one advantage of international trade is that

Step 1: Analyze the question The question asks for an advantage of international trade, which is the exchange of goods and services between countries.

Step 2: Explain the concept Countries differ in climate, natural resources, labour skills and technology. No country can efficiently produce everything its people want. International trade lets countries specialize in what they produce best (comparative advantage) and exchange the surplus. The main benefits are:

• Access to a wider variety of goods and services
• Larger markets for a country's exports
• Efficient use of resources through specialization
• Lower prices and greater competition
• Transfer of technology and ideas

Step 3: Evaluate each option

• A. Prices of goods become stable. This is wrong. International trade exposes a country to world price changes, such as swings in the price of crude oil or cocoa, and exchange rate fluctuations. This can make prices less stable.
• B. Countries become self-sufficient. This is wrong. Trade creates interdependence. A self-sufficient country has no need to trade.
• C. Goods consumed are produced at a very high cost. This is wrong. It is the opposite of an advantage. Trade lets countries get goods at lower cost by buying from the most efficient producers.
• D. It makes possible the consumption of a variety of goods. This is correct. Nigerians can enjoy goods such as cars, machinery or wheat that are not produced locally or are produced only in small quantities, while other countries buy Nigerian crude oil, cocoa and so on.

Step 4: Answer

Exam tip: When you see "advantage of international trade," look for keywords like variety, specialization, larger market, wider choice, efficient use of resources. Be wary of options with "self-sufficient" or "stable prices," because trade does the opposite (interdependence, price fluctuations).
