Leo: Premise: "Children playing in a river."
Based on this premise, can we conclude that the hypothesis "Children napping on the bank of a river." is true?
Options:
- yes
- it is not possible to tell
- no
Mei: OK, So, let's think first...
Me:
Playing and napping are mutually exclusive activities. The children cannot be both in a river and on the bank of a river (which means that you are next to a river).
Thus, the answer is no.
