Options:

- 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.

A dog can play catch with other people besides his owner.
Thus, the answer is it is not possible to tell.
