context: It is probably not the case that John went to the bedroom. We believe that Bill dropped the milk. It is certain that Bernhard is white. It is highly unlikely that if Bernhard is white, and John went to the bedroom, then Lily is a frog. It is unlikely that if Bill dropped the milk, and Bernhard is white, then Julius is a swan. We doubt that if Bill dropped the milk, or John went to the bedroom, then Mary left the apple.
hypothesis: It is unlikely that mary left the apple, or Lily is a frog.
valid_hypothesis: It is unlikely that mary left the apple, or Lily is a frog.
invalid_hypothesis: There is a very good chance that mary left the apple, or Lily is a frog.
hypothesis_assertion: Mary left the apple, or Lily is a frog.
