Final answer:
A production possibilities curve for an agrarian society shows the maximum combinations of wheat and radios it can produce.
If impacted by a pandemic with population loss, the curve would shift inward, representing reduced production capacity due to less labor.
Step-by-step explanation:
The production possibilities curve (PPC) is a graphical representation that shows the maximum number of different combinations of two goods that an economy can produce, given its technological capabilities and factor endowments.
To construct a PPC for an agrarian society that produces wheat and radios, we assume that the technology available and the quantities of factors of production (e.g., labor, land, capital, and materials) are fixed.
If this society were impacted by a global pandemic that significantly reduced its population, the PPC would shift inward.
This is because the supply of labor, which is a key factor of production, would decrease, thereby reducing the society's capacity to produce both wheat and radios. With fewer workers, the society could not produce as much as it could before the pandemic, which results in a smaller production capacity represented by the new inward PPC.
