context: We believe that Lily is a swan. There is a better than even chance that Sandra dropped the milk. There is a better than even chance that John left the apple. It is likely that if either Lily is a swan, or Sandra dropped the milk, then Emily is a wolf. We doubt that if John left the apple, or Lily is a swan, then Bernhard is yellow. It is improbable that if Lily is a swan, or John left the apple, then Brian is a lion.
hypothesis: There is a very good chance that bernhard is yellow, and Brian is a lion.
valid_hypothesis: There is almost no chance that bernhard is yellow, and Brian is a lion.
invalid_hypothesis: There is a very good chance that bernhard is yellow, and Brian is a lion.
