explanation: a "singer" can be "chinese" and a "chinese" can also be a "singer". "guitarists" can "play", and a "guitarist" is not "play" itself. "scholars" can do "research", and "scholars" are not "research" itself. "LeBron James" must be from "Ohio", and there is no other possibility. some "experts" are "teachers", and some "teachers" are "experts".
