premise: Interior scene of fairly full tour bus.
hypothesis: There are men and women on the bus.
explanation_1: The full bus doesn't imply there are both men and women on it.
explanation_2: Just because the tour bus is full does not mean men and women are on the bus.
explanation_3: If a bus is full, it may be full of people, objects, gas, animals et cetera, therefore one cannot assume that people are on the bus and if there are people on the bus, those people may be men or women or a combination.
