context: There is a very good chance that Brian is white. It is improbable that Bernhard is a frog. We believe that Julius is a lion. We doubt that if either Julius is a lion, or Brian is white, then Jessica is a wolf. There is little chance that if Bernhard is a frog, or Julius is a lion, then Mary put down the apple. Chances are about even that if Julius is a lion, or Bernhard is a frog, then Yann is thirsty.

valid_hypothesis: It is highly unlikely that yann is thirsty, and Bernhard is a frog.
invalid_hypothesis: There is a better than even chance that yann is thirsty, and Bernhard is a frog.
