context: It is improbable that Bill went to the garden. Chances are about even that Sandra grabbed the milk. It is impossible that Emily is a wolf. It is improbable that if Emily is a wolf, or Bill went to the garden, then Jason is bored. There is a better than even chance that if Emily is a wolf, and Bill went to the garden, then Winona is a mouse. We believe that if Sandra grabbed the milk, or Emily is a wolf, then Bernhard is a lion.
hypothesis: It is probably not the case that either Winona is a mouse, or Bernhard is a lion.
valid_hypothesis: It is probably not the case that either Winona is a mouse, or Bernhard is a lion.
invalid_hypothesis: It is likely that either Winona is a mouse, or Bernhard is a lion.
