context: There is a very good chance that Lily is a swan. There is little chance that Brian is a frog. It is likely that Bernhard is a rhino. Chances are slight that if Lily is a swan, or Bernhard is a rhino, then Julius is white. We believe that if Brian is a frog, or Lily is a swan, then Mary went to the hallway. We doubt that if Bernhard is a rhino, or Brian is a frog, then Greg is a rhino.
hypothesis: There is a better than even chance that mary went to the hallway, or Brian is a frog.

invalid_hypothesis: Chances are slight that mary went to the hallway, or Brian is a frog.
