Consider the following statements:Statement I: Of the two major ethanol producers in the world,i. e., Brazil and the United States of America, the former produces more ethanol than the latter.Statement II: Unlike in the United States of America where corn is the principal feedstock for ethanol production, sugarcane is the principal feedstock for ethanol production in Brazil.Which one of the following is correct in respect of the above statements?

A Both Statement I and Statement II are correct and Statement II explains Statement I
B Both Statement I and Statement II are correct but Statement II does not explain Statement I
C Statement I is correct but Statement II is not correct
D Statement I is not correct but Statement II is correct

Correct answer: (d) Statement I is not correct but Statement II is correct

Explanation

  1. A

    Both Statement I and Statement II are correct and Statement II explains Statement I

    Both correct and II explains I. I is the false ranking/claim on the two major ethanol producers.

  2. B

    Both Statement I and Statement II are correct but Statement II does not explain Statement I

    Both correct without explanation. I still fails.

  3. C

    Statement I is correct but Statement II is not correct

    I correct, II not. I is not keyed.

  4. D

    Statement I is not correct but Statement II is correct

    I is not correct, II is correct. The ethanol-producer ranking in I fails; II holds on this paper.

Summary. Official Set A key is (d). Statement I on the two major ethanol producers is not correct as written. Statement II is scored as correct. So I not, II yes — not the ‘both and II explains I’ trap.
