The statement that the De Beers group of South Africa was viewed as a monopoly for most of the 1900s is True.
What is a Monopoly ?
A monopoly is a market arrangement where one producer or seller holds a disproportionate amount of power within a certain market. Monopolies are forbidden in free-market economies as they limit customer alternatives and impede competition.
