Answer 1

In Puerto Rico, you can non verbally ask "What's going on" by wiggling your nose. 

Answer 2

Answer: wiggling the nose.

Explanation: In Puerto Rico (and some other Spanish speaking countries), wiggling your nose is a way to, nonverbally, ask "What?" or "i don't understand you"

That is equivalent to say "What is going on?"

Then the right answer is the third option; wiggling the nose.
