Answer 1

1. habían (plusquamperfect preterit)

2. hemos (composed perfect preterit)

3. habías (plusquamperfect preterit)

4. había (plusquamperfect preterit)

5. he (composed perfect preterit)

6. había (plusquamperfect preterit)

Step-by-step explanation:

These are all in two tenses: either plusquamperfect preterit (also known as pluperfect) or composed perfect preterit. They both form with the proper person of the verb plus the verb "haber". However, they have different uses. Plusquamperfect preterit refers to a time in the past earlier than a previously mentioned time. For example in number 4 we know Tomás arrived to the airport and then saw the plane had not landed yet, although both actions are in the past, one happened before the other. In composed perfect preterit, we refer to an action that occurred very recently and has finished. For example in number 2, the visit happened today which is fairly recent but not going on anymore.
