Answer:
b. the economy cannot produce more of one good without giving up the production of another good.
Explanation:
The production possibility curve shows the two combinations of goods an economy can produce when all its resocurces are fully employed.
When production is taking place on a point on the production possibility curve, it means that production is efficient and all the resources are fully employed. It shows that the economy cannot produce more of one good without giving up the production of another good.
Points inside the production possibility curve shows that production is inefficient; all resources in the economy aren't fully employed.
Points outside the production possibility curve are unattainable given the resources of the economy.
When technological change occurs, the curve shifts outward.
