premise: A man in a cap and red, blue, and white jacket looks off to the left while people are milling about behind him. hypothesis: A woman wearing a pink jacket is looking right while people are in front of her.
contradiction: A man is not a woman. A pink jacket is not a red blue and white jacket. Someone looking to the right cannot also be looking to the left. People cannot be in front of a person and behind a person at the same time. A person cannot be a him and a her.
