Leo: Given the sentence "An older gentlemen in red walks by an individual wearing all blue." is it true that "The older man walks past another individual."?
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.

If a person walks by an individual it implies he walks past someone.
Thus, the answer is yes.
