Leo: Can we conclude from "Two workers are wearing hard hats while one of them begins to descend into a floor hatch." that "They are working in a mine."?
Options:
- yes
- no
- it is not possible to tell
Mei: OK, So, let's think first...
Me:
Workers descending into a floor hatch are not necessarily working in a mine.
Thus, the answer is it is not possible to tell.
