UGC NET Questions (Paper – 1)

Check dams help communities adjust to increased rainfall variability and drought risk by improving local water availability. Such measures reduce vulnerability to the impacts of climate change. The stem explicitly labels the action as an adaptation measure,so the missing word is “climate.” Therefore “climate change adaptation” is correctly completed by Option B.

Option A:
Mitigation refers to actions that reduce greenhouse gas emissions or enhance sinks. Check dams primarily address impacts like water scarcity rather than directly lowering emissions,so Option A is not accurate here.

Option B:
Climate adaptation measures strengthen resilience to climate impacts rather than addressing their root causes. Recharging groundwater in drought-prone regions is a clear example of this,matching the question.

Option C:
Pollution control relates to managing contaminants and is not the main role of check dams in the described context. Therefore Option C does not fit the stem.

Option D:
Economic measures may accompany adaptation,but the defining feature of the action is its link to climate related drought risk,not simply economic policy,so Option D is unsuitable.

Statement B is the only wrong statement because effective environmental awareness today uses a mix of media, including digital and social platforms, rather than depending solely on printed posters. Statements A, C and D are correct as they highlight community-level folk media, experiential learning through eco-clubs and the role of mass media campaigns in shaping attitudes. Since only B misrepresents good practice in awareness-building, the correct choice is the combination that isolates B alone as wrong.

Option A:
Option A is incorrect because it treats both A and B as wrong, whereas statement A is actually correct. Community-level tools like street plays and rallies are widely used to communicate environmental messages in an accessible way. Including a correct statement among wrong ones makes this option logically inconsistent with the question.

Option B:
Option B is correct because it identifies B only as the wrong statement and leaves A, C and D recognised as valid. It acknowledges that limiting programmes to printed posters and excluding digital and social media would be a serious weakness in modern awareness strategies.Thus, this option precisely matches the requirement to select the wrong statement or statements.

Option C:
Option C is incorrect because it considers B and C as wrong. Statement C is in fact correct since eco-clubs and hands-on activities have been repeatedly emphasised in environmental education policies as important for student learning. Misclassifying it as wrong leads to an incorrect combination.

Option D:
Option D is incorrect because it treats B, C and D as wrong. While B is wrong, C and D are correct: eco-clubs support behaviour change and mass media campaigns are essential for reaching wide audiences. Grouping correct statements with the wrong one cannot satisfy the condition of the question.

A gendered perspective in environmental studies emphasises that environmental policies and impacts are experienced differently by women and men due to socially constructed roles and power relations. It calls for analysing resource access, decision making and vulnerability through a gender lens. The stem describes exactly this differentiated approach,so gendered is the correct term.

Option A:
An ecocentric perspective places intrinsic value on ecosystems and non human nature, often downplaying human social distinctions. While important,it does not focus on differences between women and men as stated in the question.

Option B:
A gendered perspective helps reveal how women may bear disproportionate burdens of environmental degradation, such as walking longer distances for water or fuelwood. It also highlights their knowledge and contributions to resource management. This reasoning aligns closely with the stem.

Option C:
A technocratic approach emphasises technical expertise and engineering solutions, sometimes neglecting social and gender dimensions. It is not specifically concerned with unequal roles or vulnerabilities by gender.

Option D:
Neo classical refers to a school of economic thought that assumes rational individuals and competitive markets. Although it can be applied to environmental issues, it does not inherently address gendered differences.

In many developing regions, poor households rely directly on common forests, grazing lands and water bodies for fuel, fodder and livelihoods. When these resources are degraded through overuse or external pressures, the poor lose crucial support systems. This can trap them in a vicious circle where poverty drives resource overuse, and degradation further entrenches poverty. Therefore, the statement linking heavy dependence with vulnerability to environmental degradation accurately describes the poverty–environment nexus.

Option A:
Option A is correct because it recognises the two-way relationship: poverty can force people to exploit resources unsustainably, and the resulting degradation can push them deeper into deprivation. This understanding underlies many community-based and sustainable livelihood programmes.

Option B:
Option B is incorrect since poor households do use natural resources extensively, often with limited alternatives. Ignoring their role misrepresents both their dependence and their potential contribution to conservation when given secure rights.

Option C:
Option C is incorrect because environmental damage is not caused only by rich households. While high consumption by the wealthy has large footprints, the survival needs of the poor also shape land use and resource conditions.

Option D:
Option D is incorrect as numerous studies show that poverty and environment are closely linked in developing contexts. Policies often try to address both together through integrated rural development and natural resource management.

Biomagnification describes how substances that are not readily metabolised, such as DDT or methylmercury, become more concentrated as they move up food chains. Predators at higher trophic levels accumulate contaminants from many prey organisms,leading to high internal concentrations. The stem referencing increases at successive trophic levels corresponds directly to biomagnification.

Option A:
Bioaccumulation focuses on the build up of a substance in a single organism over time,not on changes across trophic levels. While related,it does not capture the chain wide amplification described in the question.

Option B:
Biomagnification shows why top predators, including humans, can experience toxic effects even when environmental concentrations are low. Because the stem emphasises increases from level to level in the food chain,this process is the appropriate answer.

Option C:
Biotransformation refers to the chemical modification of substances by organisms,often through metabolic processes. It can sometimes reduce toxicity and does not necessarily result in increased concentrations. Therefore it is not the right option.

Option D:
Biofertilisation involves using microorganisms or organic materials to enhance soil fertility. It has nothing to do with pollutants increasing through food chains,so it cannot fit the blank.

The polluter pays principle is grounded in the idea that environmental costs should be internalised into production and consumption decisions. When those who generate pollution bear the financial burden of control and remediation, they have stronger incentives to reduce emissions and adopt cleaner technologies. This principle also promotes fairness by avoiding the transfer of private pollution costs onto the public at large.

Option A:
Option A is incorrect because making governments pay regardless of responsibility would effectively socialise the costs of private pollution and weaken incentives for prevention.

Option B:
Option B is correct as it states that those who cause pollution should pay for its control and damages, aligning with many environmental laws and economic instruments.

Option C:
Option C is incorrect since exempting polluters from responsibility goes against both economic efficiency and environmental justice; it would encourage careless practices.

Option D:
Option D is incorrect because both producers and consumers can be polluters, and the principle applies to whoever causes the environmental harm, not to a single group.

COP27 concluded with an agreement to establish new funding arrangements, including a dedicated loss-and-damage fund. This was a long-standing demand of vulnerable countries facing irreversible impacts like sea-level rise, storms and droughts. While many operational details are still being negotiated, the decision was hailed as historic for recognising the need for support beyond adaptation. (Press Information Bureau)

Option A:
This option correctly captures the core outcome relating to loss and damage and explains why it is important for climate justice.

Option B:
This option is incorrect because climate finance obligations were not cancelled; in fact, calls for scaled-up finance were reiterated.

Option C:
The Paris Agreement remains the main framework; COP27 decisions operate under it and address mitigation, adaptation and finance together.

Option D:
COP27 did not dismiss adaptation; rather, it emphasised both adaptation and loss and damage alongside mitigation.

Carrying capacity is rooted in ecology and refers to the maximum pressure ecosystems can bear without losing their functions. Using it in development planning means respecting ecological limits such as regeneration rates and waste assimilation capacity. The stem asks what type of limits must be respected,which are ecological limits. Therefore Option B is correct.

Option A:
Political limits are constraints arising from power relations and governance structures. They matter,but they are not the core of the carrying capacity concept.

Option B:
Ecological limits are set by how much extraction and pollution ecosystems can tolerate. Ignoring them leads to degradation and loss of services,so they are central to sustainable development thinking. This matches the question.

Option C:
Linguistic limits relate to language diversity and communication,which are important culturally but not relevant to carrying capacity as defined here.

Option D:
Cultural limits concern social norms and values and again are not the primary focus of the ecological carrying capacity framework,so Option D does not fit.

The Paris Agreement articulates a long-term global temperature goal to guide collective climate action. Parties agreed to hold the increase in global average temperature to well below 2°C above pre-industrial levels and to pursue efforts to limit the increase to 1.5°C. This goal reflects scientific assessments of thresholds beyond which climate impacts become increasingly dangerous. Hence, the statement in option A correctly summarises the central temperature goal of the agreement.

Option A:
Option A is correct because it captures both parts of the goal: the “well below 2°C” limit and the aspirational 1.5°C target. It aligns with the language negotiated and adopted by the parties.

Option B:
Option B is incorrect since the agreement cannot guarantee the absence of heat waves; it can only influence their likelihood by reducing emissions. Extreme events will still occur in a warming climate.

Option C:
Option C is incorrect because setting zero emissions by 2020 was neither realistic nor a stated objective. The agreement envisions a longer-term transition towards net-zero in the second half of the century.

Option D:
Option D is incorrect since the Paris framework expects contributions from all countries, though differentiated by national circumstances. It does not allow some countries to increase emissions indefinitely without responsibility.

Statements A, B, C, D and F are correct: solid fuels and poor ventilation raise indoor pollutants; exposure increases respiratory risks especially for women/children; cleaner fuels/improved stoves reduce exposure; and additional sources include materials, tobacco and chemicals. Statement E is false because exposure is strongly shaped by time spent indoors and gendered household roles. Hence, the correct combination is A, B, C, D and F only.

Option A:
Option A is correct because it includes all true statements and excludes only E, which wrongly denies the importance of time use and gender roles in exposure.

Option B:
Option B is incorrect because it omits F, thereby ignoring important indoor sources like building materials, tobacco smoke and household chemicals.

Option C:
Option C is incorrect since it includes E (false) and also omits A, missing the key role of solid fuels in indoor smoke generation.

Option D:
Option D is incorrect because it omits B, underplaying the critical role of ventilation in determining indoor concentrations.

Pull factors are attractive conditions at the destination that draw migrants. In rural–urban migration, expectations of higher wages, regular salaried jobs and better services in cities act as powerful pulls. People compare these perceived benefits with conditions in their villages and decide to move if they expect an improvement in their lives. Hence, better jobs and higher wages illustrate a typical pull factor.

Option A:
Option A is a push factor because drought and crop failure drive people away from origin areas rather than attract them to a specific destination.

Option B:
Option B is also a push factor, as people flee violence for safety, but it does not itself describe the attractions of towns.

Option C:
Option C is correct since higher wages and employment opportunities in urban centres draw people and fit the classic definition of pull factors.

Option D:
Option D again describes a push factor linked to environmental degradation in the village, not an attraction in the city.

In disaster studies,a natural hazard is a potentially damaging physical phenomenon such as an earthquake, flood or cyclone. It becomes a disaster only when it affects vulnerable people and assets. The stem clearly refers to the event before it interacts with society,so the correct term is hazard.

Option A:
A disaster is the serious disruption that occurs when a hazard actually impacts a vulnerable community and overwhelms its capacity to cope. Before this interaction happens, the event is classified as a hazard. Therefore disaster is not the right word in the blank.

Option B:
Hazard denotes the probability of occurrence of a potentially damaging physical event at a specific location. It is one of the components of disaster risk. Because the question emphasises the pre impact stage, hazard is the correct concept.

Option C:
Mitigation refers to measures taken in advance to reduce the potential impact of hazards by lowering vulnerability or modifying the hazard. It is a response strategy, not the physical event itself. Hence it does not fit the stem.

Option D:
Relief concerns immediate assistance after a disaster, including food, medical care and shelter. It occurs after the hazard has caused damage and is therefore not the term required in the question.

Statements A, B and D accurately outline key aspects of curriculum development. Boards of Studies do initiate and recommend syllabi, stakeholder feedback is expected to inform revision, and outcome-based frameworks articulate learning outcomes that guide teaching and assessment. Statements C, E and F are wrong because curricula must be periodically updated, teacher consultation is essential and alignment with national and professional expectations is important.

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

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

Option C:
Option C is incorrect because it includes C (false) and thus mixes correct and incorrect statements.

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

PM SuryaGhar is designed to install rooftop solar on about one crore households with central support. Beneficiary families can get up to 300 units of free electricity each month, which reduces their expenditure and dependence on fossil-fuel-based grid power. The scheme also turns citizens into producers of clean energy, promoting decentralisation and community participation in the energy transition. This aligns well with equity and sustainability goals.

Option A:
This option is incorrect because diesel generators are polluting and not the focus of the scheme.

Option B:
This option correctly summarises how rooftop solar under PM SuryaGhar provides financial relief to households while contributing to climate mitigation.

Option C:
Encouraging higher electricity use without considering the source would increase emissions; the scheme instead rewards clean generation.

Option D:
Captive coal plants run counter to the scheme’s emphasis on solar energy and decentralised renewables.

The tragedy of the commons describes how unregulated access to a shared resource can lead to over exploitation, even when it is against everyone’s long term interest. The classic example is herders grazing more animals on a common pasture until it is degraded. Since the resource is common to all, the phenomenon is called the tragedy of the commons. Therefore commons is the correct completion.

Option A:
The market refers to systems of voluntary exchange and prices. While market failures can contribute to resource overuse, the specific phrase coined by Garrett Hardin concerns common property resources,not markets in general.

Option B:
Commons are resources accessible to all or many members of a community, such as grazing lands, fisheries or groundwater. When no effective governance exists, individuals may overuse them,creating the tragedy described in the question. This logic matches the stem exactly.

Option C:
The state denotes governmental institutions and public authority. Although state management can sometimes prevent tragedies of the commons, the concept itself is not called the tragedy of the state.

Option D:
The firm is a business organisation whose internal decisions about resource use are typically hierarchical. Overuse of shared resources occurs between firms or individuals using commons,not within a single firm,so this term is inappropriate.
