5. It …(start) to rain, and I …(remember) that I …(not close) my vindow.
6. I …(already tell) Bob I couldn’t go to the theatre, but he …(buy) the tickets.

1. Bill didn't tell anybody how he got into the house.
Explanation: The action of not telling happened before the action of getting into the house, so we use the Past Perfect form "had gotten" for the first action and the simple past form "did not tell" for the second action.

2. Emma went to France last week. Before that, she had never been outside Latvia.
Explanation: The action of going to France happened after the action of never being outside Latvia, so we use the Past Perfect form "had never been" for the second action and the simple past form "went" for the first action.

3. When their mother got home, the children had eaten all the sweets.
Explanation: The action of eating the sweets happened before the action of the mother getting home, so we use the Past Perfect form "had eaten" for the first action and the simple past form "got" for the second action.

4. Yesterday I met a man who had been at school with my grandmother.
Explanation: The action of being at school with the grandmother happened before the action of meeting the man, so we use the Past Perfect form "had been" for the first action and the simple past form "met" for the second action.

5. It started to rain, and I remembered that I hadn't closed my window.
Explanation: The action of not closing the window happened before the action of remembering, so we use the Past Perfect form "hadn't closed" for the first action and the simple past form "remembered" for the second action.

6. I had already told Bob I couldn't go to the theatre, but he bought the tickets.
Explanation: The action of telling Bob happened before the action of Bob buying the tickets, so we use the Past Perfect form "had already told" for the first action and the simple past form "bought" for the second action.
