Student: Test for natural language inference.
Premise: "A man wearing a professional blue suit and protective glasses is trying to open a locker with a tool."
Hypothesis: "A man is a locksmith."
Is the hypothesis entailed by the premise?
Options:
- yes
- no
- it is not possible to tell.
Teacher: Let's think:
People of many different professions wear blue suits and protective glasses and people other than locksmiths can try to open a locker with a tool so that doesn't necessarily tell us he is a locksmith. So the final answer is it is not possible to tell.
