- 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.

Workers standing in work zone may or not be hard at work.
Thus, the answer is it is not possible to tell.
