<h2><u>Answers:</u></h2>
These sentences are written in Preterite Imperfect Indicative.
It is important to note this verbal tense is used in Spanish (castilian) <em>to express courses of past actions whose beginning and end are not specified.
</em>
Knowing this, let’s begin with the answers:
<h2>
1. Right answer: mirábamos
</h2>
Nosotros <u>mirábamos</u> mucha televisión.
We were watching a lot of television
This means the action of "watching television" performed by the <u>first person in plural </u>we, is indicated as an action in process, without defining whether it was completed or not.
This also would mean this is an action that used to happen in the past.
The options tomábamos (we were taking), vivíamos (we were living) and escribíamos (we were writing) are incorrect because do not match with the context of the sentence
<h2>2. Right answer: estudiaba
</h2>
Yo <u>estudiaba</u> por la noche para los exámenes.
I studied at night for exams
This means the action of "studying" performed by the <u>first person in singular</u> I, is indicated as an action in process, without defining whether it was completed or not.
The options escuchaba (I listened), era (I was) and iba (I went) are incorrect because do not match with the context of the sentence
