premise: There is a group of children getting their picture taken with presents.
hypothesis: Two men carry a Christmas tree.
explanation_1: A group of children cannot also be two men
explanation_2: There must either be men or children.  A group would be more than two.
explanation_3: A group of children and two men are not the same thing. Usually one would not be getting a picture taken with presents while carrying a Christmas tree.
