Leo: Can we conclude from "A man climbs up a rock while others wait for their turns." that "A man climbs a boulder to look for his friends."?
Options:
- yes
- no
- it is not possible to tell
Mei: OK, So, let's think first...
Me:
Not all rocks are a boulder and not all climbers are looking for friends.
Thus, the answer is it is not possible to tell.
