Choose the past perfect or the past simple. 8. I opened the fridge to find someone (eat) all my chocolate.

{ "answer": "8. I opened the fridge to find that someone **had eaten** all my chocolate.

**Explanation:**
* 'Opened' is in the past simple. The eating of the chocolate happened *before* the action of opening the fridge. Therefore we use the past perfect tense ('had eaten')." }
