context: It is likely that Sandra left the apple. It is certain that Bernhard is a swan. We believe that Greg is a rhino. It is improbable that if either Greg is a rhino, or Sandra left the apple, then Brian is a lion. It is probably the case that if Greg is a rhino, or Bernhard is a swan, then Mary went to the bedroom. There is a better than even chance that if either Greg is a rhino, or Sandra left the apple, then Lily is a frog.
hypothesis: It is unlikely that lily is a frog, or Sandra left the apple.
valid_hypothesis: There is a very good chance that lily is a frog, or Sandra left the apple.
invalid_hypothesis: It is unlikely that lily is a frog, or Sandra left the apple.
