context: There is little chance that John went to the bedroom. It is impossible that Daniel is in the garden. Chances are about even that Bernhard is a rhino. It is certain that if John went to the bedroom, and Daniel is in the garden, then Brian is gray. There is almost no chance that if John went to the bedroom, or Bernhard is a rhino, then Lily is green. Chances are about even that if either Bernhard is a rhino, or Daniel is in the garden, then Jeff dropped the apple.
hypothesis: There is a better than even chance that either Brian is gray, or Lily is green.
valid_hypothesis: There is almost no chance that either Brian is gray, or Lily is green.
invalid_hypothesis: There is a better than even chance that either Brian is gray, or Lily is green.
