context: It is unlikely that Daniel left the football. There is a very good chance that Bernhard is yellow. It is probably the case that Julius is a frog. We doubt that if Bernhard is yellow, or Daniel left the football, then Greg is a swan. We believe that if either Bernhard is yellow, or Daniel left the football, then Mary went to the hallway. It is probably not the case that if Julius is a frog, and Daniel left the football, then Brian is gray.
