Student: Premise: "A man working on laying a new roof."
Based on this premise, can we conclude that the hypothesis "A man with a blue hat working on laying a new roof." is true?
Options:
- yes
- it is not possible to tell
- no.
Teacher: Let's think:
The man doesn't necessarily have on a blue hat. It could be any color or he may not have a hat on. So the final answer is it is not possible to tell.
