context: We doubt that Bernhard is white. It is almost certain that John moved to the office. There is almost no chance that Gertrude is a wolf. It is highly likely that if either John moved to the office, or Gertrude is a wolf, then Brian is gray. Chances are slight that if John moved to the office, or Bernhard is white, then Greg is a rhino. It is highly likely that if Gertrude is a wolf, and Bernhard is white, then Julius is white.
