Student: Test for natural language inference.
Premise: "A man in green and a woman in a gray sweater are looking at some unidentified object."
Hypothesis: "A man and a woman are napping together on a sofa."
Is the hypothesis entailed by the premise?
Options:
- yes
- no
- it is not possible to tell.
Teacher: Let's think:
A man and woman who are looking at some unidentified object are probably not napping together on the sofa at the same time. So the final answer is no.
