premise: Many people sit, some stand outside of a large brick building.
hypothesis: people are protesting outside of an abortion clinic
explanation_1: You can not infer they are protesting outside an abortion clinic.
explanation_2: People can sit and stand for numerous reasons that are not a protest and not all brick buildings are abortion clinics.  Without knowing this I wouldn't know what that they were protesting or what they were protesting.
explanation_3: Not all building is an abortion clinic and not all people standing outside of a building are protesting.
