Question

Quizplus · Accepted Answer

International trade is an important source of economic growth as it allows countries to specialize and focus on their comparative advantages, leading to increased efficiency and productivity. Reducing the level of international trade would actually hinder economic growth. The other options (increasing business investment, increasing research and development, and reducing barriers to financial aid for higher education) are all sources of economic growth as they lead to increased productivity and innovation.
