context: It is improbable that Daniel grabbed the apple. We doubt that Bernhard is a frog. It is almost certain that Lily is yellow. There is almost no chance that if Lily is yellow, or Daniel grabbed the apple, then Sandra left the apple. It is probably the case that if Bernhard is a frog, and Daniel grabbed the apple, then Greg is green. We doubt that if either Lily is yellow, or Bernhard is a frog, then Julius is a rhino.
hypothesis: It is impossible that julius is a rhino, and Greg is green.
