Answer:
The correct answer is: maximized; reducing; increasing.
Explanation:
An oligopoly market is a market structure in which there is a small number of firms. The business decisions of each firm affect its competitors. There is no restriction on entry and exit of firms. There is a high degree of competition between firms.
The firms can maximize their profits if they collude and act like a monopoly. They can earn monopoly profits by reducing the level of output and increasing the price of products.
