Classify each statement as true or false by dragging it into the corresponding category. When 2 countries choose to partake in international trade, it is a mutually beneficial activity for both countries. Through specialization and trade it is possible for a country to consume a combination of goods that is beyond its original production possibilities frontier. Wealthier countries always benefit more from international trade than poorer countries. Countries trade for goods in which they do not have a comparative advantage, and therefore, would never trade with nations that have similar resource endowments.
