context: It is unlikely that Mary moved to the garden. There is little chance that John went to the hallway. There is little chance that Daniel got the apple. We believe that if John went to the hallway, and Daniel got the apple, then Fred is in the bedroom. It is impossible that if John went to the hallway, and Mary moved to the garden, then Bernhard is a swan. It is highly unlikely that if Daniel got the apple, or John went to the hallway, then Brian is a lion.
