Choose the past perfect or the past simple. 1. We had already eaten when John (come) home.

{ "answer": "1. We had already eaten when John **came** home.

**Explanation:**
* The first part of the sentence 'We had already eaten' is in the past perfect tense, indicating an action completed before another action in the past.
* Therefore, the second action 'John (come) home' needs to be in the past simple tense, so 'came' is the correct answer." }
