UGC NET Questions (Paper – 1)

A cross-sequential design involves selecting multiple cohorts of different ages and following them over time, thus combining features of cross-sectional and longitudinal designs. It allows researchers to disentangle age effects, cohort effects and time-of-measurement effects more effectively than using either approach alone. This design is particularly useful in developmental research. Because the stem describes studying several cohorts over time using both cross-sectional and longitudinal elements, cross-sequential design is the correct term.

Option A:
Cross-sectional designs collect data from different age groups at a single point in time, providing a snapshot but not tracking changes within individuals. They do not incorporate repeated measurement over time for the same cohorts. Thus, cross-sectional is not the best completion here.

Option B:
Longitudinal designs follow the same group of participants over an extended period but do not necessarily include multiple age cohorts at the outset. They capture intra-individual change but may confound age and cohort effects. The stem, however, refers to combining several cohorts and following them, which is distinctive of cross-sequential designs.

Option C:
Cross-sequential designs reduce some limitations of purely longitudinal or cross-sectional approaches by allowing researchers to compare patterns across cohorts and time. This structure matches the description in the question precisely, confirming cross-sequential as the appropriate answer.

Option D:
Time series designs involve repeated measurements of a single group over time, often in quasi-experimental contexts, but they usually do not include multiple distinct age cohorts studied concurrently. Therefore, time series is not the correct term for the design described.

Hetu is the middle term or reason whose presence in the paksha, together with known vyapti, justifies the conclusion that the sadhya is also present there. In the classic example, smoke functions as hetu for fire on the hill. A proper hetu must satisfy specific conditions to avoid fallacies. Therefore the inferential sign referred to in the stem is called hetu.

Option A:
Option A, paksha, is the subject in which the hetu and sadhya are discussed and does not itself function as the reason for the conclusion. Confusing the subject with the middle term would obscure the structure of inference.

Option B:
Option B is correct because hetu explicitly names the factor that serves as logical ground for the sadhya. Nyaya analysis of inference revolves around whether a proposed hetu genuinely exhibits vyapti with the probandum.

Option C:
Option C, sadhya, is the goal or probandum to be established and stands as the consequent of the argument, not the evidential basis.

Option D:
Option D, drstanta, is the illustrative example used to clarify the relation between hetu and sadhya and is distinct from the actual reason located in the paksha.

In hexadecimal, the letters A through F represent decimal values 10 through 15. Since 15 is the highest value represented by a single hex digit, it maps to F. Therefore, the hexadecimal representation of decimal 15 is F₁₆.

Option A:
Option A, E, represents decimal 14, which is one less than 15. It is close but not equal to the required value.

Option B:
Option B, D, stands for decimal 13 in hexadecimal notation. This is smaller than 15 and so cannot be correct.

Option C:
Option C, B, corresponds to decimal 11. It is further away from 15 and therefore not suitable.

Option D:
Option D is correct because F is defined as the symbol for decimal 15 in the hexadecimal system. This mapping is standard and widely used in memory and color code representations.

The holistic, 360-degree progress card proposed by NEP 2020 is meant to reflect multiple perspectives. It therefore includes inputs from teachers, the student’s own self-assessment, peer feedback and, where appropriate, parents, making assessment more comprehensive and growth-oriented.

Option A:
Relying only on external examiners gives a very limited and occasional snapshot and does not match the continuous, multi-source assessment model described in NEP.

Option B:
This option is correct because it lists the key stakeholders—teachers, learners, peers and sometimes parents—who together contribute to the new holistic progress card.

Option C:
Making only principals responsible for all student-level assessment is neither practical nor aligned with the classroom-based assessment emphasis of the policy.

Option D:
District-level inspectors focus on system monitoring and do not provide the regular, close-range feedback envisioned for individual students’ progress cards.

Statements A, B, C and E are correct, whereas D and F are false. A gives the basic structure of an argument, while B and C clarify how explanations and illustrations function differently from proof. E is right that exam performance improves when one can separate arguments from mere description or example. D is wrong because “because” and “therefore” often signal reasoning, and F is wrong because a lone assertion with no supporting reasons is not an argument. So A, B, C and E only is the correct combination.

Option A:
Option A is incomplete since it omits E, which correctly stresses the exam importance of distinguishing arguments from non-arguments. Although A, B and C explain the concepts, without E the practical UGC NET angle is missing. Therefore A, B and C only cannot be accepted.

Option B:
Option B is correct because it brings together conceptual clarity about arguments, explanations and illustrations along with their relevance to exam questions. It avoids D and F, both of which misclassify reasoning signals and unsupported statements. This makes the option fully consistent with reasoning pedagogy.

Option C:
Option C is wrong as it includes D, which incorrectly reclassifies all “because” or “therefore” uses as description, and it omits A, the core definition of an argument. Without A, the option fails to define its central concept. Therefore B, C, D and E only cannot be chosen.

Option D:
Option D is incorrect because it includes F, treating unsupported statements as arguments, and it also omits B. This option mischaracterises both explanation and argument and leaves out an important conceptual distinction. As a result, A, C, E and F only is not a valid answer.

Everyday counting and most written arithmetic activities use the decimal system. This system is based on ten symbols, 0 through 9, and is therefore called a base-10 or decimal system. Historically it is linked to humans having ten fingers, which made grouping in tens natural. Thus, the decimal system is the usual human counting system.

Option A:
Option A is correct because decimal notation underlies standard arithmetic taught in schools and used in currencies and measurements. Its base 10 structure is reflected in common units such as tens, hundreds and thousands. This makes it the default system for human counting.

Option B:
Option B, binary, is primarily used inside digital circuits and computer processors where two distinct states are easy to implement. It is not the system used in ordinary human counting in daily life.

Option C:
Option C, octal, uses base 8 with digits 0 to 7 and is occasionally used as a shorthand for binary. However, it is not the dominant system for general human activities.

Option D:
Option D, hexadecimal, is a base-16 system widely used in computing for compact representation of binary values, but it is not used for routine human counting tasks.

Mission LiFE is conceptualised as a mass movement to encourage individuals and communities to adopt mindful and deliberate utilisation of resources. It aims to reduce wasteful consumption, promote sustainable habits and align everyday choices with environmental protection. By focusing on behaviour change, it links climate action with lifestyle, making every citizen a stakeholder in development that respects planetary limits. This approach integrates environmental responsibility into daily life rather than treating it as a separate technical domain. (NITI Aayog)

Option A:
This option correctly captures the central idea of Mission LiFE, which emphasises changing lifestyles and consumption patterns to reduce environmental footprints. It recognises that climate and environmental challenges are not only about technology and policy but also about how people live, consume and conserve. The focus is on positive, practical actions that ordinary people can take without sacrificing development aspirations.

Option B:
This option is incorrect because Mission LiFE is not about expanding fossil-fuel based thermal power; in fact, it encourages reduced dependence on carbon-intensive choices. Large thermal power projects may be part of the overall energy mix today, but they are not the focus of LiFE’s behavioural campaign. Linking LiFE only with thermal capacity would ignore its demand-side orientation.

Option C:
Direct cash transfers may be used in some welfare schemes, but LiFE is built around nudging and enabling sustainable behaviours rather than unconditional cash benefits. The initiative stresses awareness, community mobilisation and enabling green choices, not income support independent of environmental performance. Therefore, this description misses the programme’s core philosophy.

Option D:
Replacing environmental laws with purely voluntary corporate codes would weaken regulatory safeguards and is not the intent of LiFE. The initiative complements, rather than substitutes, environmental regulations by mobilising citizens and communities. Its emphasis is on shared responsibility and lifestyle shifts, not deregulation.

Statements A, B, C and E are correct because standards exist for air, water and noise, and regular monitoring is required to see whether actual conditions meet these limits. Statement D is false, since even legally binding standards require regulatory institutions, penalties and compliance mechanisms to be effective. Statement F is false too because public disclosure of data supports transparency and can create pressure for better enforcement. Therefore, the set that keeps A, B, C and E while excluding D and F is correct.

Option A:
Option A is incorrect as it omits E and thereby ignores the crucial role of monitoring in making standards meaningful. Without E, there is no way to check compliance systematically.

Option B:
Option B is incorrect since it leaves out C, thus failing to mention noise standards, which are part of environmental quality frameworks, especially in urban areas.

Option C:
Option C is incorrect because it includes D, which wrongly suggests that standards never need enforcement mechanisms. Including D mixes a clearly false claim with correct statements.

Option D:
Option D is correct as it retains all the true statements about what standards are and how they are applied, while rejecting the idea that enforcement and public information do not matter.

Environmental education seeks to build knowledge,values and attitudes that lead to caring and responsible action for the environment. Developing awareness and concern is foundational because people must first understand and care about issues before they change behaviour. The stem explicitly mentions positive orientation and responsible behaviour,which comes from awareness and concern. Hence Option B is correct.

Option A:
Apathy is lack of concern,which is opposite to the goal of environmental education.

Option B:
Awareness and concern directly support responsible environmental behavior and match the aim described in the stem.

Option C:
Exploitation skills contradict the stewardship and sustainability focus of environmental education.

Option D:
Purely commercial skills focus on profit and do not match the environmental responsibility goal stated.

Statements A, B and C correctly distinguish LAN, WAN and MAN by their geographical coverage. LANs serve limited areas like buildings, WANs can span entire countries or continents, and MANs typically cover metropolitan regions. Statement D is false because LANs can be implemented using wired, wireless or mixed technologies. Thus, the combination that includes A, B and C but excludes D is the correct answer.

Option A:
Option A is incorrect because it mentions only A and B as correct and omits C. While A and B are true, statement C is also correct in associating MAN with city-wide networks. Leaving out a true statement means this option does not present the full set of correct statements.

Option B:
Option B is correct because it brings together A, B and C, all of which are accurate descriptions of common network types. It rightly excludes D, which wrongly claims that LANs must always be wireless. Therefore this option aligns with standard ICT classifications of networks by scope.

Option C:
Option C is incorrect because it includes D alongside B and C. Although B and C are true, D is false because LANs may be wired, wireless or a combination. Including a false statement invalidates the combination.

Option D:
Option D is incorrect because it assumes all four statements are correct. Statement D misrepresents the nature of LAN technologies and should not be included among correct statements. A valid answer must exclude that incorrect statement.

Statements A, B and D are correct, whereas C and E are incorrect. A is true because clickers or apps can capture students’ answers in real time. B is true as forums allow questions and interaction outside class. D is true since multimedia simulations help visualise difficult ideas. C is false because equal participation still requires careful facilitation, and E is false because ICT supplements rather than replaces teacher–student dialogue. Hence, A, B and D only is the correct combination.

Option A:
Option A presents A, B and D, bringing together instant feedback, extended communication and visual support, and omitting C and E, which exaggerate what technology can do. Since all statements in this option are correct and the false ones are excluded, A, B and D only is the right answer.

Option B:
Option B lists A and B only and leaves out D, failing to mention the explanatory potential of video and simulations for abstract concepts. As a result, A and B only does not fully address the range of ICT tools mentioned in the question.

Option C:
Option C combines B, D and E, but E wrongly claims that dialogue becomes unnecessary when ICT is used. Including this extreme view makes B, D and E only an invalid answer.

Option D:
Option D groups A, C and D, but C is incorrect because participation patterns are not automatically equal in technology-rich settings. Consequently, A, C and D only cannot be accepted.

Statements A, B and C are correct, while D is the only wrong statement. A is correct because open-ended questions encourage learners to think beyond simple facts and explore higher-order responses. B is correct as an exclusive focus on recall questions can limit development of analytical skills. C is correct because providing wait-time after posing a question allows more learners to formulate thoughtful responses. D is wrong since teachers should usually resist answering their own questions immediately; instead they should allow students time to respond.

Option A:
Option A is incorrect because it identifies A and B as the wrong statements. In fact both A and B are sound recommendations: open-ended questions do stimulate higher-order thinking, and reliance only on recall questions is indeed limiting. Since neither A nor B is wrong, this combination cannot represent the set of wrong statements.

Option B:
Option B is correct because it singles out D only as the wrong statement. D suggests that teachers should always answer their own questions immediately, which contradicts the idea of giving learners time to think and respond. By excluding A, B and C, which are all true, this option correctly captures the single wrong strategy described in the list.

Option C:
Option C is incorrect because it lists B and D as wrong statements. While D is indeed wrong, B accurately warns that exclusive use of recall questions can limit higher-order thinking. Treating B as wrong misrepresents the effects of such questioning, so this combination is not acceptable.

Option D:
Option D is incorrect because it treats A, B and D as a set of wrong statements. As explained, A and B are true statements about the value of open questions and the limits of recall-only questioning. Including these correct statements alongside D in the supposed wrong set makes this option overinclusive.

Badhita hetu is considered defective because its alleged vyapti cannot stand in the face of more authoritative evidence. For example, a reason that implies that fire is cold is immediately overturned by direct perception of heat. In such cases, even if the formal structure of the inference looks acceptable, the underlying universal relation is invalidated. Nyaya therefore treats the reason as defeated or badhita.

Option A:
Option A, savyabhicara, concerns irregularity of a reason across instances and not explicit conflict with a stronger pramana. The issue there is empirical deviation, not direct refutation.

Option B:
Option B, asiddha, involves non-establishment of the hetu in the paksha rather than its being contradicted at the level of vyapti.

Option C:
Option C is correct because badhita literally means "defeated" and is used when a proposed relation is annulled by superior sources like perception or scripture. It shows the need for harmony among pramanas in Nyaya.

Option D:
Option D, viruddha, denotes a reason that proves the opposite conclusion on its own, without needing external refutation, which is a different kind of defect.

Statements A and B capture that validity is about form, not actual truth of premises. Statement C correctly defines the fallacy of affirming the consequent. Statement E is true because many reasoning questions test the distinction between validity and soundness. Statement D is false since a sound argument is valid and has true premises. Hence A, B, C and E only are correct.

Option A:
Option A is incomplete because it omits E (importance of the distinction) even though A, B, C are true.

Option B:
Option B is incomplete because it omits B (valid with false premises) and also does not include all correct statements together.

Option C:
Option C is correct because it gathers all true statements and excludes D, which reverses the condition for soundness.

Option D:
Option D is wrong because it includes D (false), even though it contains some true statements.

Mass communication involves transmitting messages from a single source to large,heterogeneous and dispersed audiences through technological media. A television station sending programmes to millions simultaneously is a classic one to many pattern. Thus the situation in the stem clearly represents mass communication.

Option A:
Interpersonal communication is limited to a few people in direct interaction and cannot describe a nationwide TV broadcast.

Option B:
Mass communication relies on institutional senders and technical channels like TV towers,satellites and cable networks,making this option correct for the described scenario.

Option C:
Group communication involves face to face interaction among a small number of participants,not a mass audience.

Option D:
Intrapersonal communication is internal thinking and has nothing to do with broadcast media.
