UGC NET Questions (Paper – 1)

Achieving objectives reflects effectiveness; optimal use of time/resources reflects efficiency. The stem includes both, so it indicates high effectiveness and efficiency.

Option A:
Effectiveness and efficiency together mean goals are met and resources/time are used optimally, exactly as described.

Option B:
Authoritarianism is about control/obedience, not outcomes + resource optimisation.

Option C:
Conformity is adherence to norms, not necessarily improved outcomes or resource use.

Option D:
Rigidity is inflexibility and can reduce effectiveness/efficiency when learners need adaptation.

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.

Statements A, B and C are correct: A defines carbon footprint, B defines ecological footprint and C notes their use as sustainability indicators. Statement D is incorrect because, although related, the two concepts are not identical; carbon footprint focuses on emissions whereas ecological footprint covers broader resource and land-use aspects. Option D includes D and omits B, so it is not the correct answer. The correct combination must include A, B and C only.

Option A:
Option A is correct because it includes the three true statements and excludes D. It distinguishes between the narrower emissions-focused carbon footprint and the broader land-demand-focused ecological footprint, while acknowledging their use in assessment. This aligns with the conceptual treatment of the indicators.

Option B:
Option B is incorrect as it leaves out B, which is essential for explaining ecological footprint, and thereby gives an incomplete picture.

Option C:
Option C is incorrect since it includes D, which wrongly treats the two indicators as identical and interchangeable. This ignores important conceptual differences between them.

Option D:
Option D is incorrect because it accepts D while omitting B. It fails to provide the proper definition of ecological footprint and conflates the two measures, making the combination unacceptable.

Ecological overshoot occurs when humanity’s or a population’s demand on ecosystems exceeds what those ecosystems can regenerate in a given period. This leads to depletion of natural capital and accumulation of wastes. The stem clearly references footprint exceeding biocapacity,which is the defining condition of overshoot,so this is the correct term.

Option A:
Equilibrium would imply a balance between demand and regenerative capacity,which is the opposite of the situation described. Thus it cannot accurately fill the blank.

Option B:
Overshoot highlights that society is drawing down stocks of resources and filling waste sinks faster than they can recover. This unsustainable trajectory eventually forces either ecological or social adjustments. The explanation fits exactly with the question’s scenario.

Option C:
Neutrality suggests no net impact or balance, such as carbon neutrality, and does not convey the idea of exceeding capacity. Therefore it is not the proper term here.

Option D:
Substitution refers to replacing one resource or technology with another. While it may help address overshoot,it is not the name of the condition in which demand surpasses biocapacity.

Statements A, B and D are correct: affluent overconsumption drives environmental degradation, behaviour changes in high-income groups can ease pressure on resources and media influence preferences and impacts. Statement C is incorrect because sustainable consumption is especially relevant for high-consuming groups, not only low-income households. Therefore, the combination A, B and D only is correct.

Option A:
Option A is correct as it includes all the true statements and excludes C, which misplaces the main responsibility for unsustainable consumption. It aligns with the distributive focus of the unit.

Option B:
Option B is incomplete since it omits D, thereby ignoring the important role media and advertising play in shaping consumption choices and environmental outcomes.

Option C:
Option C is incorrect because, although B and D are true, it includes C which wrongly suggests sustainable consumption concerns only the poor in developing countries.

Option D:
Option D is incorrect as it groups A, C and D and treats C as correct, undermining the emphasis on high-consuming groups in sustainability debates.

Statements A, B, C, D and F are correct and capture resource waste, climate impacts, food security implications, behavioural drivers and policy responses. Statement E is false because food waste represents financial loss for households and businesses and adds costs for municipal waste management. Therefore, the combination that includes all true statements and excludes E is A, B, C, D and F only.

Option A:
Option A is correct as it reflects the full range of environmental, economic and social dimensions of food waste, while rejecting the claim that there are no economic implications.

Option B:
Option B is incorrect because it omits F, thereby ignoring policies and campaigns that are central to reducing waste in practice.

Option C:
Option C is incorrect since it includes E, which denies economic consequences, so it mixes true and false statements and cannot be the correct option.

Option D:
Option D is incorrect because it leaves out B, ignoring methane generation from landfilled food waste, which is a key greenhouse gas concern.

The ecological footprint measures how much biologically productive land and water area is needed to supply a population’s resources and absorb its wastes. High consumption of meat, energy-intensive goods and frequent air travel significantly increases this demand. Meat production requires large amounts of land, water and feed, while energy-intensive products and aviation burn substantial fossil fuels. Thus, a rapid rise in such consumption patterns increases the ecological footprint more than efficiency improvements or afforestation.

Option A:
Option A would generally reduce ecological footprint because mass public transport uses energy more efficiently per passenger than private cars. It lowers fuel consumption and associated land use for roads and parking.

Option B:
Option B is incorrect as afforestation and forest protection expand biocapacity rather than demand. They can help balance or even reduce the ecological deficit by increasing nature’s ability to regenerate resources and absorb carbon.

Option C:
Option C is incorrect because improving energy efficiency reduces the energy needed for the same level of output or comfort. This typically lowers resource use and emissions, thereby shrinking the ecological footprint if rebound effects are controlled.

Option D:
Option D is correct since increased meat consumption, energy-hungry lifestyles and air travel are well-known drivers of higher footprints in affluent societies. These behaviours raise per capita resource demand and waste generation beyond what local or global ecosystems can sustainably supply.
