premise: Guy in a blue shirt flipping burgers and hotdogs on an outdoor grill. hypothesis: A guy is baking a cake in the kitchen.
contradiction: A guy cannot be flipping burgers and baking a cake because those are two different types of cooking. Burgers and hotdogs are cookout food and a cake is dessert food. An outdoor grill is a cooking device used outside and the act of backing takes place indoors in a kitchen.
