A well-known western economist once said that a country can create wealth and become rich if it can operate its economy effectively; and if such a country wants to maintain political stability, the wealth it creates must be distributed fairly; The fair distribution of wealth will end economic risks; however, the existence of economic risks is an indispensable prerequisite for effective economic operation. Can we know from this text? ['It is impossible for a country to coexist politically and economically.', 'It is impossible for a country to coexist politically and economically effectively.', 'The economic operations of a rich country must be efficient.', 'In a country where economic operations are ineffective, wealth must be fairly distributed.']
