context: There is a very good chance that Fred dropped the apple. It is likely that Greg is a rhino. It is almost certain that Bernhard is a swan. It is highly likely that if either Greg is a rhino, or Fred dropped the apple, then Brian is green. It is probably not the case that if Bernhard is a swan, and Greg is a rhino, then Julius is yellow. Chances are slight that if Greg is a rhino, and Bernhard is a swan, then John put down the milk.
