context: It is impossible that John went to the office. It is highly likely that Julius is a swan. It is likely that Bernhard is green. We doubt that if Julius is a swan, and John went to the office, then Emily is a cat. It is likely that if Bernhard is green, and Julius is a swan, then Mary moved to the garden. It is certain that if either Julius is a swan, or Bernhard is green, then Lily is white.
