Explanation:
I have been able to complete the English exercise above by picking the correct answers.
In the above selected answers, you will see the use of simple past tense and past perfect tense.
Simple past tense is actually the tense that talks about a time before now that a particular action was completed. The time at which the action was carried out could be in the recent past or distant past.
While the past perfect tense talks about the verb form that refers to the action which was carried out at a time earlier than a time that is past which is being referred to.
