Question

No voy ___________ al estadio.

Answer 1

Nada - nothing
Nadie - no one
Nunca - never

No voy nunca al estadio translates to "I'm never going to the stadium" so I believe Nunca is the answer

Answer 2

Right answer:

nunca

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)
