context: We doubt that Lily is a rhino. It is highly likely that Mary moved to the garden. We doubt that Julius is a swan. It is highly unlikely that if Lily is a rhino, and Mary moved to the garden, then Bernhard is gray. It is almost certain that if Lily is a rhino, or Julius is a swan, then Greg is a lion. It is impossible that if Mary moved to the garden, or Julius is a swan, then John put down the milk.
hypothesis: It is probably not the case that either Greg is a lion, or Bernhard is gray.
valid_hypothesis: It is probably not the case that either Greg is a lion, or Bernhard is gray.
invalid_hypothesis: It is highly likely that either Greg is a lion, or Bernhard is gray.
