Carolina: ¿dónde has comprado las entradas?
sandra: aquí mismo. en esa enfrente
a. butaca
b. taquilla
c. galería
d. gallinero

B. Box office

Explanation:

To figure this out you just have to know what it means and it means:

    Carolina: Where did you buy the tickets?

    Sandra: Right here. In that in front

   Now that we know what the sentence means we will use the process of elimination to find the right answer. This is what every single word means:

A. Armchair

B. Box office

C. Gallery

D. Chicken coop

  To use process of elimination we just cross out the wrong answers. We automatically know that  C and D are wrong because they make no sense when put in the sentence. And we know that B will have to be correct since it is the only word that will fit into the sentence.
