Answer to Question 1

A

Answer to Question 2

A change in demand occurs when consumers will buy more or less of a product at every price; a change in the quantity demanded occurs when the price changes and consumers buy more or less. A change in demand is reflected by a shift of the entire demand curve, while a change in the quantity demanded is reflected by a movement along one demand curve.
Only a change in the price of the good brings about a change in the quantity demanded. A change in demand is brought about by a change in any of the other influences on demand, namely, the prices of related goods, income, expectations, the number of buyers, and preferences.
