context: It is improbable that Lily is a rhino. It is improbable that Mary moved to the garden. It is impossible that Bill left the milk. There is a better than even chance that if either Mary moved to the garden, or Bill left the milk, then Bernhard is a lion. We believe that if either Lily is a rhino, or Mary moved to the garden, then Brian is a frog. It is certain that if Mary moved to the garden, or Lily is a rhino, then John picked up the apple.
hypothesis: It is highly unlikely that either Bernhard is a lion, or Mary moved to the garden.
valid_hypothesis: It is highly unlikely that either Bernhard is a lion, or Mary moved to the garden.
invalid_hypothesis: It is certain that either Bernhard is a lion, or Mary moved to the garden.
