context: There is a better than even chance that John is in the bedroom. It is likely that Mary went to the garden. Chances are slight that Daniel dropped the apple. We doubt that if Daniel dropped the apple, and Mary went to the garden, then Sandra took the football. We believe that if Mary went to the garden, or Daniel dropped the apple, then Bernhard is a lion. It is highly likely that if John is in the bedroom, and Daniel dropped the apple, then Lily is green.
hypothesis: It is highly unlikely that lily is green, and John is in the bedroom.
valid_hypothesis: It is highly unlikely that lily is green, and John is in the bedroom.
invalid_hypothesis: It is probably the case that lily is green, and John is in the bedroom.
