Explanation:
You have to make one sentence from the two given, using Pretérito Pluscuamperfecto tense.
The Pretérito Pluscuamperfecto tense of perfect indicative is said to be the time we use to talk in the past about the past, which may seem far-fetched but, nevertheless, it is quite graphic: with the super-perfect we tell something that has already happened and is subordinated to another fact or action also passed for example.
It is formed with the past tense of the auxiliary verb ‘haber‘ + the participle of the verb that describes the action we are talking about.
