context: We doubt that John went to the garden. We doubt that Brian is a swan. It is improbable that Daniel got the milk. Chances are slight that if Brian is a swan, and John went to the garden, then Fred moved to the office. It is probably not the case that if either Daniel got the milk, or Brian is a swan, then Jessica is a mouse. There is almost no chance that if either Brian is a swan, or John went to the garden, then Lily is a frog.
