From the options, the one that fits the requirements is C) since estaba matches the subject pronoun yo in the imperfect. On the other hand, caminando is the present participle of the verb caminar. Finally:

Marcos estaba estudiando cuando llegué a su casa

3) Correct answer:

4) Correct answer:

B) María estaba cocinando cuando ella se cortó

Recall that we said above that it's common to use the imperfect progressive to talk about an action that was interrupted in the past. In this way, estaba cocinando matches the imperfect progressive because estaba stands for the third person singular in the imperfect and cocinando is the present participle of the verb cocinar. Therefore, we must choose a verb in the preterite tense to complete the sentence, which is cortó. We choose the preterite because this tense talks about actions that were completed at a certain moment in the past. Finally, the sentence means:

Maria was cooking when she cut herself

5) Correct answer:

A) me lastimé el tobillo cuando estaba jugando futbol

Let's explain why this is the correct option. First of all, me lastimé stands in reflexive form, that is, me is the reflexive pronoun for the first person singular and lastimé matches the first person singular in the preterite. We use a reflexive pronouns with a verb to point out that a person carries out an action to or for himself/herself. So this conjugation tells us that the sentence is given in the past. On the other hand, estaba jugando stands for the imperfect progressive. Finally, we can translate this sentence as follows:

I hurt my ankle when I was playing soccer

6) Correct answer:

B) tú estabas escribiendo

This sentence is given in the imperfect progressive and we know it because the part of the sentence estabas escribiendo. Thus, tú translates into you and estabas escribiendo means were writing because estabas matches the subject pronoun tú in the imperfect and escribiendo is the present participle of the verb escribir,

7) Correct answer:

C) to express an ongoing action in the past that is interrupted

As we said above, this is the main use of this tense. So this is formed by the imperfect form of the verb estar plus a present participle. Therefore, we can write this as the following formula:

Imperfect of the verb estar + present participle.

So the present participle tells us that an action is in fact an ongoing action.

• A mí me gusta nadar

Since after the blank comes an infinitive verb, which is nadadr, then the conjugation of the verb gustar must match the singular form in the simple present. That's why we choose gusta instead of gustan.

• A ellas no les faltan cuadros para la exposición

Since after the blank comes a plural noun, which is cuadros, then the conjugation of the verb faltar must match the plural form in the simple present. So we choose faltan rather than falta.
