premise: A man in a cap and white shirt is cutting some fish on a boat that is floating on water next to a wooden dock. hypothesis: a fisherman had a big day.
neutral: It is not clear from Sentence 1 that the man is, indeed, a fisherman (he could be some sort of butcher or assistant). It is also not clear that he had a "big day"—the amount of fish is not specified in Sentence 1.
