Answer to Question 1

C

Answer to Question 2

Price rises to 4 per gallon. Consumers purchase only 500 gallons of milk. The government purchases 1,000 gallons of milk to support the price at 4. Thus a total of 1,500 gallons is produced. The loss in social welfare equals 1,000 gallons of milk at 4/gallon (equals 4,000 ) less the producer surplus above the old demand curve up to a price of 4 (which is 500 ). The loss in social welfare is 3,500.
