Answer 1

we went for a walk after the rain had stopped

Answer 2

We went for a walk after the rain had stopped.

In the above solution, we see the usage of the simple past tense.

• Tenses are words that signify or portray the time or tenure of an activity, event, or phenomenon.
• For example, It rained yesterday. Here, the word 'rained' is in the simple past tense.
• By this, we understand that the phenomenon or event that is being spoken about has already ended and thus, is in the past.

Thus, we understand that the action that is being spoken about in the question has already taken place and thus, is in the past.
