context: We believe that Bernhard is a frog. It is unlikely that John went to the garden. It is improbable that Greg is yellow. There is a better than even chance that if Greg is yellow, or John went to the garden, then Mary took the apple. It is improbable that if either Greg is yellow, or John went to the garden, then Lily is a rhino. There is little chance that if Bernhard is a frog, and Greg is yellow, then Gertrude is a wolf.
hypothesis: It is impossible that either Lily is a rhino, or Bernhard is a frog.
valid_hypothesis: We believe that either Lily is a rhino, or Bernhard is a frog.
invalid_hypothesis: It is impossible that either Lily is a rhino, or Bernhard is a frog.
hypothesis_assertion: Either Lily is a rhino, or Bernhard is a frog.
