The question tag is a grammatical structure used to turn a statement into a question. It consists of a short question appended to the end of a statement, typically to elicit confirmation or clarification from the listener. In English, the question tag usually consists of an auxiliary verb followed by a pronoun.

In the given sentence "Reema was not able to return the book on time," the subject is "Reema," and the auxiliary verb used is "was" (the past tense of "to be") in the negative form "was not." To form the question tag, we use the auxiliary verb "was" in its positive form "was she," and we add a question mark at the end to indicate that it's a question.
