Leo: If "A group of men who are working on the power lines." does that mean that "The men are working with a downed power line."?
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.

Working on the power lines does not mean that it is downed power line.
Thus, the answer is it is not possible to tell.
