context: We believe that Mary grabbed the milk. Chances are about even that Winona is a wolf. Chances are slight that Brian is yellow. It is improbable that if either Brian is yellow, or Mary grabbed the milk, then Julius is white. Chances are about even that if Winona is a wolf, or Brian is yellow, then Bernhard is a rhino. There is almost no chance that if Brian is yellow, and Winona is a wolf, then Emily is a sheep.
hypothesis: Chances are about even that either Emily is a sheep, or Winona is a wolf.
valid_hypothesis: Chances are about even that either Emily is a sheep, or Winona is a wolf.
invalid_hypothesis: It is impossible that either Emily is a sheep, or Winona is a wolf.
