Based on the graph that shows the production possibilities curve for shoes and watermelons, the curve is able to explain choice, scarcity, and opportunity cost as explained below.
The Production Possibilities Curve (PPC) explains the different combinations of the quantities of two goods that can be produced in a country given the resources the country has.
This shows the concept of choice because the country is forced to choose between producing more of one good and less of the other, or vice versa based on their resources.
It also shows the concept of scarcity which explains what happens when there are limited resources. When resources are limited, people have to make choices over what they will produce instead of producing everything they want to.
The PPE curve also shows opportunity cost because people are either forced to give up additional units of shoes to produce more watermelons, or more units of watermelons to produce shoes.
