Leo: Given the sentence "White man in a black suit is crossing a busy street." is it true that "A man is sitting on a couch."?
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.

A man cannot be crossing a street while he is sitting on a couch.
Thus, the answer is no.
