context: We doubt that Sandra got the apple. We doubt that Lily is gray. Chances are slight that Brian is green. There is a very good chance that if Lily is gray, or Brian is green, then Daniel left the apple. We believe that if Sandra got the apple, and Brian is green, then Greg is white. It is probably the case that if either Brian is green, or Lily is gray, then John went to the hallway.
