context: We doubt that Greg is a swan. There is a very good chance that John went to the bedroom. We doubt that Lily is yellow. It is improbable that if Lily is yellow, and Greg is a swan, then Antoine is hungry. There is little chance that if Greg is a swan, and John went to the bedroom, then Julius is a rhino. It is unlikely that if either Greg is a swan, or John went to the bedroom, then Brian is green.
hypothesis: It is impossible that antoine is hungry, and Brian is green.
valid_hypothesis: It is impossible that antoine is hungry, and Brian is green.
invalid_hypothesis: We believe that antoine is hungry, and Brian is green.
hypothesis_assertion: Antoine is hungry, and Brian is green.
