Answer to Question 1

D

Answer to Question 2

The statement is incorrect. Oligopoly is an industry in which only a few firms compete. Because there are only a few firms, the hallmark of oligopoly is mutual interdependence, that is, one firm's action will affect the other firms. The fact that in oligopoly each firm's actions affect its rivals is unlike the case in perfect competition or monopolistic competition, in which there are so many firms that one firm's actions have no effect on its rivals, or monopoly, in which there is only one firm and hence no rivals.
