premise: Under the glaring light of a fluorescent bulb, men in dark clothing and hats approach fare card machines; one older man in a blue scarf glances up as he puts on his gloves. hypothesis: The men are wearing bright suits in the park.
contradiction: It doesn't make sense to be wearing dark clothing and bright suits at the same time and the light bulb implies the would be inside, not outside at the park.|contradiction: Dark and bright are opposing contrasts of light.   Hats and suits are different articles of clothing. One man is singular to men-which is plural.|contradiction: Men cannot wear dark clothing and bright suits at the same time.
