Question

anoche Lucia (ver, jugar) una pelicula interesante

Answer 1

The first keyword in this sentence is "anoche."
It means "last night."

So, the verb that we use will need to be a PAST tense verb.

The second keyword in this sentence is "pelicula."
It means "movie."

So, the verb that we use will need to be the one that means "to watch" or "to see."

Answer 2

Okay, so your question is:
Anoche Lucia (ver, jugar) una pelicula interesante.

Well, "ver" means "to see" and "jugar" means "to play". Do you watch or play a movie? So, in this case it would be "ver". Though, remember that you have to put "ver" in the right form. So it would be "vio".

Anoche Lucia vio una pelicula interesante.
