UGC NET Questions (Paper – 1)

NEP 2020 envisions the secondary stage as four years of multidisciplinary and flexible learning. Students can choose combinations of subjects across arts, sciences and vocational areas according to their interests, gradually moving away from rigid streams.

Option A:
Maintaining strict, non-overlapping streams runs counter to NEP’s call for multidisciplinary options and broader exposure in secondary education.

Option B:
This option captures the idea of flexibility and mixing of disciplines, which is central to the new secondary curriculum.

Option C:
Replacing all academic subjects with only vocational training would narrow opportunities and is not suggested by the policy.

Option D:
NEP does not abolish examinations at the secondary level; it calls for better-designed, less rote-oriented and less high-stakes assessments instead.

The transactional model views communication as a dynamic process in which all participants act as senders and receivers simultaneously. Meaning is co created through ongoing interaction. The stem describes such mutual influence between teacher and students. Therefore it reflects the transactional model.

Option A:
Linear models assume one way transmission and do not capture simultaneous influence.

Option B:
Thus transactional is the best answer because it explicitly treats classroom meaning as co-created through simultaneous interaction.

Option C:
Hypodermic models portray messages as injections into passive audiences and ignore co creation.

Option D:
Two step models focus on opinion leaders and mass media,not classroom interaction.

Statements A, C and E are correct, whereas B, D and F are wrong and together form the correct set of wrong statements. Feedback indeed completes the communication loop, multiple channels can reinforce understanding, and student questions are a clear form of feedback. However, noise can be physical or psychological, communication does not end until meaning is constructed, and channel selection can influence how much noise distorts the message. Thus B, D and F misrepresent key aspects of the communication cycle.

Option A:
Option A is incorrect because it lists only B and D as wrong and omits F. While B and D are indeed wrong, F also claims that channel choice does not affect exposure to noise, which is false. Leaving F out results in an incomplete set of wrong statements.

Option B:
Option B is correct because it identifies B, D and F as the wrong statements and implicitly recognises that A, C and E are true. This matches communication theory on noise, feedback and channel effects. The option therefore accurately captures all and only the incorrect statements in the item.

Option C:
Option C is incorrect since it wrongly classifies A as wrong along with B, D and F. A correctly states the function of feedback in closing the loop, so including it in the wrong set contradicts basic communication models. Hence this combination cannot be accepted.

Option D:
Option D is incorrect because it also treats C as wrong, even though C correctly describes the use of multiple channels such as speech and board work. Labelling C as wrong undermines the understanding of multimodal classroom communication. Therefore this option is invalid.

Statements A, B and C correctly describe major data collection tools, and E adds the important idea of triangulation. Questionnaires, structured interviews and participant observation are standard methods in educational and social research. Statement D is false because no single tool is guaranteed to answer all research questions in every study. Using multiple methods, as in E, can help corroborate results and increase credibility. Therefore the correct combination includes A, B, C and E but excludes D.

Option A:
Option A is incorrect because it omits E, even though triangulation through multiple methods is a recognised strategy for enhancing the robustness of research findings. A correct option must include this important point along with the basic tool descriptions.

Option B:
Option B includes D, which wrongly suggests that a single tool always suffices, contradicting the idea of methodological flexibility and triangulation. Including such an absolute claim makes the option conceptually unsound.

Option C:
Option C lists B, C and E but leaves out A, thereby ignoring the role of questionnaires as a major tool in many research designs. Since A is clearly a correct statement, its omission renders the combination incomplete.

Option D:
Option D is correct because it groups the three accurate descriptions of individual tools with the accurate statement about using multiple methods. It properly excludes D, which unjustifiably elevates a single tool as universally sufficient, and thus contains all and only the correct statements.

Option E is incorrect because it includes D, the false assertion about a single tool being always sufficient, and simultaneously omits B, which is a true statement about structured interviews. This mixture of omission and error invalidates the option.

NEP 2020 conceives MERUs as exemplary universities that combine strong teaching with cutting-edge research across disciplines. They are meant to serve as benchmarks and role models for other institutions, helping raise the overall quality of higher education.

Option A:
Small local tuition centres for primary school children do not match the description of large, high-quality multidisciplinary universities given in the policy.

Option B:
This option is correct because it captures MERUs as flagship multidisciplinary institutions that set standards for teaching and research.

Option C:
The policy does not suggest replacing all existing colleges with a single mega-university; instead, it promotes a diverse ecosystem of HEIs.

Option D:
Focusing only on sports-related education would neglect the multidisciplinary character and research emphasis that define MERUs in NEP 2020.

Domain names such as “jrfnet.com” are human-friendly labels, while IP addresses are numerical identifiers used by routers and hosts. The Domain Name System (DNS) maps each domain name to its corresponding IP address so that when users type the name, the network can route packets to the correct server.

Option A:
This option correctly explains that DNS translates readable domain names into numerical IP addresses. Users work with names, but machines rely on the mapped IP numbers for routing packets on the Internet.

Option B:
This statement is false because domain names and IP addresses have different formats and purposes. A domain like “jrfnet.com” is not the same string as its numeric address, and the two are not interchangeable.

Option C:
Domain names are specifically designed to identify online resources such as websites, mail servers and other services. They are not labels for offline printed books, so this option misunderstands their role.

Option D:
IP addresses are stored in devices and routing tables and are actively used in communication. They are not just written on paper, so claiming they exist only on paper is incorrect.

Interactional models portray communication as a two-way process in which messages go back and forth between sender and receiver,with feedback forming a circular loop. The roles of sender and receiver alternate over time. The stem emphasises circular exchange and feedback,which are features of the interactional model.

Option A:
Linear models show one-directional flow from sender to receiver and do not include feedback loops in the same way.

Option B:
One way communication is essentially linear and does not capture the interactive nature highlighted in the stem.

Option C:
Transactional models extend interactional ideas by viewing participants as simultaneous senders and receivers,not simply alternately sending messages. While related,they stress simultaneity more than simple circularity.

Option D:
Interactional models help explain classroom question–answer sequences where roles of speaker and listener keep changing,making option D the best answer.

The PM SuryaGhar scheme proposes capital subsidies and financing support for rooftop solar systems on one crore households. By enabling families to generate their own power and receive up to 300 units of free electricity per month, it can lower electricity bills and reduce reliance on coal-based generation. The scheme also turns citizens into active participants in the energy transition, promoting a more decentralised and just renewable-energy system.

Option A:
This option is incorrect because the scheme focuses on solar, not fossil-fuel generators.

Option B:
This option correctly summarises how rooftop solar can simultaneously advance social welfare, climate mitigation and citizen empowerment.

Option C:
Benefits are targeted at households, not limited to large industries; industrial policies exist in separate programmes.

Option D:
The scheme builds upon, rather than dismantles, the idea of distributed generation and net-metering; it encourages rooftop solar adoption.

Statement A is correct since with equal maxima the candidate corresponding to the larger ratio part has the higher score. Statement C is true because when group sizes differ, the overall average must weight each group average by its size. D is also correct since percentages place different exams on a common scale and make comparisons meaningful. E is correct because ratios and percentages adjust for different totals and show relative performance better than raw marks alone. B is false because simply averaging group means without considering sizes can give wrong overall values, so A, C, D and E only are correct.

Option A:
Option A is incomplete; although it lists A and C, it omits D and E and thus fails to acknowledge the role of percentages and relative measures in comparing performance. As a result, it does not give the full conceptual picture required.

Option B:
Option B is also incomplete because it leaves out E and includes only A, C and D, so it does not stress the comparative advantage of ratios and percentages over raw scores in unequal situations.

Option C:
Option C is wrong because it includes only C, D and E and omits A, losing the simple but important fact that the greater ratio component corresponds to higher marks under equal maxima. The combination is therefore not fully correct.

Option D:
Option D is correct because it brings together the ideas of ratio comparison, weighted averaging and the usefulness of percentages and relative measures, while excluding B, which misapplies the averaging rule. It mirrors the reasoning needed for NET data interpretation problems on exam marks.

Ecological succession describes the orderly process of community change in which different species colonise,establish and are replaced over time. This process often leads to a more complex and stable climax community suited to local conditions. The stem outlines exactly this gradual and sequential change,so succession is the correct term.

Option A:
Succession may begin with pioneer species on bare substrate and progress through several seral stages. It reflects both biotic interactions and environmental modifications. Because the question refers to these temporal changes towards a climax, this option fits perfectly.

Option B:
Inversion is a meteorological term related to temperature profiles in the atmosphere and has little to do with community species composition. Therefore it does not match the ecological process described.

Option C:
Competition is an interaction between species or individuals for limited resources. While it influences succession, it is only one mechanism and not the overall process itself. Hence it cannot fill the blank accurately.

Option D:
Eutrophication involves nutrient enrichment of water bodies leading to excessive plant growth and oxygen depletion. It is a specific form of ecosystem change,not the general sequence of community development referred to in the stem.

The sequence is generated by aₙ = n⁴ + n² − n for n starting from 1. Substituting n = 1, 2, 3, 4 and 5 gives 1+1−1 = 1, 16+4−2 = 18, 81+9−3 = 87, 256+16−4 = 268 and 625+25−5 = 645, which matches the given series exactly. For n = 6 we compute 6⁴+6²−6 = 1296+36−6 = 1326. Thus 1326 is the only value that preserves this quartic-plus-quadratic-minus-linear pattern.

Option A:
Option A, 1315, is close but not equal to 6⁴+6²−6. It would require subtracting 11 from the value dictated by the formula only for the sixth term. Such an adjustment is not supported by the earlier behaviour of the series and therefore makes option A incorrect.

Option B:
Option B, 1320, differs by 6 from the formula’s result and also does not satisfy n⁴+n²−n when n = 6. Choosing 1320 would arbitrarily reduce the correct term and break the functional rule connecting all terms. Hence this option cannot represent the correct continuation.

Option C:
Option C, 1323, is still not equal to 1296+36−6 and has no direct expression in terms of the established rule. It lies between some candidate values but does not come from the defined algebraic pattern. Therefore option C is not logically consistent with the observed sequence.

Option D:
Option D, 1326, matches exactly the output of the formula for n = 6. It continues the same combination of quartic, quadratic and linear components that produced all previous terms. Because this value arises naturally from the rule without modification, 1326 is the correct next term in the series.

A non-directional hypothesis asserts that two groups will differ or that a relationship exists but does not indicate the expected direction of the difference. It leaves open whether one group will score higher or lower than the other. In statistical testing, this type of hypothesis is usually examined with a two-tailed test because deviations in either direction are considered. Therefore, the form described in the stem is a non-directional hypothesis.

Option A:
A causal hypothesis specifically suggests cause–effect relations rather than merely any difference, and may or may not be directional, so it does not exactly capture the idea of leaving direction unspecified.

Option B:
A non-directional hypothesis is appropriate when theory or prior research is insufficient to predict which group will outperform the other, but evidence suggests that some difference is likely. This aligns with the stem, which notes that difference is predicted without stating which group is superior, making this option correct.

Option C:
A descriptive statement outlines characteristics of a single group or situation without comparing groups, so it is not about predicting differences at all. Hence, it cannot complete the stem.

Option D:
The null hypothesis states that there is no significant difference between groups, directly contradicting the assumption of a difference expressed in the stem. Thus, null is not the correct completion.

Statements A and B correctly describe the length of non-leap and leap years and the divisibility rule used to identify leap years. Statement C is true because the weekly cycle repeats every 7 days, and E is also correct as calendar questions usually count odd days from a known reference day. Statement D is false because odd days are calculated modulo 7, not modulo 5. Therefore, the combination A, B, C and E only is correct.

Option A:
Option A is incomplete because it omits E and therefore misses the practical step of accumulating odd days from a reference, which is crucial for solving day-of-week problems. Without E, the method is not fully described.

Option B:
Option B is wrong as it includes D, which uses modulo 5 instead of modulo 7, and so miscalculates odd days. This incorrect rule makes the entire option unacceptable.

Option C:
Option C is incomplete since it leaves out A and B, thereby not explicitly stating the year-length facts and leap-year rule, even though it contains two true statements.

Option D:
Option D is correct because it gathers all the true statements and excludes D, the incorrect modulus rule, giving a complete and accurate picture of odd-day calculations in calendar questions.

Statements A, B and D accurately describe responsible handling of digital resources, whereas C encourages plagiarism. Citations and DOIs help readers locate original sources and acknowledge authors, and reference managers simplify correct formatting. Access being free does not remove the obligation to credit sources, so C is not acceptable. The correct combination is therefore A, B and D only.

Option A:
Option A is correct because it combines all the true statements that reflect ethical and practical aspects of digital referencing and excludes the permissive view in C. It matches academic standards emphasised in research methodology and ICT use.

Option B:
Option B is incomplete because it includes only A and B and omits D. Recognising DOIs as persistent identifiers is important for locating and citing digital scholarly work, so excluding D gives a partial answer.

Option C:
Option C is incomplete because it lists only B and D and leaves out A. Statement A contains the central ethical rationale for citations and should not be omitted.

Option D:
Option D is incorrect because it treats all four statements as correct and hence accepts C. Since C normalises copying without attribution, this option conflicts with academic integrity.

Statements A, B and C accurately present content analysis as a systematic procedure applied to various materials, conducted quantitatively or qualitatively and based on explicit coding schemes. Statement D is false because digital media, social media posts and websites are common targets of content analysis. Statement E is also false since open-ended questionnaire responses are often coded and analysed using this method. Therefore, the option including A, B and C only is correct.

Option A:
Option A is incomplete because it omits C and thus fails to mention the need for explicit coding categories and rules, which are central to ensuring consistency and reliability in content analysis.

Option B:
Option B is incorrect because it leaves out A, not explicitly stating that the method involves systematic examination of content, which is part of its definition.

Option C:
Option C is correct as it combines all three crucial aspects: systematic focus on content, dual quantitative/qualitative possibilities and reliance on clear coding schemes. It excludes D and E, which narrow the scope of content analysis wrongly.

Option D:
Option D is wrong because it includes E, the claim that open-ended responses cannot be analysed in this way, and omits B, failing to acknowledge both quantitative and qualitative variants of content analysis.
