Why do nations trade?

• A. Resources are distributed evenly across the world.
• B. No country has all the resources it needs to survive and grow.
• C. Trade is only driven by cultural exchange.
• D. All countries have identical resources.

Answer: (B)

Nations trade because no country has all the resources it needs to produce everything its people want or to grow its economy. Different places have different resources—some have abundant energy or minerals, others have fertile land, skilled labor, or advanced technology. By specializing in what they can produce efficiently and trading for the rest, countries get access to a wider variety of goods at lower costs. This idea is tied to the idea of comparative advantage: even if one country is good at many things, it gains by focusing on what it’s relatively best at and trading for the rest. That’s why the statement about not having all resources fits best. It reflects the reality that resources aren’t evenly distributed or complete everywhere. The other notions—resources distributed evenly, trade driven only by cultural exchange, or all countries having identical resources—don’t explain why trade actually happens in economies.
