Leo: Premise: "A boy with a helmet skateboards across the street."
Based on this premise, can we conclude that the hypothesis "A boy knows how to do tricks on a skateboard." is true?
Options:
- yes
- it is not possible to tell
- no
Mei: OK, So, let's think first...
Me:
Skateboards across the street does not necessarily mean knows how to do tricks.
Thus, the answer is it is not possible to tell.
