premise: The person is standing in the doorway beneath the tree.
hypothesis: There is a salesman at the door.
explanation_1: Standing in the doorway does not make someone a salesman.
explanation_2: Just because the person is standing in the doorway beneath the tree does not mean it is a salesman.
explanation_3: The person standing in the doorway is not necessarily a salesman. "At the door" suggests that the person is waiting to be let in, which the first sentence doesn't imply.
