premise: A man wearing a red plaid kilt, black running shoes, and a cap with a feather carries a plastic shopping bag through the crowd in an outdoor plaza. hypothesis: a woman with red shows carries a bag in the empty field.
contradiction: A man is different from a woman. A woman is unlikely to be wearing a kilt and red is a different color than black is. Crowd is a group of people an empty field would have no people in it. An outdoor plaza would be man made and an empty field would be natural.
