Leo: Premise: "Guy doing a head spin while wearing a helmet."
Based on this premise, can we conclude that the hypothesis "The guy is riding a bike." is true?
Options:
- yes
- it is not possible to tell
- no
Mei: OK, So, let's think first...
Me:
Doing a head spin does not imply that the guy is riding a bike.
Thus, the answer is it is not possible to tell.
