Answer to Question 1

A

Answer to Question 2

No other market structure has the characteristic that one firm's actions can affect the actions of its competitors. In monopoly, there are no competitors to affect. And in perfect competition and monopolistic competition, there are so many competitors that any one firm's actions have no measurable impact on its competitors. Oligopoly is unique in that it is the only market structure in which one firm's actions affect the actions of its competitors.
