Question

Which best describes a rule for subject-verb agreement? Phrases or clauses should never separate subjects and verbs. Compound subjects joined by “and” are never plural. Singular subjects have singular verbs. Plural subjects can have singular or plural verbs.

Answer 1

What best describes a rule for subject-verb agreement is singular subjects have singular verbs.

In the subject-verb agreement, the subject and the verb should agree with each other in number that is singular or plural. Therefore,  the subject is plural then the verb form is plural and if the subject is singular then the verb form is singular.

For example

• The child is/are playing in the garden. (Subject, a child is singular hence, verb form will be singular.)
• Books is/are kept on the table. ( Subject, books is plural, hence, the verb will be plural.)

Answer 2

The answer is:

singular subjects have singular verbs.
