context: We doubt that Daniel dropped the apple. There is almost no chance that Greg is a lion. We believe that Julius is a frog. It is probably the case that if either Julius is a frog, or Daniel dropped the apple, then Winona is a wolf. It is certain that if Julius is a frog, and Greg is a lion, then Lily is white. It is unlikely that if either Daniel dropped the apple, or Greg is a lion, then Bill went to the bedroom.
hypothesis: It is impossible that bill went to the bedroom, and Greg is a lion.
valid_hypothesis: It is impossible that bill went to the bedroom, and Greg is a lion.
