Paper 1 · People, Development and Environment
Assertion (A): Cloudy nights are warmer compared to clear nights (without clouds) during winters. Reason (R): Clouds permit cold waves from the sky to reach the earth. Choose the correct answer.
ABoth (A) and (R) are true and (R) is the correct explanation of (A)
BBoth (A) and (R) are true but (R) is not the correct explanation of (A)
C(A) is true, but (R) is false ✓ Correct
D(A) is false, but (R) is true
Correct answer: (C) (A) is true, but (R) is false — (A) is true but (R) is false, so that is the answer.
Explanation
★(A) is true but (R) is false, so that is the answer.
★Cloudy winter nights are indeed warmer than clear nights, so the assertion is true.
★But the reason is wrong: clouds do not let cold waves reach the earth.
★In fact clouds trap the earth's outgoing heat and keep the surface warm.
★So the reason misstates how clouds work.
★So (A) is true but (R) is false.
