premise: Dance<br>Janet was concerned about her upcoming prom. Her prom was on Friday. She came to school Wednesday concerned about not having a date. Fortunately Ben also did not have a date. So Ben asked Janet to prom and both of their problems were solved.
hypothesis: She came to school Wednesday concerned about going to prom alone.
reason: If she is going to prom alone then she doesn't have a date. I don't think the system knows it is the same thing.
