Student: Premise: "The man is fishing with a cast net on a very small boat."
Based on this premise, can we conclude that the hypothesis "A fisherman tries to catch sharks on his small rowboat." is true?
Options:
- yes
- it is not possible to tell
- no.
Teacher: Let's think:
Cast a net does not imply to try to catch sharks. So the final answer is it is not possible to tell.
