Final answer:
If Chile has a comparative advantage in the production of copper, it should focus on copper production.
Step-by-step explanation:
In this scenario, if Chile has a comparative advantage in the production of copper, it should focus on copper production. Comparative advantage refers to the ability of a country to produce a good at a lower opportunity cost than another country. Since Chile has a comparative advantage in copper, it means that Chile can produce copper at a lower opportunity cost compared to Argentina. Therefore, Chile should focus on copper production and trade with Argentina for wheat, where Argentina has an absolute advantage.
