Question

1) Durante la fiesta nosotros ______

Answer 1

1. b.bailamos
2. a.tocan

Answer 2

Answer:

(1.) Durante la fiesta nosotros bailamos (2) mientras nuestros amigos tocan la guitarra y el piano.

Explanation:

I'm sure #1 is "bailamos"

But for #2 all of the answer choices do not sound right to me.

Are you sure those are the choices?

It should include "tocaban"  because otherwise the English translation for that sentence would be like this:

(1) During the party we danced(bailamos)(2) while our friends play(tocan) the guitar and the piano. (?!)

So I think this is the correct way to write the sentence:

• Durante la fiesta nosotros bailamos mientras nuestros amigos tocaban la guitarra y el piano. (past tense)

(1) During the party we danced  (2) while our friends played the guitar and the piano.

Sometimes textbooks are wrong in their translations.
