Question

You, he and I.. ..good friends (is /are)

Answer 1

are..............................

Answer 2

You, he, and I are good friends.

• The given blank is to be filled with the verb ''are''.

Subject and verb agreement:

• In ''subject-verb'' agreement, subjects and verbs must agree with one another.
• If the subject is singular then the verb is also singular whereas if the subject is plural then the verb is also plural.
• If the noun is singular then add ''s'' to the verb. If the noun is plural then no need to add ''s'' to the verb.

There are three persons in the subject of the sentence. Hence we use the plural verb ''are''.
