Leo: Premise: "A group of boys play flag football while some bystanders watch."
Based on this premise, can we conclude that the hypothesis "A group of friend playing a flag football tournament." is true?
Options:
- yes
- it is not possible to tell
- no
Mei: OK, So, let's think first...
Me:
Not all boys are a friend. Playing tag football is not necessarily a flag football tournament.
Thus, the answer is it is not possible to tell.
