In the question below choose the word(s) or phrase(s) which best fills(s) the gap(s):
We must observe that most of the support by other states _____ only marginal returns
Answer Details
The correct option to fill the blank is "have yielded".
The subject of the sentence is "most of the support by other states," which is plural, so we need a plural verb. Additionally, the past participle form "yielded" is required to match with the auxiliary verb "have", indicating the action has been completed in the past.
Option A, "have yielded," is the correct form of the present perfect tense, indicating that the support provided by other states has resulted in marginal returns up until the present time. Option B, "yield," is incorrect because it is in the present tense, not the present perfect tense. Option C, "has yielded," is incorrect because it is singular, not plural. Option D, "have yield," is incorrect because it uses the wrong form of the verb.
