Consider the question. Given the sentence "A man does a wheelie on his bicycle on the sidewalk." can we conclude that "The man is a street performer and there is a crowd watching him."?
Options:
- yes
- it is not possible to tell
- no
 If the answer is 'it is not possible to tell'; explain the reasoning:
A man who does a wheelie on his bicycle is not necessarily a street performer and not necessarily with a crowd watching him.
