context: It is improbable that John is in the bedroom. There is little chance that Lily is a swan. There is almost no chance that Antoine is hungry. There is a better than even chance that if Lily is a swan, and Antoine is hungry, then Bill went to the kitchen. There is a very good chance that if Lily is a swan, or Antoine is hungry, then Julius is a frog. It is likely that if Antoine is hungry, and Lily is a swan, then Daniel dropped the apple.
hypothesis: Chances are slight that either Julius is a frog, or Daniel dropped the apple.
valid_hypothesis: Chances are slight that either Julius is a frog, or Daniel dropped the apple.
invalid_hypothesis: It is probable that either Julius is a frog, or Daniel dropped the apple.
