context: We believe that Greg is white. It is probable that Julius is gray. Chances are about even that Bill dropped the milk. It is impossible that if either Greg is white, or Bill dropped the milk, then Bernhard is a lion. It is probably the case that if Greg is white, and Bill dropped the milk, then Mary went to the bedroom. Chances are about even that if either Bill dropped the milk, or Julius is gray, then Lily is a lion.

valid_hypothesis: It is impossible that lily is a lion, and Bernhard is a lion.
