Answer 2

Answer:

Explanation:

The thief _had escaped___ (escape) before the police came.​

Here we have to put the verb and this should be in correct tense. As the second verb  is past so, first verb will be past perfect tense.That's why it is written "had escaped".

What is past perfect tense?

The past perfect tense refers to a period of time prior to the present. It's used to show that one event occurred before the other in the past. It makes no difference which incident is mentioned first; the tense indicates which occurred first.

The final answer is " had escaped" .
