Leo: Given the sentence "A man wearing a helmet has his hand up in the air and is shouting in a similar way the crowd behind his doing." is it true that "Two men sit contemplatively."?
Mei: OK, So, let's think first...
Me:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Must be a man or two men. Cannot sit contemplatively and shout in a crowd.
Thus, the answer is no.
