B) Compare the marginal benefits and marginal costs of their available options.
C) Avoid making any decisions that involve risk or uncertainty.

9. A city decides to build a new public park on a vacant lot. Which of the following
represents the opportunity cost of this decision?
A) The total cost of constructing the park and its ongoing maintenance.
B) The value of the housing or commercial development that could have been
built on that lot.
C) The increase in property values for homes located near the new park.
D) The number of visitors the park is expected to attract each year.

that is forgone.
10. Which of the following statements about the factors of production is most
accurate?
A) Money is considered the most important factor of production in modern
economies.
B) Entrepreneurship involves combining the other factors of production to

and capital to produce goods and services.
11. A society that is producing at a point inside its production possibility frontier is
best described as operating in which of the following conditions?
A) With maximum efficiency in the use of all its resources.
B) With some resources that are unemployed or underemployed.
C) At a level of production that is currently unattainable.
D) With a level of technology that is superior to other societies.
Rationale: A point inside the PPF indicates that the economy is not fully utilizing
all of its available resources or is not using the best available technology.
12. The law of increasing opportunity cost, which gives the PPF its bowed-out
shape, is primarily explained by which of the following?
A) The fact that all resources are equally suited to producing all goods.
B) The fact that resources are not perfectly adaptable to alternative uses.
C) The assumption that technology never changes in an economy.
D) The idea that consumers always prefer more of every good.
Rationale: As production of a good increases, resources less suited to its
production must be used, raising the opportunity cost of additional units.
13. Which of the following events would cause an economy's production
possibility frontier to shift outward?
A) A reduction in the size of the labor force due to emigration.
B) A technological breakthrough that improves manufacturing productivity.
C) The decision to produce more of one good and less of another.
D) A decrease in the amount of capital available for production.
Rationale: Economic growth, often driven by technological advancement, shifts
the PPF outward, allowing more of all goods to be produced.
14. A point lying outside a nation's current production possibility frontier is best
characterized as which of the following?
A) A point of maximum efficiency in production.
B) A point that reflects unemployed resources.
