context: It is almost certain that Mary went to the hallway. It is impossible that Brian is a lion. It is certain that Daniel left the football. We doubt that if either Brian is a lion, or Daniel left the football, then Lily is white. It is impossible that if Mary went to the hallway, or Brian is a lion, then Julius is yellow. There is little chance that if Daniel left the football, or Brian is a lion, then John moved to the office.
