choices.label: A B C D
choices.text: bonus:reward:incentive solar eclipse:celestial body:universe entertainment:games:health peking opera:art:beauty
explanation: the means of "promotion" is "discount", and "competition" is the purpose of "promotion". the means of "reward" is "bonus", and "incentive" is the purpose of "reward". "solar eclipse" is a kind of astronomical phenomenon, and there is no obvious logical relationship between "solar eclipse" and "celestial body". the meaning of "entertainment" is "game", but the order of words is reversed from the query. "peking opera" is a kind of "art".
