Sentence Correction: Subject Verb Agreement - X of Y Subject

A team of interdisciplinary scientists are working on a top secret project.

You're right!

This answer choice corrects the original Subject Verb Agreement mistake, by changing the plural verb are to the singular verb is, to match the singular subject A team

[[snippet]]

Incorrect.

This answer choice is grammatically incorrect. The singular subject A team does not agree with the plural verb are.

[[snippet]]

Incorrect.

While this answer choice corrects the original Subject Verb Agreement mistake, it changes the meaning of the sentence by changing the singular noun a team to the plural teams.

Since there is an answer choice that corrects the original mistake without making any more changes, it is preferable to this answer choice.

Incorrect.

This answer choice is grammatically incorrect. The subject Teams is now plural, so the singular verb is does not agree with it. Note that when both the subject and the verb are underlined, you should check them both in every answer choice, not only the verb.

Incorrect.

While this answer choice corrects the original Subject Verb Agreement mistake and is grammatically correct, it is stylistically flawed - redundant - as it replaces the single word working with a two-word phrase doing work.
