context: Chances are slight that Winona is a wolf. It is probably not the case that Julius is a swan. It is unlikely that John moved to the office. There is a better than even chance that if Julius is a swan, or John moved to the office, then Emily is a cat. There is almost no chance that if John moved to the office, or Julius is a swan, then Lily is a frog. We believe that if Winona is a wolf, or John moved to the office, then Brian is a rhino.
