Step-by-step explanation:
The past tense is used to tell about events that took place sometime in the past. Depending on the nature of the event, we will use different types of past tense. Here, we have the past simple and past perfect.
The past simple tense is used to talk about things that happened or existed before now.
The past perfect tense is used to show that one event happened before another in the past (e.g. We had watched TV before we played video games - one event took place before another).
