Consider the question. Premise: "A boy is inside holding something on top of his head."
Based on this premise, can we conclude that the hypothesis "The boy has a ball of wax on his head." is true?
Options:
- yes
- it is not possible to tell
- no
 If the answer is 'no'; explain the reasoning:
A boy cannot be holding something on his head while a ball of wax is already there.
