Answer: the combinations of two goods that can be produced with society's available resources
Explanation:
The production possibility curve is a curve that shows the maximum amount of two goods that can be combined in an economy using the country's available resources.
An outward shift of the production possibility curve or rightward shift implies that there's economic growth in the economy. This could be as a result of advancement in technology or better trained workers. An inward or leftward shift means lesser goods are produced in the economy. This could be as a result of war or other negative happenings.
