Leo: Premise: "An old woman with a white greyhound is standing on the sidewalk."
Based on this premise, can we conclude that the hypothesis "An old woman and a dog are waiting for someone." is true?
Options:
- yes
- it is not possible to tell
- no
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.

An old woman with a white greyhound standing on the sidewalk is not necessarily waiting for someone.
Thus, the answer is it is not possible to tell.
