebraic pattern that the series follows. Thus option D is not a valid continuation.

Statements A, B, C and D correctly relate “if”, “only if” and necessary conditions to their symbolic forms, and F is also true, while E is false. The biconditional is true exactly when p and q share the same truth value, not when they differ. Treating “only if” carefully is crucial for distinguishing what is necessary from what is sufficient. Hence the correct set of statements is A, B, C, D and F only.

Option A:
Option A is incomplete because it omits D and F, leaving out both the explicit link to necessary conditions and the exam relevance of misreading “only if”. Although A, B, C and E mention some relationships, they include E, which wrongly states the truth pattern of the biconditional. This makes the option incorrect.

Option B:
Option B is wrong because it includes E, which claims that “p if and only if q” is true when p and q differ in truth value. That is the truth condition for exclusive disjunction, not for the biconditional. Including E makes the combination logically inconsistent.

Option C:
Option C is correct as it gathers A, B, C and D, which correctly express equivalences and necessary condition symbolism, and F, which notes the importance of reading these connectives properly in exams. It excludes E, avoiding the confusion between biconditional and exclusive or. This matches standard logical teaching.

Option D:
Option D is incorrect since it omits A and replaces it with B, C, D, E and F. Without A, the equivalence of “p only if q” with “If p then q” is not stated, and including E still misrepresents the truth conditions of the biconditional. Therefore it cannot be the right answer.

Statements A, B and D are correct: indigenous knowledge contains sustainable practices, combining it with science can improve management and rights plus prior informed consent are key ethical principles. Statement C is incorrect because indigenous knowledge continues to be relevant for contemporary environmental problems like climate adaptation and biodiversity conservation. Therefore, the combination A, B and D only is correct.

Option A:
Option A is incomplete because it omits D, which rightly stresses the need for respecting rights and consent when using indigenous knowledge. Without D, ethical aspects are not fully represented.

Option B:
Option B is incorrect as it includes C, implying that indigenous knowledge is obsolete, which contradicts numerous examples of its contemporary value.

Option C:
Option C is incorrect since it groups B, C and D and treats C as correct. Although B and D are valid, the inclusion of C makes the combination unacceptable.

Option D:
Option D is correct because it includes all three true statements while excluding the disparaging and incorrect statement C. It reflects both the practical and ethical dimensions of using indigenous knowledge in environmental management.

NEP 2020 frequently refers to SEDGs as groups that face barriers due to social and economic conditions. These include SCs, STs, OBCs, minority communities, girls, differently-abled persons and others. Special schemes and funds are proposed to support them. The acronym explicitly stands for Socio-Economically Disadvantaged Groups.

Option A:
Option A mis-expands the acronym and does not relate to equity concerns.

Option B:
This option matches the text of NEP and clarifies the focus on disadvantaged learners.

Option C:
Option C invents a meaning that refers only to graduates, which is not the usage in the policy.

Option D:
Option D is unrelated to the equity framework described in NEP.

Statements A, C and D correctly capture the teacher’s socialising role. A is true because teachers introduce learners to shared norms and values through curriculum and interaction. C is true as teachers can model and promote respect for diversity, helping learners live in pluralistic societies. D is true since when teachers engage with the community, they help connect school experiences with wider social realities. B is false because effective value education requires dialogue, reflection and critical engagement, not mere reading of text, and E is false because learners observe teachers’ conduct closely and learn values from their behaviour; therefore A, C and D only is correct.

Option A:
Option A includes A, C and D, which together show transmission of values, promotion of cohesion and school–community connection. It excludes B and E, which minimise discussion and role modelling, and thus accurately represents the teacher’s socialising function. Hence this is the correct option.

Option B:
Option B lists A and C but omits D, ignoring the importance of community-related activities in strengthening the social role of the school. Without D, the description of the teacher as socialising agent is incomplete.

Option C:
Option C contains C and D only and leaves out A, which states the fundamental role of teachers in transmitting social values and norms. Because A is a core part of socialisation, this option cannot be considered complete or correct.

Option D:
Option D groups A, B, C and D but includes B, which restricts value education to reading text and ignores discussion and critical thinking. Including a false statement makes the combination logically inconsistent.

Option E combines A, C, D and E but accepts E, which wrongly claims that the teacher’s conduct is unimportant in value education. Since role modelling is central to value transmission, A, C, D and E only cannot be accepted as correct.

The IPCC AR6 Synthesis clearly states that the remaining carbon budget for 1.5°C is very small and shrinking quickly. It emphasises that rapid, deep and sustained emission cuts in the 2020s are essential to keep this temperature goal within reach. Early action reduces the chances of overshoot, lowers long-term costs and avoids locking in high-carbon infrastructure. Therefore, the option that highlights urgent and strong mitigation in this decade captures the heart of the report’s message.

Option A:
This option is correct because it directly reflects the wording used by the IPCC about rapid, deep and sustained cuts. It recognises that mitigation must happen now, not at some distant future date. It also links the scale and speed of emission reductions to the 1.5°C limit, which is central to the report.

Option B:
This option is incorrect because delaying major emission reductions until after 2050 would make 1.5°C practically unattainable. The report warns that postponement increases costs and risks of irreversible impacts. Therefore, it contradicts the urgency stressed in AR6.

Option C:
This option overemphasises lifestyle changes and ignores the need for structural shifts in energy, transport and land use. The report stresses that both demand-side and supply-side transformations are needed. Hence, it is incomplete and not the best answer.

Option D:
This option wrongly suggests that mitigation no longer matters. AR6 repeatedly states that every fraction of a degree of avoided warming reduces impacts and risks. So, claiming mitigation has no effect is directly opposed to the scientific findings.

Statements A, B, D and E accurately describe expectations regarding public disclosure. A is true because basic information on programmes, admissions and fees must be accessible. B is true as sharing decisions or summaries of statutory bodies promotes transparency. D is true since regulators and accreditation agencies often prescribe disclosure requirements. E is true because clear and student-friendly information helps applicants make informed choices. C is false because institutions are not discouraged from disclosure; rather, they are expected to be open, and F is false as outdated or inaccurate websites can damage credibility.

Option A:
Option A is incorrect because it omits E and thus fails to mention the importance of presenting information in a way that students can easily understand and use.

Option B:
Option B is incorrect because it includes only B, D and E and omits A, leaving out the fundamental requirement to provide basic programme and fee information online.

Option C:
Option C is incorrect because it ignores D and includes only A, B and E, not explicitly acknowledging that disclosure is often mandated by regulatory and accreditation norms.

Option D:
Option D is correct because it brings together A, B, D and E, the true statements that emphasise accessible information, transparency, regulatory norms and student-centred presentation, while excluding C and F, which wrongly discourage disclosure and dismiss the importance of website accuracy.

NEP 2020 uses the term SEDGs for groups facing social and economic barriers, such as SCs, STs, OBCs, minorities, girls, children in rural or remote areas and transgender persons. Economically privileged learners in elite urban schools are comparatively advantaged and hence least likely to be considered SEDGs.

Option A:
Scheduled Castes and Scheduled Tribes are explicitly recognised as socio-economically disadvantaged groups needing targeted support and therefore clearly fall within SEDGs.

Option B:
Children from rural and remote regions often face difficulties of access, infrastructure and quality, so they are typically included in SEDGs, not excluded.

Option C:
Economically well-off students in elite urban schools enjoy better resources and opportunities, so they are least likely to be categorised as SEDGs in NEP 2020.

Option D:
Transgender persons are specifically mentioned as needing special measures for inclusion and safety and therefore are part of the SEDG focus, not outside it.

Paralanguage includes vocal features such as pitch,volume and speed that accompany spoken words. Changing pitch and slowing speech draw attention to a key message without altering the words themselves. This is a classic use of paralanguage for emphasis.

Option A:
Semantics deals with meanings of words,not the way they are voiced.

Option B:
Proxemics involves physical distance between people,not voice quality.

Option C:
Therefore paralanguage accurately names the vocal behaviour described.

Option D:
Haptics concerns communication through touch,which is not referred to in the stem.

Rapid and unplanned urbanisation in developing countries often results in overcrowding, slum formation and stressed infrastructure. Basic services such as water supply, sanitation, transport and waste management become inadequate. Environmental problems like air pollution, water contamination and solid waste accumulation intensify. Hence, the most appropriate description is that it creates serious pressures which must be addressed through planned urban development, as stated in option D.

Option A:
Option A is incorrect because quality of life usually improves only when urban growth is planned and serviced. In many developing cities, rapid unplanned urbanisation actually worsens living conditions for large segments of the population, so it cannot be said that it always leads to higher quality of life.

Option B:
Option B is incorrect since concentrating people without adequate planning tends to magnify, not eliminate, environmental problems. Urban areas generate large amounts of waste and pollution, and insufficient management further intensifies these issues.

Option C:
Option C is incorrect because, although rural out-migration can create challenges, urbanisation is often associated with economic growth and structural transformation. The problem is not urbanisation itself but its unplanned and unmanaged nature.

Option D:
Option D is correct as it summarises the typical consequences of rapid, unplanned urbanisation: housing shortages, infrastructure stress and environmental degradation. It also highlights the need for planned interventions, which is a key point in people–environment discussions.

Modern online platforms enable users to respond through comments,shares and their own posts. This makes communication less one sided and more dialogic. The stem highlights these features,which define interactivity. Therefore interactive is the appropriate term.

Option A:
Hierarchical communication suggests rigid top down control,which does not capture participatory online spaces.

Option B:
Interactive communication allows two-way participation where users respond and co-create content,which matches commenting,sharing and creating posts.

Option C:
One way communication would not allow user responses and content creation.

Option D:
Purely mechanical would focus on devices rather than social exchange.

All four statements A, B, C and D correctly characterise multidisciplinary and multi-campus institutions. A is true because multidisciplinary universities deliberately span several domains of knowledge. B is correct as multi-campus institutions have multiple locations functioning under one overarching governance system. C reflects NEP 2020’s emphasis on large multidisciplinary universities and institutional clusters. D is also true since such structures can encourage resource sharing, interdisciplinary work and collaborative learning. As all statements are correct, the right option is A, B, C and D.

Option A:
Option A is incorrect because it selects only A and B and ignores C and D, thereby missing the policy thrust in NEP 2020 and the benefits of resource sharing and collaboration.

Option B:
Option B is incorrect because it includes A, B and C but omits D, which states the important advantages of such institutional arrangements for learning and resources. Without D, the portrayal is less complete.

Option C:
Option C is incorrect because it combines B, C and D and leaves out A. Excluding A removes the basic defining feature of multidisciplinary universities, which is the breadth of disciplines they cover.

Option D:
Option D is correct because it recognises that all four statements are accurate and complementary. It captures the conceptual, structural and policy dimensions of multidisciplinary and multi-campus institutions in a single combination.

Statement C is wrong because ethical clearance is closely related to feasibility; if approval cannot be obtained, the proposed study may not be permitted. Statements A, B, D and E are all correct: access, skills, money and time are central factors in deciding whether a project can realistically be carried out. Since C alone contradicts this understanding, the correct answer is the option that lists only C as wrong.

Option A:
Option A is incorrect because it includes A as wrong along with C, even though A correctly identifies access to participants or data as a key feasibility factor. Misclassifying A as wrong underestimates a practical precondition for research.

Option B:
Option B is correct because it isolates C as the only statement that fails to recognise the role of ethics in feasibility. It affirms that feasibility is a multi-dimensional judgement involving access, competence, resources and ethics.

Option C:
Option C is wrong because it adds D, claiming that financial resources are not an important feasibility factor, which is clearly false. Including D alongside C broadens the set of “wrong” statements beyond what the question requires.

Option D:
Option D incorrectly treats B and E as wrong together with C, even though B and E correctly describe the importance of skills and time. Thus it rejects more statements than actually conflict with good research planning.

Semantic barriers arise when different meanings are attached to the same word or phrase by sender and receiver. The term "research" is broader than laboratory experiments,but some students restrict its meaning. This mismatch in understanding is a semantic barrier. It is rooted in language and concepts.

Option A:
Physical barriers involve environmental obstacles such as noise or distance,not word meanings.

Option B:
Semantic barriers are caused by misunderstanding or limited meanings of words/concepts,which is exactly what happens with the term “research” here.

Option C:
Psychological barriers come from emotions like fear or low confidence,rather than vocabulary.

Option D:
Cultural barriers result from differing social norms and values,not from the specific misuse of an academic term in this example.
