Directions: In the following items a pair of sentences (S1, S2) is given. Select the most appropriate and relevant co-relationship of the second sentence to the first from among the options (a), (b), (c) and (d), and mark your response on the Answer Sheet accordingly.
S1: A four-stroke engine is more efficient than a two-stroke engine.
S2: The two-stroke engine has been phased out to protect the environment.
The second sentence:
- Acorrelates to the first
- Bcontradicts the first
- Ccontrasts with the first
- Dconfirms the first
Explanation
S2 (two-stroke engines phased out for environmental reasons) is a related fact about two-stroke engines that neither confirms nor denies S1's efficiency comparison. The two statements correlate — they concern the same subject from complementary angles. "Correlates to the first" (A) is therefore the best description; "contrasts" and "contradicts" are too strong, and "confirms" is inaccurate.
