premise: A girl wearing a brown jacket and jeans is sitting on a rock wall at the edge of a hill, there are several small carts in the background. hypothesis: A girl wearing a denim jacket and brown pants sits on a concrete wall at the edge of a cliff, there are several cows in the background.
contradiction: A denim jacket is typically blue, not brown; similarly, jeans are typically blue, unlike brown pants; a rock is not the same as concrete; a hill is not a cliff; carts are not the same as cows.
