context: It is certain that Brian is a frog. It is certain that Sumit is thirsty. There is little chance that Daniel grabbed the apple. It is almost certain that if Sumit is thirsty, and Brian is a frog, then Sandra took the milk. It is improbable that if either Brian is a frog, or Daniel grabbed the apple, then Julius is a swan. We doubt that if Sumit is thirsty, or Brian is a frog, then Mary went to the bedroom.
hypothesis: There is a very good chance that julius is a swan, or Mary went to the bedroom.
valid_hypothesis: It is probably not the case that julius is a swan, or Mary went to the bedroom.
invalid_hypothesis: There is a very good chance that julius is a swan, or Mary went to the bedroom.
hypothesis_assertion: Julius is a swan, or Mary went to the bedroom.
