1) Correct answer:

C) estaba caminando

The imperfect progressive is used when talking about what a person was doing.One of the main uses this tense is to talk about an action that was interrupted in the past. This tense is formed with the verb estar (conjugated in the imperfect) plus a verb in present participle. 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:

Estaba caminando y me caí

2) Correct answer:

A) estaba estudiando

Since Marcos can be replaced by the subject pronoun él, that is, this sentence matches the third person singular, then we must conjugate the verb estar in the imperfect and matching this person as well. So the correct conjugation is estaba and the present participle of the verb estudiar is estudiando. Finally, the correct option is A)  and we can write:

Marcos estaba estudiando cuando llegué a su casa

3) Correct answer:

C) estaban jugando

Since ellos is the subject pronoun that matches the third person plural, we must we must conjugate the verb estar in the imperfect an matching this person as well. Thus, the correct conjugation is estaban and the present participle of the verb jugar is jugando. Finally, the correct option is C) and we can write:

Ellos estaban jugando futbol cuando se lastimaron

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.
