premise: In front of a laundromat and The Gulch of San Francisco, there is a man down on the ground, a man on a cellphone, and a couple of women walking by. hypothesis: People are going about their normal business in San Francisco, and in front of this laundromat is no exception.
entailment: The man on the ground, the man on a cellphone and the couple of women can be referred to collectively as 'People'. Also 'going about their normal business' is a simpler rephrasing of the individual actions they were said to be doing, 'down on the ground', 'on a cellphone', 'walking by'.
