Leo: Premise: "A man in a black shirt swings his golf club."
Hypothesis: "The golfer in the black shirt missed his ball."

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.

Swinging golf club by the man does not imply that he missed his ball.
Thus, the answer is it is not possible to tell.
