ANSWER: TRUE
EXPLANATION: The sentence is true that the result of market economies are companies competing with each other. In a market, if there are no competitions between companies, then the market can not be termed as healthy.
The competition between the companies create ups and downs in the market and simultaneously create demand for a particular product or service. The rival companies try to create a better product or service by innovation and try to grab more consumers at better pricing. These exercises create rotation of money in the market thus making better economies of the market as well as of the country.
