The following conditions must apply: Used pop is on sale; new opera is not. If both types of pop are on sale, then all soul is. If both types of jazz are on sale, then no rap is. If neither type of jazz is on sale, then new pop is. If either type of rap is on sale, then no soul is. Which one of the following could be a complete and accurate list of the types of CDs that are on sale?
