context: We believe that Winona is a wolf. There is a better than even chance that Bill went to the bedroom. It is probable that Bernhard is a frog. It is probably the case that if either Bill went to the bedroom, or Bernhard is a frog, then Julius is gray. We doubt that if Winona is a wolf, and Bill went to the bedroom, then Brian is a lion. There is a very good chance that if Bernhard is a frog, and Winona is a wolf, then Lily is yellow.
hypothesis: It is probable that bill went to the bedroom, and Lily is yellow.
valid_hypothesis: It is probably not the case that bill went to the bedroom, and Lily is yellow.
invalid_hypothesis: It is probable that bill went to the bedroom, and Lily is yellow.
hypothesis_assertion: Bill went to the bedroom, and Lily is yellow.
