When I got to the office, they had left.
Explanation:When we look at the sentence, we can identify that the action of leaving the office happened before the action of arriving at the office. Therefore, we need to use the past perfect tense to indicate that the action had already been completed before the simple past action.
Here is a detailed explanation of the solution:
- Past perfect tense is used to describe an action that happened before another past action or a specific time in the past.
- In this case, the action of leaving the office happened before the action of arriving at the office.
- The past perfect tense is formed by using the auxiliary verb "had" followed by the past participle of the main verb.
- In the sentence, the main verb is "leave" and its past participle is "left".
- Therefore, the correct form of the verb to use in this sentence is "had left".
- By using the past perfect tense, we indicate that the action of leaving the office had already been completed before the action of arriving at the office.
