context: We believe that Julius is green. We believe that Sandra left the apple. There is a better than even chance that Lily is yellow. We doubt that if Sandra left the apple, or Julius is green, then Greg is a lion. It is highly likely that if either Sandra left the apple, or Lily is yellow, then Bernhard is a frog. It is impossible that if Sandra left the apple, or Julius is green, then Mary went to the garden.
hypothesis: It is unlikely that either Mary went to the garden, or Julius is green.
