premise: A woman is standing on the sidewalk, in front of a crosswalk.
hypothesis: A crossing guard waits for school to let out.
explanation_1: A woman is not necessarily a crossing guard.
explanation_2: Just because a woman is standing on the sidewalk, in front of a crosswalk it does not mean a crossing guard waits for school to let out.
explanation_3: If the sentences didn't follow one another, you wouldn't even be able to telling they are part of the same story. Crossing guards work at crosswalks, and often the guard waits for school to let out so they can start doing their jobs. But Sentence 1 doesn't say whether the woman is a crossing guard or sees one, or even says anything about being near a school or a route used by students.
