Answer 1

We went to the theatre last evening.

Answer 2

Hey there!

The given sentence is We ____ (go) to the theatre last evening.

The answer would be:

We went to the theatre last evening.

We will use went as a correct form of verb here because the sentence is stated in the past tense. As 'last night' is mentioned in the sentence itself so it is the past activity.
