premise: A small dark-haired boy climbing in a large tree.
hypothesis: A small dark-haired boy wearing a blue shirt is climbing in a large tree with a tree house in it.
explanation_1: The may boy may not be wearing a blue shirt, and there may be no tree house in it.
explanation_2: Just because a boy is climbing a tree it does not mean there is a tree house in it.  A tree does not have to be large.  The boy does not have to be wearing a blue shirt.
explanation_3: The large tree does not necessarily have a tree house in it and the boy does not necessarily have to be wearing a blue shirt.
