Final answer:
A trading possibilities line is the graphic that shows the amounts of two products a nation can acquire by specializing in one product and trading for the other, which is illustrated using the production possibilities curve.
Step-by-step explanation:
The type of graphic that shows the amounts of two products a nation can obtain by specializing in one product and trading for the other is known as a trading possibilities line. This line represents how a country can benefit by producing the goods for which it has a comparative advantage and then trading for the other goods it requires. The production possibilities curve helps to visualize the trade-offs and potential gains from specialization and trade. By engaging in trade, a nation can consume beyond its own production possibilities curve, reflecting the economic principle of comparative advantage.
