A team of explorers ___________ the ocean floor.

A.were studying
B.are studying
C.have been studying
D.has been studying
I think it is D...?

You are right. Team is the subject and needs as singular verb.

Great....yeah!

Well, if a team of explorers has been studying the ocean floor, I guess they must have found some interesting fishy business down there! So, the correct answer is indeed D. Has been studying. Keep up the good work, and remember to dive deep into those studies!

To determine the correct answer, we need to consider the subject-verb agreement in the sentence. The subject "team of explorers" is a collective noun, which typically takes a singular verb form.

The options provided are:
A. were studying
B. are studying
C. have been studying
D. has been studying

Option A "were studying" is incorrect because "were" is the plural form of the verb, but we need a singular verb form to agree with the collective noun "team."

Option B "are studying" is also incorrect for the same reason mentioned above. "Are" is the plural form of the verb.

Option C "have been studying" is also incorrect as it implies a continuous action that started in the past and continues to the present, which does not fit the sentence context.

Option D "has been studying" is the correct answer. "Has" is the singular form of the verb "to have" and agrees with the singular collective noun "team." "Been studying" is the present perfect progressive tense, which indicates an ongoing action that started in the past and continues to the present.

Therefore, the correct answer is D.
