Answer:
To obtain products they cannot make themselves
Step-by-step explanation:
Nations trade with each other primarily to obtain products or goods that they cannot produce or manufacture themselves. This is because different nations have different resources, skills, and capabilities, and through trade, they can exchange goods and services to meet their respective needs and wants. For example, a country that lacks certain natural resources may choose to import those resources from another country through trade. International trade allows nations to specialize in the production of goods and services in which they have a comparative advantage, and it promotes economic interdependence and cooperation among nations. The other options provided, such as stopping workers from coming to a nation, limiting the economic power of governments, or gaining control of another nation's government, do not accurately explain the primary reasons for international trade between nations.
