10. The boss invited me to lunch, but I had to refuse the invitation (past perfect/ to eat sandwich)

Here is my answer:

10. The boss invited me to lunch, but I had to refuse the invitation because I had eaten a sandwich.

The past perfect tense is used to show that an action in the past happened before another action in the past. In this sentence, the action of eating a sandwich happened before the action of refusing the invitation. The past perfect is formed with the auxiliary verb had and the past participle of the main verb. The past participle of eat is eaten.
