Which sequence best describes how a country benefits from comparative advantage?

• A. Countries export goods in which they have lower relative costs and import others.
• B. Countries produce everything themselves to avoid trade.
• C. Countries rely solely on government subsidies for trade.
• D. Countries trade only with neighboring nations.

Answer: (A)

Understanding comparative advantage means recognizing that a country benefits from specializing in the goods it can produce at lower opportunity costs than other countries, and then trading for the rest. When a nation exports products where its relative costs are the smallest and imports products that would be costly to produce domestically, resources are used more efficiently overall and both trading partners can consume more than they could without trade. This flow—exporting goods with lower relative costs and importing others—best captures how nations gain from trade through specialization. Other scenarios don’t reflect this idea. Producing everything domestically avoids trade but misses the efficiency gains from specialization. Relying on government subsidies distorts trade and doesn’t illustrate how costs and benefits determine who should produce what. Trading only with neighboring nations ignores the cost advantages that come from comparing relative production costs, which is the core reason trade can be beneficial regardless of distance.
