context: There is a better than even chance that Julius is a lion. There is little chance that Fred went to the garden. Chances are slight that Bernhard is white. There is little chance that if Bernhard is white, or Julius is a lion, then Brian is green. It is probably not the case that if either Bernhard is white, or Julius is a lion, then Gertrude is a wolf. It is highly unlikely that if either Fred went to the garden, or Julius is a lion, then Daniel took the apple.
hypothesis: It is impossible that gertrude is a wolf, and Daniel took the apple.
valid_hypothesis: It is impossible that gertrude is a wolf, and Daniel took the apple.
invalid_hypothesis: We believe that gertrude is a wolf, and Daniel took the apple.
hypothesis_assertion: Gertrude is a wolf, and Daniel took the apple.
