Answer to Question 1

D

Answer to Question 2

An HHI of 2,500 does not in itself mean that the market is highly concentrated. For example, if there are only four firms in an industry, and each firm supplies 25 of the market, intense competition can actually exist among these four firms. This may be sufficient to drive the market equilibrium toward a competitive outcome. Empirical research has shown that the number of firms does not have to be very large to bring prices close to the competitive level.
