premise: Fishing<br>Dennis had not been fishing in a long time. He decided to take a small vacation from work to go fishing. The day before he left he made sure all his gear was in good shape. After he packed his car he headed to a local lake. After catching many fish he headed home.
hypothesis: Dennis took at least a couple days off work for fishing.
reason: The text only says he decided to take a small vacation from work to go fishing. He might have taken off a single day, since it sounds like a local trip and he went home. The model assumed vacation meant more time off.
