Question

He(not/play)___tennis before that day. didn't play hadn't played hadn't play hasn't played

Answer 1

He didn’t play tennis before that day

Answer 2

He hadn't played tennis before that day.

In this sentence, we are talking about the past and using the past perfect tense. The subject "he" is the person we are referring to. The negation "not" is used to show that he did not play tennis.

The verb "play" is in the base form because we are using the auxiliary verb "had" to form the past perfect tense. The past perfect tense is used to describe an action that was completed before another past action. In this case, the action of not playing tennis occurred before that specific day.

To summarize, the correct form of the negative past perfect tense of the verb "play" in this sentence is "hadn't played."
