Sentence Correction: Subject Verb Agreement - X of Y Subject

A jury is a group of citizens that hear the testimony in legal disputes and determine what it believes is the truth.

Incorrect.

This answer choice is grammatically incorrect. The singular subject group does not agree with the plural verbs hear and determine.

Two Stop Signs help us identify this question as a Subject Verb Agreement question as well as identify this mistake:

- A pseudo-plural singular subject

- An X of Y subject

A group of citizens is an X of Y subject. In such cases, the verb should agree with X, namely, group.

Group is a confusing subject. It refers to more than one person, which might make us think of it as a plural subject, but it is, in fact, singular. Its plural form of groups.

Good!

This answer only partially corrects the original Subject Verb Agreement mistakes. It changes the plural verb hear to the singular form hears but leaves the plural verb determine unchanged.
