Student: Premise: "Sunbathers frolic on the beach under a bright sun."
Hypothesis: "There are no sunbathers on the beach."
Is the hypothesis entailed by the premise?
Options:
- yes
- it is not possible to tell
- no.
Teacher: Let's think:
There either are or are not sunbathers on the beach; it is not possible for them to be both present and absent at the same time. So the final answer is no.
