premise: a large group of people standing behind a podium on the stairs of a congress building.
hypothesis: A mob prepares to protest a speaker.
explanation_1: A group of people standing behind a podium on the stairs of a congress building are not necessarily preparing to protest a speaker.
explanation_2: A large group of people can congregate without the intention of having a protest.
explanation_3: A large group of people does not automatically create a mob. People behind a podium could be there for support instead of to protest a speaker.
