context: We believe that John grabbed the milk. There is little chance that Lily is a frog. There is almost no chance that Gertrude is a wolf. There is a very good chance that if either Gertrude is a wolf, or John grabbed the milk, then Julius is gray. We believe that if Gertrude is a wolf, or Lily is a frog, then Bernhard is a rhino. We doubt that if Gertrude is a wolf, and John grabbed the milk, then Mary picked up the apple.
