Question

He(go)___to London where he(not/be)___before. had go/wasn't had went/wasn't went/hadn't be went/hadn't been

Answer 1

He had go to London where he wasn’t before

Answer 2

He had gone to London where he had not been before.

In this sentence, the verb "go" is in the past participle form "gone" to indicate a completed action. The auxiliary verb "had" is used to show that the action of going to London occurred before another past event or time. The word "not" is used to indicate that he had not been to London previously.

The correct form is "had gone" because it is in the past perfect tense, which is used to indicate an action that happened before another past action or time. In this case, the action of going to London happened before the time being referred to in the sentence.

The other options are incorrect:

- "wasn't" is not the correct form of the verb "be" to use in this sentence. The past tense of "be" is "was" or "were," but it is not needed in this sentence.

- "had went" is incorrect because the past participle form of the verb "go" is "gone," not "went."

- "wasn't went" is incorrect because "wasn't" is not the correct form of the verb "be" to use in this sentence, and "went" is not the correct form of the verb "go" to use in this sentence.

- "hadn't be went" is incorrect because "be" is not the correct verb to use in this sentence. The correct form is "hadn't been," using the past participle form of "be."

- "hadn't been" is the correct form of the verb "be" to use in this sentence, but "went" is not the correct form of the verb "go" to use in this sentence. The correct form is "had gone."
