Answer to Question 1

D

Answer to Question 2

Short run: An increase in demand raises equilibrium price and quantity. Existing firms produce more (because the higher price means that MR=MC at a higher quantity) and earn positive economic profits.

Long run: Positive profits attract new firms into the industry. The increase in supply reduces price and further increases quantity. Firms continue to enter until economic profits return to zero, and there is no further incentive for entry.
