Paper 1 · People, Development and Environment
UGC NET December 2021 June 2022 (09.07.2022) Shift-I
Given below are two statements, one labelled Assertion (A) and the other Reason (R). Choose the correct answer.
Assertion (A): Green hydrogen production will be critical for the world community to achieve carbon neutrality by the year 2050.
Reason (R): The energy content of hydrogen gas is much higher than that of coal.
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) ✓ Correct
C(A) is true but (R) is false
D(A) is false but (R) is true
Correct answer: (B) Both (A) and (R) are true but (R) is NOT the correct explanation of (A) — Both statements are true, but the reason is not the correct explanation, so option B is correct.
Explanation
★Both statements are true, but the reason is not the correct explanation, so option B is correct.
★Green hydrogen is made by splitting water using electricity from renewable sources.
★Because it produces no carbon emissions, it is critical for reaching carbon neutrality by 2050.
★So the assertion about its importance for carbon neutrality is true.
★Hydrogen does carry far more energy per unit mass than coal, so the reason is also true.
★However, hydrogen matters for carbon neutrality because it is clean, not because it is energy dense.
★So the high energy content is a true fact but not the reason green hydrogen aids carbon neutrality.
