Leo: Premise: "4 people are dressed in costumes dancing on stage."
Based on this premise, can we conclude that the hypothesis "There are 4 people who are friends." is true?
Options:
- yes
- it is not possible to tell
- no
Mei: OK, So, let's think first...
Me:
Four people do not have to be friends because they are dressed in costumes.
Thus, the answer is it is not possible to tell.
