context: It is certain that Lily is a lion. It is improbable that John is in the hallway. There is a better than even chance that Julius is a rhino. We doubt that if Lily is a lion, or John is in the hallway, then Mary moved to the office. It is highly unlikely that if Julius is a rhino, or Lily is a lion, then Brian is gray. Chances are slight that if either John is in the hallway, or Lily is a lion, then Winona is a cat.
