context: It is highly unlikely that Daniel took the milk. It is highly likely that Greg is yellow. We believe that Bernhard is a frog. It is unlikely that if Bernhard is a frog, and Greg is yellow, then Brian is a swan. It is likely that if Greg is yellow, or Daniel took the milk, then Fred went to the bedroom. It is probable that if Bernhard is a frog, and Daniel took the milk, then Lily is a rhino.
hypothesis: There is almost no chance that lily is a rhino, and Bernhard is a frog.
valid_hypothesis: There is almost no chance that lily is a rhino, and Bernhard is a frog.
invalid_hypothesis: It is probably the case that lily is a rhino, and Bernhard is a frog.
