Leo: Given the sentence "A man sits in front of a wall with art pictures on it." is it true that "A man sits on a beach."?
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 either sits in front of a wall or is on a beach.
Thus, the answer is no.
