premise: Vibrant colored dress wearing, long-haired women and men, under a bridge, dance in joy while a lone member holds up a peace sign with her hand. hypothesis: People dressed as hippies are getting their picture taken.
neutral: The description of the people dressed as hippies might be an accurate statement, but the description might be describing something else, so the word hippies cannot be inferred from sentence 1 and although you might know the group of people are getting their picture taken because you are looking at a picture of it, that cannot be inferred from sentence 1.
