Объяснение:

Past Simple используется, когда существует указание на конкретный момент в прошлом или когда важно подчеркнуть последовательность действий.

Past Perfect еще называют предпрошедшим, т.к. эта форма показывает, что действие совершилось раньше, чем другое, или чем прошел какой-то определенный период в прошлом.
