premise: A brown-haired woman wearing glasses, a black long-sleeved shirt and pin striped pants flipping through a book and smiling as a blond woman wearing a white sweatshirt and a white shoulder bag on her right shoulder watches smiling. hypothesis: A man with brown hair is near another man with brown hair and they are frowning.
contradiction: The first person is either a brunette man or woman. The second person cannot be both a man and a woman, and cannot be both brown haired and blonde. The people cannot be smiling and frowning simultaneously.
