#2 A decrease in quantity demanded is given by a(n):
downward shift of the demand curve. upward shift of the demand curve. downward movement to the right along the demand curve. upward movement to the left along the demand curve. downward shift of both demand and supply curves

Free Response 1 Last year a very severe ice storm hit the north counties of New York state, and the states of Vermont and Maine. Electric poles were down and no one had power for days. It was reported that the price of kerosene heaters skyrocketed and the number purchased increased during this time. Using a supply and demand diagram, show the impact of the ice storm on the market for kerosene heaters.

Free Response 2 Consumers can use either natural gas or heating oil to warm their houses. Suppose the price of natural gas increases. Use a demand and supply diagram to show the impact of the higher price of natural gas on the market for home heating oil.
