No voy al estadio.
nada
nadie
nunca
which is the answer to this question?

Nunca is an adverb of time. Adverbs of time give information on time, duration, and frequency answering questions like When? and How often? Recall that an adverb is a word or group of words that describes or modifies a verb, adjective, another adverb or a whole sentence. The other words nada means nothing and nadie means no one, so these can't be the answers. Finally:

No voy nunca al estadio (I'm never going to the stadium)

do you know the title of the listening so i can hear and answer this?

toilet paper: papel higienico

polar bear: oso polar

elephant: elefante

the only thing that makes sense that you couldn't find in a porta-potty, that should be there, would be toilet paper.

hope this
