Answer 1

Our school library ___ ten thousand books.

Answer:

Our school library has ten thousand books.

• In ''subject-verb'' agreement, subjects and verbs must agree with one another.

• If the subject is singular then the helping verb is also singular whereas if the subject is plural then the helping verb is also plural.

• In the given sentence, the subject 'library' is singular so the auxiliary verb must be singular too. so we should use the singular helping verb "has" instead of "have"

• 'was' is used with simple past tense whereas 'is' is used with the simple present tense.
