context: We doubt that Lily is a rhino. It is highly likely that Julius is white. It is unlikely that Bernhard is a lion. It is almost certain that if Bernhard is a lion, and Lily is a rhino, then Greg is green. Chances are slight that if Bernhard is a lion, or Lily is a rhino, then Brian is gray. There is a better than even chance that if either Lily is a rhino, or Julius is white, then John moved to the garden.
hypothesis: It is highly unlikely that greg is green, or John moved to the garden.
valid_hypothesis: Chances are about even that greg is green, or John moved to the garden.
invalid_hypothesis: It is highly unlikely that greg is green, or John moved to the garden.
hypothesis_assertion: Greg is green, or John moved to the garden.
