Leo: Given the sentence "A businessman looking out his door." is it true that "A man is looking at his co-worker."?
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 businessman looking out his door is necessarily looking at his co-worker.
Thus, the answer is it is not possible to tell.
