Answer to Question 1

Every firm in a competitive market is so small that it can increase production without affecting the price of the good. Therefore a firm in a perfectly competitive market faces a perfectly elastic demand curve. The market demand curve is downward-sloping, which reflects the law of demand: consumers will purchase higher quantities of a good at lower prices and lower quantities at higher prices.

Answer to Question 2

B
