Select the best suitable option for the sentence: “Where are the book we had bought together.”

Correct answer: Where are the books we had bought together?. “Books” is plural, so “are” is needed, and the sentence is a question that ends with a question mark.

Background: The subject and verb must agree in number.

• Where were the book we bought together: “Were … book” does not agree in number and tense.
• Where are books we had bought together: Missing “the” makes it incorrect.
• Where was the books we had bought together: “Was … books” does not agree in number.

Did you know? The past perfect “had bought” shows that the buying happened earlier.

Memory trick: Plural books → are.
