5. Consider two points on the PPF: point A, at which there are 10 apples and 20 pears, and point B, at which there are 7 apples and 21 pears. If the economy is currently at point A, the opportunity cost of moving to point B is
a. 1 pear.
b. 7 apples.
c. 3 apples.
d. 21 pears.
6. The PPF between goods X and Y will be a downward-sloping
a. straight line if increasing opportunity costs exist.
b. straight line if decreasing opportunity costs exist.
c. curve that is bowed outward if increasing opportunity costs exist.
d. curve that is bowed outward if constant opportunity costs exist.
7. Efficiency implies that
a. it is impossible to obtain gains in one area without losses in another.
b. it is possible to obtain gains in one area without losses in another.
c. there are too many resources.
d. there are too few resources.

12. If the demand curve for a good shifts leftward,

b. quantity demanded remains constant at each price.
c. quantity demanded is greater at each price.
d. demand is greater at each price.

15. At a price above equilibrium price, there is
a. a shortage.
b. a surplus.
c. excess demand.
e. none of the above
16. On a supply-and-demand diagram, quantity demanded equals quantity supplied
a. only at the single equilibrium price.
