UGC NET Questions (Paper – 1)

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.

Eco taxes and subsidy reforms work by altering financial incentives so that environmentally harmful activities become more expensive and cleaner alternatives more attractive. These tools are classic examples of economic instruments. The stem explicitly refers to changing prices through taxes and subsidies,so “economic” instruments is the correct description. Option B is therefore right.

Option A:
Command and control instruments rely on regulations that set standards or limits and enforce compliance through penalties. They do not primarily operate by changing prices,so Option A is not suitable here.

Option B:
Economic instruments internalise environmental costs into market decisions by adjusting taxes,subsidies or tradable permits. This aligns exactly with the function described in the question.

Option C:
Informational instruments focus on providing data,labels or awareness to influence behaviour. While useful,they do not directly change price structures in the way eco taxes and subsidy removal do.

Option D:
Voluntary instruments involve self regulation or agreements without legal compulsion. They may accompany economic measures but are not defined by price changes,so Option D does not fit.

Statements A, B, D and E capture the main purposes of a review of related literature, while statement C is incorrect. Statement A is true because reviewing earlier studies helps to locate gaps in existing knowledge. Statement B is correct since understanding existing work helps the researcher refine the research problem and formulate or adjust hypotheses, and statement D is accurate because knowledge of prior studies prevents unnecessary duplication. Statement E is also true, as review of literature provides theoretical and conceptual frameworks for the study, whereas statement C is false because review is typically conducted before data collection, not only after it.

Option A:
Option A brings together A, B and D but omits E. Although A, B and D are true, excluding E means the important role of literature review in building theoretical and conceptual frameworks is not reflected. Since all four of A, B, D and E are correct, leaving one out makes this option incomplete and therefore incorrect.

Option B:
Option B correctly combines A, B, D and E, which together summarise the key functions of a literature review. It recognises that review helps to identify gaps, refine problems and hypotheses, avoid duplication and build conceptual frameworks. It also implicitly excludes statement C, which wrongly postpones literature review to only after data collection. Because it includes all and only the true statements, this option is the correct answer.

Option C:
Option C groups B, D and E but leaves out A. While B, D and E are true, A is also correct because identifying research gaps is a central reason for conducting a literature review. Omitting A leads to an incomplete specification of the review’s functions, so this option cannot be accepted.

Option D:
Option D includes A, D and E but also incorporates C, which is false. By suggesting that literature review is conducted only after data collection, statement C misrepresents standard research practice. Since this option mixes a false statement with true ones, it does not provide a valid set of correct statements.

Assumptions are implicit or explicit statements that the researcher accepts as true for the purposes of the study without directly verifying them within that study. Examples include assuming that instruments are understood correctly by respondents or that the sampling frame adequately represents the population. These assumptions underpin the design and interpretation of results. Because the stem refers to statements taken as true without direct testing that support the design, it is defining assumptions.

Option A:
Hypotheses are formal, testable statements about relationships between variables and are subjected to empirical verification during the study. They are not accepted as true in advance but are evaluated using data. Therefore, hypotheses do not match the idea of statements accepted without direct testing.

Option B:
Assumptions function as background conditions that need to be plausible for the design and conclusions to be valid. Researchers often state them explicitly so that readers can judge whether they are reasonable. This role aligns precisely with the stem’s description, confirming assumptions as the correct completion.

Option C:
Delimitations are boundaries that define the scope of the study, such as excluding certain populations or contexts. They are conscious choices rather than untested statements about reality. Hence, delimitations is not appropriate here.

Option D:
Recommendations are suggestions for action or further research offered at the end of a study based on its findings. They come after results are obtained and do not serve as pre-existing conditions on which the design rests. Consequently, recommendations cannot complete the stem correctly.

NEP 2020 defines the foundational stage as spanning ages 3–8. It includes three years of pre-school or Anganwadi-based ECCE plus Grades 1 and 2. This grouping reflects research on early brain development and the need for continuous play-based and activity-based learning. It is the base of the 5+3+3+4 structure.

Option A:
This option correctly connects the foundational stage to both ECCE and early primary grades, forming a coherent developmental block.

Option B:
Grade 12 alone is part of the secondary stage, not foundational.

Option C:
Ages 15–18 correspond to the senior secondary part of the secondary stage.

Option D:
Grades 6–8 form part of the middle stage, not foundational.

NEP 2020 stresses that teachers must be able to teach in the language children understand best, especially in the early years. Teacher education should therefore develop skills for rich, interactive teaching in mother tongue/local languages and also build competence in additional languages like English.

Option A:
Option A is incorrect because an English-only focus would undermine NEP’s strong recommendation for mother tongue-based education in early grades.

Option B:
Option B is correct as it reflects NEP’s integrated language vision: effective use of local languages plus capacity to teach additional languages.

Option C:
Option C is incorrect since ignoring language issues would leave teachers unprepared for multilingual classrooms and contradict NEP’s language policy.

Option D:
Option D is incorrect because training teachers merely to translate textbooks word-for-word does not meet the pedagogical goals of meaningful bilingual or multilingual teaching.
