premise: An Asian boy in glasses and a yellow shirt holds a blue bag while standing between two parking spaces on the street. hypothesis: The boy is playing a tuba in the middle of the ocean.
contradiction: Sentence one describes an asian boy, what he is wearing, his location and the action he performing, sentence two does not provide the ethnicity of the boy or what he is wearing, just the action and location. The actions and the locations of the boys both differ in that the boy in sentence one is standing in the street, while the boy in sentence two is playing an instrument in the middle of the ocean.
