UGC NET Questions (Paper – 1)

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.

Statements A, B, C, D and E are all correct and describe multiple links between nutrition, food safety and environment. Chemical contamination and poor water, sanitation and hygiene affect health, while diversity, safety and climate-related yield changes shape nutritional outcomes and risks. Regulations and monitoring are key tools in preventing food-borne illness. F is wrong because household storage and preparation practices clearly interact with environmental health conditions, influencing contamination and disease. Thus, the correct combination includes A through E only.

Option A:
Option A is correct since it recognises the broad set of true statements and excludes only F, which denies the role of household practices. It reflects an integrated view of nutrition that considers environment, climate, regulation and household behaviour.

Option B:
Option B is incorrect because it omits E, ignoring how water quality and sanitation impact nutrition, especially in children. Without E, the answer set fails to incorporate the WASH–nutrition connection.

Option C:
Option C is incorrect as it includes F and omits A. Accepting F contradicts public health guidance on food hygiene, and dropping A overlooks the risks posed by pesticide and heavy metal contamination.

Option D:
Option D is incorrect since it leaves out B and includes only A, C, D and E. Although the four included statements are true, excluding B means the answer does not fully acknowledge the role of dietary diversity and access in nutrition.

Statements A, B and D are correct and highlight the links between women’s education, fertility decline and better environmental management when women participate in decision-making. Statement C is incorrect because women’s empowerment is widely recognised as central to sustainable development and environmental governance. Hence, the combination that includes A, B and D and excludes C is the correct answer.

Option A:
Option A is incorrect because, although A and B are true, it omits D which correctly points to the positive role of women in community resource management. Without D, the view of women’s contribution to sustainability is incomplete.

Option B:
Option B is incorrect as it selects only B and D and leaves out A. While B and D are correct, A is also true in emphasising environment-friendly practices at the household level. Excluding A means the full picture of empowerment effects is not presented.

Option C:
Option C is correct because it groups all three true statements and rejects the false claim in C. It reflects the multi-layered importance of women’s empowerment for demographic, social and environmental outcomes.

Option D:
Option D is incorrect since it includes C, which wrongly denies the connection between empowerment and sustainable development. Mixing a false statement with true ones makes the option invalid.

Energy conservation refers to reducing energy use by avoiding waste and improving practices without necessarily changing technology. Turning off unused lights and fans directly cuts electricity consumption and is a classic conservation behaviour. The stem describes exactly this type of action,so energy conservation is the correct term. Therefore Option C fits best.

Option A:
Generation is producing electricity at power plants; it is not the household action described.

Option B:
Transmission is delivering electricity through the grid; it is not about switching off appliances at home.

Option C:
Energy conservation reduces energy use through behavioral or operational changes like switching off devices when not needed,matching the stem.

Option D:
Waste collection relates to solid waste management,not electricity saving behavior.
