UGC NET Questions (Paper – 1)

The polluter pays principle requires that the costs of pollution control and remediation be borne by those responsible for creating pollution. It aims to internalise environmental externalities into production and consumption decisions. The stem clearly describes the idea that polluters should pay for prevention,control and clean up,so polluter pays is the correct term. This principle underpins many modern environmental policies.

Option A:
The precautionary principle emphasises taking preventive action in the face of scientific uncertainty,but it does not specify who should bear the cost. Therefore it does not directly address the cost allocation issue highlighted in the question.

Option B:
Polluter pays encourages firms to adopt cleaner technologies and avoid wasteful practices,because they face financial responsibility for damage. This aligns well with the demand in the stem that generators of pollution cover associated costs.

Option C:
Subsidiarity is a governance principle stating that decisions should be taken at the lowest effective level,close to affected citizens. It deals with institutional arrangements rather than cost allocation for pollution,so it is not the right answer.

Option D:
Proximity refers to managing waste as close as possible to its source to reduce transport and associated impacts. While related to logistics,it does not capture the core idea that polluters should bear costs,so Option D is not suitable.

Each term is a four-letter consecutive block. Starting letters B(2), F(6), J(10), N(14) increase by +4. Next start is R(18), so the block is RSTU.

Option A:
Option A starts at Q(17), which is only +3 from N, not +4.

Option B:
Option B is correct because R is +4 from N and S,T,U follow consecutively.

Option C:
Option C starts at S(19), which is +5 from N, not +4.

Option D:
Option D starts at O(15), which is +1 from N and also disrupts the forward pattern.

Diagonal communication cuts across both functional departments and vertical levels in an organisation. A registrar normally works in administration,while students belong to academic units. When the registrar emails students directly,bypassing heads,this communication is diagonal. Hence,the stem describes diagonal communication.

Option A:
Grapevine is an informal network based on personal contacts and rumours,not necessarily official emails from administrators.

Option B:
Horizontal communication would be between people at the same level,such as between two registrars or between two student leaders.

Option C:
Upward communication flows from lower to higher levels,such as students writing to the registrar,not the other way round.

Option D:
Diagonal communication can speed up information flow by linking different parts of the organisation,making option D the correct answer.

Mitigation refers to measures taken in advance to reduce the potential adverse impacts of hazards by limiting exposure or vulnerability. Structural interventions like embankments and stronger buildings are classic mitigation tools. The stem lists exactly such measures,so disaster risk mitigation is the correct concept. Therefore Option D is appropriate.

Option A:
Response involves immediate actions during or right after a disaster (rescue,relief),not advance structural measures.

Option B:
Recovery focuses on restoring services and livelihoods after a disaster,not on pre event strengthening.

Option C:
Preparedness includes planning,training and drills; it is about readiness rather than structural risk reduction measures like retrofitting.

Option D:
Mitigation reduces risk before hazards occur through measures such as embankments,shelters and retrofitting,exactly as described in the stem.

A digital library organises and provides access to collections of electronic resources that can be searched and retrieved by users over networks. It often includes digitised versions of print materials as well as born-digital content like e-journals. Advanced search and indexing tools help users locate relevant information quickly. Thus the electronic collection described in the stem is a digital library.

Option A:
Option A is correct because digital libraries extend traditional library services into the online environment, emphasising electronic storage and networked access. The examples of e-books and online journals are core components of such systems.

Option B:
Option B, microfilm store, refers to physical storage of photographic film copies of documents and is not inherently network-accessible. Users typically need specialised readers on site.

Option C:
Option C, print warehouse, suggests physical storage of printed books and journals without the digital access features highlighted in the question.

Option D:
Option D, lecture capture, records teaching sessions but does not by itself constitute a managed collection of varied documents like a library.

In power sector statistics, “non-fossil” generally includes all electricity sources that do not burn fossil fuels. For India, this category typically comprises solar, wind, hydro (both large and small), nuclear and other renewables like biomass and small waste-to-energy projects. Counting all of these together, recent data show that non-fossil capacity has crossed the 50% share mark. This classification is important for tracking progress towards climate and energy targets.

Option A:
This option is incorrect because hydro and nuclear are also non-fossil and are routinely included in official statistics. Limiting the category to only solar and wind understates the share.

Option B:
This option correctly identifies the typical composition of non-fossil capacity in Indian power statistics. It reflects how multiple clean or low-carbon technologies contribute to the overall share.

Option C:
This option is wrong because nuclear alone represents only a small part of India’s capacity. Non-fossil shares rely heavily on renewables as well.

Option D:
Coal, even with carbon capture, is still a fossil fuel and is not classified as non-fossil. Including it would contradict standard reporting practices and climate accounting.

Population density expresses how many people live in a given unit of land area, allowing comparison of how crowded or sparsely populated different regions are.

Option A:
Incorrect, because the share of people in urban areas describes the level of urbanisation, not density itself.

Option B:
Correct, as it defines density directly as people per unit area of land.

Option C:
Incorrect; the rate of natural increase is based on birth and death rates and shows how fast a population is growing, not how it is distributed in space.

Option D:
Incorrect; the average number of children per woman refers to fertility, not density.

Constructivist approaches view learning as an active process in which learners build new knowledge on the foundation of their existing ideas and experiences. Knowledge is not simply transmitted; it is constructed through interaction with the environment, tasks and social discourse. Teachers in this perspective design activities that require learners to explore, question and make meaning. Therefore, the approach described in the stem is the constructivist approach.

Option A:
Behaviourist approaches emphasize observable behaviour changes brought about by stimuli and reinforcement, often downplaying internal mental construction. While they can explain some aspects of learning, they do not focus on learners actively constructing knowledge structures. Thus, behaviourism is not the approach referred to in the question.

Option B:
Traditional lecture approaches typically align with a transmission model where the teacher delivers information and students receive it passively. There is limited emphasis on learners restructuring their own understanding through activity. Consequently, this option does not capture the active, constructive role assigned to learners in the stem.

Option C:
Constructivist approach holds that learners integrate new information with prior knowledge through active engagement. Activities like experiments, discussions and projects allow them to test and refine their ideas. Since the stem explicitly mentions active construction of knowledge through interaction and prior ideas, this option correctly names the approach.

Option D:
Authoritarian approaches stress strict control, obedience and unilateral decisions by the teacher. They tend to restrict learner autonomy and dialogue, which are important for knowledge construction in constructivism. Thus, authoritarian teaching contradicts the philosophy described in the question.

Bluetooth provides low power wireless communication over short distances, typically within ten metres. It is commonly used for connecting peripherals like headphones, keyboards and speakers to phones or computers. The standard is optimised for ease of pairing and moderate data rates rather than long range coverage. Hence, the technology described is Bluetooth.

Option A:
Option A, WiMAX, is designed for broadband wireless access over long distances and is not typically used for personal area connections between nearby devices.

Option B:
Option B is correct because Bluetooth is widely recognised as the standard for short range wireless links among personal devices, matching the examples in the stem.

Option C:
Option C, Wi Fi, supports higher data rates and longer ranges in local area networks and is usually used for internet access rather than direct peripheral connectivity.

Option D:
Option D, NFC, stands for near field communication and is used for very short range interactions such as contactless payments, not general purpose audio or peripheral links.

Statements A, B, C and E are correct on gendered roles, policy impacts, clean cooking benefits and participation. Statement D is wrong because gender analysis is crucial in adaptation. Statement F is wrong as environmental stress can aggravate gender-based violence. Therefore A, B, C and E only is correct.

Option A:
Option A is incorrect because it includes D (false).

Option B:
Option B is correct because it includes A, B, C and E and excludes D and F.

Option C:
Option C is incorrect because it includes F (false) and omits A.

Option D:
Option D is incorrect because it includes F (false) and omits B.

After a researcher has identified and selected a research problem, the next logical step is to examine what has already been studied about that topic. Reviewing related literature helps in understanding existing theories, methods and findings relevant to the problem. It also assists in identifying gaps, refining the problem and avoiding unnecessary duplication. Therefore, in the usual research sequence, reviewing related literature follows the selection of the research problem.

Option A:
Defining the population is important for planning sampling, but it occurs after the researcher has clarified the problem and understood the context through the literature. Without a clear grasp of previous work, decisions about the population may be poorly informed. Hence, defining the population is not the immediate next step after selecting the problem.

Option B:
Constructing the tool for data collection requires clarity about what variables need to be measured and how they have been operationalised in previous studies. This information usually emerges from the review of literature. Designing instruments too early, before reviewing existing work, can lead to inappropriate or incomplete measures, so it is not the next step in the general sequence.

Option C:
Collecting the data is a field activity that should begin only after the problem has been refined, literature has been reviewed, hypotheses or questions have been formulated and tools and sampling plans have been prepared. Starting data collection immediately after selecting a problem would be premature and unstructured. Thus, data collection does not follow directly after problem selection in the standard sequence.

Option D:
Reviewing related literature allows the researcher to position the new study within the existing body of knowledge and to justify its significance. It influences all subsequent steps, including hypothesis formulation, tool construction and design selection. For this reason, review of related literature is correctly placed as the next major step after selecting the problem.

Statements A, B and D correctly describe institutional planning. Perspective plans articulate development goals, planning is guided by vision and mission, and participation of different stakeholders makes plans realistic and inclusive. Statements C, E and F are false because planning must include academic and student support dimensions, plans need periodic revision and evidence-based data are essential for meaningful planning.

Option A:
Option A is incorrect because it omits D, thereby not recognising that participatory processes strengthen ownership and plan quality.

Option B:
Option B is correct since it includes A, B and D and excludes C, E and F.

Option C:
Option C is incorrect because it omits A, so it fails to mention that perspective plans are medium to long-term development roadmaps.

Option D:
Option D is incorrect because it includes C (false), claiming planning ignores academic/student support dimensions.

In a star topology, each device on the LAN connects to a central hub or switch, so data travelling between two nodes always passes through this central point. This arrangement simplifies management and fault isolation and is therefore the standard design for many Ethernet-based ICT labs.

Option A:
This option accurately describes a star network, where each node has its own cable to a central device. If one link fails only that node is affected, while the hub or switch continues to serve the remaining nodes.

Option B:
This statement describes a ring topology, in which nodes form a closed loop and data circulates around the ring in one direction (or two). That pattern is different from the hub-and-spoke structure of a star.

Option C:
Having every node directly connected to all others with separate cables corresponds to a full mesh topology, which offers high redundancy but is usually too expensive and complex for typical ICT labs.

Option D:
A network where nodes are connected randomly with no clear pattern or central point does not represent a standard star topology and would be difficult to design, manage and secure.

Closed ended questions limit possible responses to a small set,such as yes/no or a specific fact. They are useful for checking recall or confirming understanding quickly. The stem refers to questions that need brief,definite answers,which is a clear description of closed ended questions.

Option A:
Open ended questions invite longer,more elaborate responses and multiple possible viewpoints,so they do not match the description of brief answers.

Option B:
Closed ended questions help in quick assessment and classroom management,making option B the correct completion.

Option C:
Divergent questions encourage diverse ideas and solutions,which is opposite to the narrow focus described.

Option D:
Reflective questions prompt learners to think deeply about experiences or concepts and usually require extended answers,rather than short yes/no responses.

Ethics committees are constituted to scrutinise research proposals for compliance with ethical standards. They assess risks, informed consent procedures and safeguards for participants or animals. The stem describes this function of reviewing moral acceptability, so “ethics” committees is the correct term.

Option A:
Finance committees examine budgets and expenditure plans rather than consent forms or risk–benefit analyses. They do not judge ethical aspects of research, so this option is not appropriate.

Option B:
Sports committees coordinate games and physical activities and have no authority over scientific research protocols. Therefore, this option cannot complete the statement.

Option C:
Discipline committees look into misconduct cases and violations of rules, but they are not specialised bodies for prospective ethical review of research projects. Hence, this option is incorrect.

Option D:
Ethics committees focus specifically on protecting participants’ rights, welfare and dignity in research. This matches the description in the stem and confirms that this option is correct.
