Answer 2

1) The baby (not/sleep) when Granpa (arrive)

In this sentence, we need to determine whether to use the Past Simple or Past Continuous tense for the verbs "sleep" and "arrive".

To describe an action that was happening at a specific point in the past, we use the Past Continuous tense. The Past Continuous tense is formed with the past tense of the verb "to be" (was/were) and the present participle (-ing form) of the main verb.

Therefore, the correct sentence would be: The baby was not sleeping when Granpa arrived.

Explanation: The Past Continuous tense is used to describe an ongoing action in the past. In this case, the baby was in the process of not sleeping when Granpa arrived. The Past Simple tense, on the other hand, is used to describe a completed action in the past. Since the baby's state of not sleeping was ongoing, we use the Past Continuous tense.
