Question

the production possibilities curve shows that:
a. some of one good must be given up to get more of another good in an economy that is operating efficiently.
b. no output combination is impossible.
c. an economy that is operating efficiently can have more of one good without giving up some of another good.
d. scarcity can be eliminated.

Explanation:

The production possibilities curve (PPC) illustrates the trade-offs an economy faces due to scarce resources. On the PPC, points represent efficient production: to increase output of one good, resources must be shifted from the other, meaning some of the first good is sacrificed. Option b is wrong because combinations outside the PPC are impossible. Option c contradicts the concept of trade-offs on the efficient PPC. Option d is wrong because scarcity is the fundamental reason the PPC exists and cannot be eliminated.

Answer:

a. some of one good must be given up to get more of another good in an economy that is operating efficiently.
