Question

What is the basic principle in subject-verb agreement?

A. The subject of the sentence is always singular and the verb agrees with it.
B. Singular subjects need singular verbs while plural subjects need plural verbs.
C. Singular subjects need plural verbs while plural subjects need singular verbs.
D. The subject usually refers to something earlier in the text, most likely the verb.

Answer 1

Answer:
B. Singular subjects need singular verbs while plural subjects need plural verbs.

The agreement consists in that the number of the verb and the number of the subject need to be the same: if the subject is singular the verb has to be singular, and if the subjetc is plural the verb has to be plural.

Verb-subject disagreement is a grammatical error.
