(A) are thought to have first extracted

(B) were thought first to extract

(C) were thought at first to extract

(D) are thought of as first extracting

(E) were thought to first extract


MANHATTAN REVIEW EXPLANATION:



Do you use the past or present tense here? It is thought now that hunters extracted oil. Therefore you must use the present tense to describe that thinking. Eliminate B, C and E. Choice D is incorrect because it places the things the hunters did in the present tense, whereas what they did is a past action. Choice A is the correct answer.

Present tense will be used since we are thinking of an action "NOW" which happened in the past
A suits best
