• We were supposed to change the sentence to past perfect tense.
• To do so, we will first identify the verb of the given sentence.
• Then, we will convert it to the past perfect tense according to the syntax: had + verb (past tense).
• Past perfect tense can be used when we want to show that an action has already finished in the past before some point of time.
