UGC NET Questions (Paper – 1)

Schramm's model emphasises that communication is more effective when the fields of experience of sender and receiver overlap. Field of experience includes cultural background,education and prior knowledge. By using familiar language and examples,the teacher deliberately links the message to students' field of experience,so this term correctly completes the stem.

Option A:
When there is high overlap between fields of experience,less explanation is needed and chances of misunderstanding decrease. Adapting content in this way demonstrates audience awareness and aligns fully with Schramm's idea,which supports Option A.

Option B:
Channel is the medium through which the message travels,such as a projector or microphone,and is not the same as the learners' background knowledge.

Option C:
Noise denotes interference that obstructs message transmission,whereas the stem describes a strategy to enhance understanding,not a barrier.

Option D:
Feedback refers to the responses students give after receiving the message,but the question is about pre adapting the message before delivery.

Mixed methods research deliberately combines quantitative techniques such as surveys and experiments with qualitative techniques such as interviews and observations. The purpose is to capitalise on the strengths of both approaches and offset their weaknesses. Integration may occur at the design, data collection, analysis or interpretation stages. Hence, the integrated approach described in the stem is mixed methods research.

Option A:
Historical research focuses on past events using documents and archival sources and may involve qualitative or quantitative analysis but is not defined primarily by integration of the two paradigms in one programme.

Option B:
Experimental research typically uses quantitative methods to test causal hypotheses with manipulation and control. Although qualitative components can be added, the term experimental alone does not imply intentional integration.

Option C:
Mixed methods studies might, for example, use quantitative results to identify patterns and then conduct qualitative interviews to explain those patterns, or they may build instruments from qualitative findings. This purposeful combination of approaches matches the stem, making this option correct.

Option D:
Correlational research examines associations among variables without manipulation and usually remains within a quantitative framework, not integrating qualitative data by design.

Statements A, B, E and F together give a correct overview of open universities. A is true because such universities are designed for learners unable to attend regular classes. B is true since multiple instructional media are used to reach dispersed learners. E is true because open universities explicitly target lifelong learning needs of working adults and others. F is true as many open universities undertake research projects and community outreach. C is false because degree and credit-bearing programmes are a central part of their mandate, and D is false because they are authorised to offer degrees subject to regulatory approval.

Option A:
Option A is incorrect because it omits F and thus fails to acknowledge the research and community outreach roles that some open universities undertake alongside teaching.

Option B:
Option B is incorrect because it includes D, which wrongly claims that degree programmes are prohibited, and therefore mixes correct and incorrect statements in one combination.

Option C:
Option C is correct as it includes exactly the true statements A, B, E and F and excludes C and D, which misrepresent the credit and degree-granting nature of open universities.

Option D:
Option D is incorrect because it incorporates C, a false statement that restricts open universities to non-credit offerings, and therefore does not reflect the full scope of their academic mandate.

In this series each term is a four letter group where the distance between consecutive letters inside a group is fixed. From BGLQ to CHMR to DINS to EJOT, every letter in each position moves forward by one step in the alphabet, so the vertical columns form simple increasing sequences. Applying the same shift to EJOT, E goes to F, J goes to K, O goes to P and T goes to U, giving FKPU. No other option arises from this consistent column wise movement with the same internal spacing, so FKPU is the correct continuation.

Option A:
Option A maintains the internal structure of the earlier groups because the gaps between F, K, P and U match those seen in BGLQ, CHMR, DINS and EJOT. It also continues each column sequence smoothly, for example the first letters B, C, D and E are followed naturally by F. Since it respects both the within group spacing and the across group progression, FKPU fits perfectly into the series.

Option B:
Option B, GLQV, looks similar but pushes every letter two steps ahead of EJOT instead of one, which breaks the steady one step advancement seen earlier. As a result, its letters no longer align with the vertical sequences formed by the previous groups. Because it distorts the regular shift pattern, GLQV cannot be the correct next term.

Option C:
Option C, FJPV, changes the differences between letters inside the group so that they do not match the constant spacing of the given series. It also mixes letters that do not arise from shifting EJOT uniformly forward. This double mismatch in spacing and transformation makes FJPV an invalid continuation.

Option D:
Option D, EJPU, keeps the first two letters unchanged and alters only the last two, whereas the pattern clearly moves all four letters together. Its internal distances differ from those of the original terms as well. Therefore EJPU does not satisfy the rule governing the series.

Ergonomics is concerned with adapting tools and environments to human capabilities and limitations. In ICT, this includes arranging desks, chairs and devices to prevent repetitive strain injuries and eye fatigue. Proper ergonomic design supports long term healthy use of computers. Thus, the practice described is ICT ergonomics.

Option A:
Option A is correct because ergonomics explicitly addresses physical design for comfort and efficiency in computer use.

Option B:
Option B, encryption, deals with secure encoding of data and is unrelated to workstation layout.

Option C:
Option C, netiquette, concerns online behaviour rules, not physical posture or hardware placement.

Option D:
Option D, debugging, is the process of finding and fixing errors in software code.

Statements A, C, D and E are correct because source segregation improves material quality, household sorting reduces contamination, informal workers enhance recovery, and awareness plus system design keep segregation going. Statement B is false since mixing waste reduces the quality of recyclables and makes processing harder. Statement F is false because proper segregation helps waste-to-energy plants by removing wet or inert materials that lower calorific value. Therefore, the combination A, C, D and E only is correct.

Option A:
Option A is incorrect as it omits D and E, thereby ignoring the significant roles of informal workers and supportive systems in making segregation effective and sustainable.

Option B:
Option B is incorrect because it leaves out E and still fails to mention the importance of public awareness. It also does not include all relevant correct statements about actors and systems involved.

Option C:
Option C is correct since it recognises technical, behavioural and institutional aspects of segregation while rejecting claims that mixing improves efficiency or that segregation is irrelevant for waste-to-energy facilities.

Option D:
Option D is incorrect as it includes F, which wrongly dismisses the relevance of segregation for energy recovery, and it omits A, which is the core statement about what segregation does.

Let the original numbers be 4x and 7x. After adding 8 to each, the new numbers are 4x + 8 and 7x + 8 and their ratio is 5:8. So (4x + 8)/(7x + 8) = 5/8. Cross-multiplying gives 8(4x + 8) = 5(7x + 8), which simplifies to 32x + 64 = 35x + 40 and then to 3x = 24, so x = 8. The original numbers are 32 and 56, and the larger is 56.

Option A:
Option A, 40, does not appear as either 4x or 7x when x = 8 and would not preserve the required ratio 4:7 together with its pair. If we assume 40 as the larger number, the smaller would be less than 40, leading to a ratio different from 4:7 and a different transformed ratio after adding 8. Thus 40 is inconsistent with the given conditions.

Option B:
Option B, 48, might be guessed by partial calculation but does not satisfy the equation (4x + 8)/(7x + 8) = 5/8 when treated as the larger number. With 48 as the larger term, the corresponding smaller term from ratio 4:7 would be non-integral or lead to a different new ratio after adding 8. Hence 48 is not correct.

Option C:
Option C is correct because with x = 8 the original numbers are 4 × 8 = 32 and 7 × 8 = 56, which are in the ratio 4:7. After adding 8, we get 40 and 64, whose ratio is 40:64 = 5:8, exactly matching the condition. This confirms 56 as the unique value for the larger original number.

Option D:
Option D, 64, is the larger number after the increment rather than before it in the correct solution. Treating 64 as the original larger number would produce a much bigger value after adding 8 and the resulting ratio would no longer become 5:8. Thus 64 does not align with the stated transformation.

The auditory system,which includes the ear and related neural pathways,is directly affected by continuous exposure to high noise levels. Such exposure can lead to temporary or permanent hearing loss,tinnitus and other auditory disorders. The stem explicitly mentions damage from environmental noise,so the auditory system is the correct answer. Therefore Option C is appropriate.

Option A:
Digestive problems can sometimes be indirectly influenced by stress but are not the primary health outcome of noise exposure. The main clinical concern with noise pollution is hearing impairment rather than digestive system disorders,so Option A is not accurate here.

Option B:
The skeletal system involves bones and joints and is generally not affected by noise levels in the environment. Noise does not directly weaken or damage bones,so this option does not match the primary impact described in the question.

Option C:
The auditory system is highly sensitive to sound pressure levels and duration of exposure. Occupational and urban noise regulations are designed specifically to protect this system from long term damage. This explanation fits the content of the stem.

Option D:
The reproductive system is not directly harmed by typical environmental noise levels,although extreme stress can influence many body systems. However,this is not the main issue addressed in noise pollution studies,so Option D is not the best choice.

The correlation function of media involves interpreting events,explaining their significance and prescribing responses. Editorials do exactly this by analysing news and guiding public opinion. Therefore they primarily serve the correlation function.

Option A:
Surveillance refers to reporting events and conditions,which is more descriptive than interpretive.

Option B:
Correlation is about interpretation,context and guidance for response,which is exactly what editorials provide.

Option C:
Entertainment focuses on amusement and enjoyment,not serious interpretation of issues.

Option D:
Diversion provides escape/relaxation rather than analysis and guidance.

Action research is carried out by practitioners such as teachers to solve immediate problems and improve their own practice. It typically involves cycles of planning, acting, observing and reflecting within a specific context, like a particular class. The results are context-bound but highly relevant for local decision-making. Therefore, teacher-led inquiry aimed at improving instruction in a specific classroom is best described as action research.

Option A:
Basic research is conducted primarily to develop theory and expand general knowledge, often without direct concern for immediate practical problems in a single classroom. It is usually more abstract and less context-specific than the situation described.

Option B:
Action research empowers teachers to systematically try new strategies, collect evidence about their effectiveness and adjust their practice accordingly. It integrates reflection with empirical data collection, making it suitable for addressing classroom difficulties. Because the stem highlights improvement of instructional practices by a teacher, this option is correct.

Option C:
Historical research focuses on events and developments in the past using documents and archival sources. It does not primarily aim to improve current teaching practice in a specific classroom setting.

Option D:
Descriptive research seeks to portray the characteristics of a population or phenomenon as it currently exists but may not necessarily involve cycles of intervention and reflection by the practitioner. Thus, it does not fully match the form of inquiry mentioned.

The GBF recognises that conserving and restoring biodiversity at scale requires both new funding and reformed economic incentives. It therefore calls for mobilising at least US$200 billion annually from public and private sources for biodiversity-related activities. Simultaneously, it urges countries to identify and reform subsidies harmful to biodiversity by at least US$500 billion per year, freeing resources for positive incentives. (Convention on Biological Diversity)

Option A:
This option correctly combines the two headline numbers on finance mobilisation and harmful subsidy reduction that appear in GBF targets.

Option B:
This option is incorrect because the framework emphasises greater support to developing countries, not withdrawal of funding.

Option C:
Increasing harmful subsidies would contradict the GBF’s explicit goal of reducing such incentives.

Option D:
The framework covers all ecosystems, including wetlands, grasslands and oceans; it is not limited to forests.

Feedback in communication is the receiver's response that goes back to the sender,indicating how the message was understood. When students ask questions after a lecture,they reveal which parts are clear and which are confusing. This information helps the teacher evaluate the effectiveness of teaching. Therefore,these responses function as feedback.

Option A:
Noise is any interference that distorts the message and reduces clarity,such as external sound or technical problems. Students' questions are not interference but purposeful responses. Hence this option is not appropriate here.

Option B:
Feedback allows the teacher to modify explanations,provide more examples or change pace based on student needs. Since the stem focuses on responses after a lecture,feedback is the correct concept.

Option C:
Redundancy involves repetition of information for clarity,not the receiver's reactions.

Option D:
Context refers to physical and social setting but does not itself indicate how the message was received.

Academic corruption refers to unethical and illegal practices in education, including bribery for admissions, manipulation of marks and awarding degrees without meeting academic standards. These actions undermine the integrity of higher education systems. The stem lists precisely such irregularities, so “corruption” is the correct term to describe them, making Option B appropriate.

Option A:
Corruption in higher education erodes public trust, damages the reputation of institutions and disadvantages honest students and staff. It is a serious governance challenge highlighted in discussions of the Higher Education System, aligning with the context of the question.

Option B:
Excellence refers to high quality and ethical behaviour, which is the opposite of what is being described. Hence, Option A is clearly incorrect.

Option C:
Innovation involves creative improvements or new practices, not the unethical shortcuts listed in the stem, so Option C is not suitable.

Option D:
Service suggests positive contribution to students and society, whereas the stem describes harmful practices, making Option D inappropriate.

The task is to identify the wrong statement about distance education regulation and quality. Statement A is correct because distance programmes must adhere to norms of designated regulators. Statement C is true as quality assurance covers learner support services, quality of materials and fair evaluation processes. Statement D is also correct since guidelines are designed to maintain minimum acceptable standards. Statement B is wrong because universities generally need approval or recognition to launch distance programmes. Therefore, B alone is the wrong statement.

Option A:
Option A is incorrect because it groups A and B as wrong, which would imply that compliance with regulatory norms is incorrect. In fact, A properly describes a legal requirement for distance education programmes.

Option B:
Option B is incorrect because it combines B and C as wrong. While B is wrong, C accurately identifies key dimensions of quality in distance education. Misclassifying C undermines the understanding of quality assurance.

Option C:
Option C is correct because it isolates B as the only statement that contradicts regulatory practice. It affirms the need for approvals and recognises that other statements describe genuine quality and regulatory features.

Option D:
Option D is incorrect because it treats all four statements as wrong. That would reject regulatory norms, quality assurance and minimum standards, which is clearly inconsistent with actual policy.

Statements A, B, C and E are correct because they describe the multi-dimensional nature of food security, the influence of climate change, the role of sustainable practices and the contribution of diversification to resilience. D is false since food loss and waste directly affect availability and access, and F is false because agricultural policies must consider environmental sustainability to avoid long-term degradation. Therefore, the correct combination is A, B, C and E only.

Option A:
Option A is incomplete, because it omits E and thus underplays the importance of diversification and resilience strategies for farming households. It focuses only on definitions and broad drivers.

Option B:
Option B is incorrect as it includes D, claiming post-harvest losses are irrelevant. This contradicts evidence that reducing losses and waste is a major lever for improving food security without expanding production.

Option C:
Option C is correct since it collects all four true statements while excluding D and F, which ignore key aspects of food systems and sustainability. It provides a comprehensive view of food security in a changing environment.

Option D:
Option D is incorrect because it accepts F and omits A, thereby denying the need for environmentally sensitive agricultural policies and neglecting the standard four-pillar definition of food security.
