context: There is a very good chance that Mary went to the hallway. We doubt that Gertrude is a wolf. We believe that Brian is a lion. Chances are about even that if Gertrude is a wolf, or Mary went to the hallway, then Lily is a swan. There is almost no chance that if either Mary went to the hallway, or Gertrude is a wolf, then John left the milk. It is probably the case that if Gertrude is a wolf, or Mary went to the hallway, then Bernhard is a rhino.

valid_hypothesis: There is a better than even chance that gertrude is a wolf, or Bernhard is a rhino.
invalid_hypothesis: Chances are slight that gertrude is a wolf, or Bernhard is a rhino.
