UGC NET Questions (Paper – 1)

Green buildings are designed to reduce resource use and environmental footprints throughout their life cycles. They incorporate strategies such as effective insulation, natural lighting, water-saving fixtures and sustainable materials. The goal is to provide comfortable, healthy indoor environments while using less energy, water and raw materials. Therefore, the feature emphasising efficient use of energy, water and materials with minimal environmental impact correctly reflects green building principles.

Option A:
Option A is correct because it summarises the integrated approach of sustainable building design. Such buildings often include renewable energy systems and rainwater harvesting, further lowering their ecological footprint.

Option B:
Option B is incorrect since exclusive reliance on air-conditioning and artificial lighting generally increases energy consumption. Green design encourages natural ventilation and daylighting wherever possible.

Option C:
Option C is incorrect because uninsulated concrete and glass buildings can lead to high heat gain or loss, making them energy inefficient. Green architecture promotes appropriate shading and insulation to maintain comfort with lower energy input.

Option D:
Option D is incorrect as ignoring local climate results in buildings poorly adapted to their environment. Climate-responsive design is a hallmark of sustainable architecture, reducing reliance on mechanical heating and cooling.

Statements A and B express the core idea of sustainable development, which is to balance economic growth with environmental protection and social equity while meeting present needs without compromising the ability of future generations. Statement C is incorrect because sustainable development does not reject technological innovation; instead, it promotes cleaner and more efficient technologies. Statement D is incorrect because sustainable development discourages over-exploitation of resources and promotes their prudent use. Therefore, the only correct combination of statements is A and B.

Option A:
Option A is correct because it includes statements A and B, both of which accurately define sustainable development as a balance among economic, environmental and social dimensions and emphasise intergenerational equity. Neither of these statements contains any exaggeration or contradiction with accepted definitions used in policy documents and UGC NET syllabus. Since statements C and D are false, excluding them makes this combination fully correct.

Option B:
Option B is incorrect because it adds statement C to the otherwise correct pair A and B. Statement C wrongly suggests that sustainable development rejects technological innovation, whereas in reality sustainable development encourages innovations such as renewable energy, cleaner production and eco-friendly technologies. Including an incorrect statement makes the whole combination wrong.

Option C:
Option C is incorrect because it combines B, C and D. Although statement B is correct, statements C and D are both incorrect. Statement C misrepresents the role of technology, and statement D promotes over-exploitation of resources, which is against the principle of sustainability. Due to the presence of these false statements, the combination cannot be correct.

Option D:
Option D is incorrect because it includes all four statements A, B, C and D. While A and B are true, C and D contradict the very idea of sustainable development by rejecting technological solutions and encouraging overuse of resources. A correct combination must exclude false statements, so selecting all four statements leads to an incorrect answer.

Statements A, C, D and E together describe comprehensive green campus initiatives. A is correct because energy conservation, waste management and biodiversity measures are typical green practices. C is correct as curricular integration strengthens environmental awareness and values. D is correct because green audits provide measurable data to guide improvement. E is correct since student-led eco-groups often organise campaigns and projects. B is false because sustainability policies are relevant obligations for HEIs, and F is false because green initiatives must be continuous rather than limited to single events.

Option A:
Option A is incorrect because it omits E and therefore fails to recognise the role of student initiatives in sustaining campus environmental projects.

Option B:
Option B is correct as it includes all the true statements about policies, curriculum, audits and student participation, while excluding B and F, which wrongly treat sustainability as irrelevant or purely ceremonial.

Option C:
Option C is incorrect because it includes B, which claims sustainability is irrelevant, and still omits A, thereby distorting the description of green campus work.

Option D:
Option D is incorrect because it includes B and omits C, so it accepts a false dismissal of environmental relevance and ignores the curricular dimension of sustainability education.

Intergenerational equity holds that present development should not compromise the ability of future generations to access resources and enjoy a healthy environment.

Option A:
Incorrect, because prioritising present economic growth at any cost can deplete resources and degrade ecosystems for future people.

Option B:
Correct, as it directly expresses fairness between current and future generations in terms of resources and environmental quality.

Option C:
Incorrect, since military strength is not the central concern of intergenerational equity.

Option D:
Incorrect, because exhausting non-renewable resources now would severely restrict future generations, violating this principle.

Sustainable agriculture aims to meet present food needs without compromising the ability of future generations to meet their own needs from the same resource base. It emphasises soil conservation,efficient water use and reduced chemical dependence. The stem highlights maintaining fertility,conserving water and protecting the environment for long term productivity,which clearly fits sustainable agriculture. Thus sustainable is the correct option.

Option A:
Subsistence agriculture focuses on producing enough food mainly for the farmer’s family with little surplus. It may or may not follow environmentally sound practices and is not defined by long term resource stewardship,so it does not fully match the description.

Option B:
Commercial agriculture is oriented toward market production and profit, often using high levels of inputs. Without specific safeguards,it can cause soil and water degradation. Therefore it does not inherently reflect the sustainability criteria mentioned in the question.

Option C:
Sustainable agriculture integrates ecological principles such as crop rotation,integrated pest management and agroforestry. These practices maintain productivity while minimising negative environmental impacts. This directly corresponds to the goals listed in the stem.

Option D:
Shifting agriculture involves clearing forest patches, cultivating them briefly and then moving on. It can be sustainable at low population densities but is not primarily defined by deliberate conservation measures,so it is not the best term here.

Sustainable development is most widely defined as meeting the needs of the present without compromising the ability of future generations to meet their own needs. This definition captures both intergenerational equity and the idea of long-term environmental stewardship. It recognises that development and environment are interlinked and that economic progress should respect ecological limits. Therefore, option A reflects the accepted Brundtland Commission definition and is conceptually complete.

Option A:
Option A captures the balance between development and environmental protection by explicitly mentioning present and future generations. It includes the idea that resources should be used in a way that does not undermine long-term human welfare. It is aligned with international understanding and UGC NET syllabus discussions on sustainable development.

Option B:
Option B is incorrect because it focuses only on economic growth, ignoring environmental and social dimensions. Sustainable development emphasises that growth must be ecologically sustainable and socially equitable. Growth that damages ecosystems and increases inequality cannot be called sustainable.

Option C:
Option C is incorrect because it suggests stopping all development, which is neither practical nor desirable. Sustainable development aims at reconciling development with environmental conservation, not rejecting development. A total halt in development would also harm human welfare and poverty alleviation.

Option D:
Option D is incomplete as it refers only to the poor and only to basic needs. Sustainable development concerns the needs of all people and emphasises both present and future generations. It also includes broader issues such as quality of life, resource use and environmental protection.

The definition given in the question is the classic Brundtland Commission definition of sustainable development. It explicitly links present needs with the rights of future generations. The idea stresses intergenerational equity and long term resource security. Therefore the only concept that fully captures this definition is sustainable development.

Option A:
Sustainable development integrates economic efficiency,social equity and environmental protection. It ensures that development does not degrade the resource base needed by future generations. Because it balances present benefits with future needs,it correctly matches the definition in the stem.

Option B:
Economic growth refers mainly to an increase in the value of goods and services produced in an economy. It does not necessarily take environmental limits or equity into account. Rapid economic growth can actually undermine sustainability if it depletes resources and increases pollution.

Option C:
Human development focuses on expanding people’s capabilities in areas such as health,education and income. Although it is concerned with improving quality of life,it does not inherently include the intergenerational environmental focus mentioned in the definition. Hence it is related but not an exact fit for the idea in the stem.

Option D:
Industrialisation describes the shift to factory based and mechanised production. Historically it has often led to increased pollution and resource extraction. By itself,it does not guarantee protection of future generations’ needs,so it does not match the given definition.

Sustainable consumption aims to reduce the environmental impact of goods and services over their life cycle. Choosing durable products and repairing them extends their useful life and lowers the demand for new production. This reduces resource extraction, energy use and waste generation associated with manufacturing and disposal. Therefore, the practice of using and repairing long-lasting items is a clear example of sustainable consumption.

Option A:
Option A is correct because it embodies the principles of reduce and reuse. Households that maintain and repair products generate less waste, save money and lower their ecological footprint, aligning daily choices with sustainability goals.

Option B:
Option B is incorrect since leaving lights and fans on wastes electricity and increases emissions from power generation. It contradicts the idea of conserving energy at home.

Option C:
Option C is incorrect because throwing away edible food increases solid waste and squanders the resources used to produce and transport that food. Sustainable consumption would encourage better planning, storage or sharing to avoid food waste.

Option D:
Option D is incorrect as buying heavily packaged products for appearance leads to unnecessary material use and waste. Sustainable consumers typically prefer minimal or recyclable packaging.
