Paper 1 · People, Development and Environment
Consider the following statements comparing Coal Bed Methane and shale gas. Statement 1: Coal bed methane is the pure methane gas extracted from coal seams, while shale gas is a mixture of propane and butane only, extracted from fine-grained sedimentary rocks. Statement 2: In India, abundant coal bed methane sources exist but so far no shale gas has been found. Which of the statements is/are correct?
- Coal bed methane is pure methane from coal seams, while shale gas is a mixture of propane and butane only
- In India abundant coal bed methane sources exist but so far no shale gas has been found
ABoth 1 and 2 are correct
B1 is correct while 2 is incorrect
C1 is incorrect while 2 is correct
DNeither 1 nor 2 is correct ✓ Correct
Correct answer: (D) Neither 1 nor 2 is correct — Neither statement is correct, so that is the answer.
Explanation
★Neither statement is correct, so that is the answer.
★Statement one is wrong, because shale gas is not merely a mixture of propane and butane.
★Statement two is wrong, because India does have shale gas potential, not none.
★So both statements misdescribe the two gases.
★Since neither holds, the answer is neither.
★So the answer is neither 1 nor 2 is correct.
