Leo: Given the sentence "A customs officer leaning on a bike rack outside of an office building." is it true that "A customs officer smokes a cigarette during a quick break."?
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.

Leaning on a rack does not imply he smokes a cigarette.
Thus, the answer is it is not possible to tell.
