Leo: Premise: "The black dog is sniffing the brown dog's butt."
Hypothesis: "Two dogs meet each other for the first time."

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.

The fact that black dog is sniffing the brown dog's butt doesn't imply dogs meet each other for the first time.
Thus, the answer is it is not possible to tell.
