premise: group of people sweeping the floor and cleaning
hypothesis: Some janitors are sweeping floors and cleaning the campus late at night.
explanation_1: Not all people sweeping the floor are janitors. The floor might not be on a campus. The people might not be cleaning at night.
explanation_2: Just becayse a group of people are sweeping and cleaning does not mean they're janitors.
explanation_3: Just because there is a group of people cleaning, it does not mean they are necessarily janitors. They also aren't necessarily on a campus or that it's late at night.
