context: It is probably not the case that John moved to the office. It is certain that Bernhard is a swan. Chances are about even that Greg is a swan. Chances are slight that if Bernhard is a swan, or John moved to the office, then Brian is a rhino. There is a very good chance that if Bernhard is a swan, and Greg is a swan, then Julius is gray. It is improbable that if either Greg is a swan, or John moved to the office, then Antoine is hungry.
