Which statement best describes global interdependence?

• A. Nations rely on each other for goods, services, and capital
• B. A single country can produce everything it needs without imports
• C. International organizations never affect national economies
• D. A country should isolate its economy from others

Answer: (A)

Global interdependence is the mutual reliance of nations on each other for goods, services, and capital, made possible by trade, investment, and the exchange of ideas and technology. Because countries specialize in what they produce most efficiently, they rely on imports for other goods and on foreign capital to fund development, research, and infrastructure. This creates a web of connections—think how oil, electronics, and medicines move across borders and how foreign investment funds projects at home. Global markets and supply chains link economies, so events in one place can ripple through prices and availability worldwide.

The statement that nations rely on each other for goods, services, and capital best describes this idea. The notion that a country could produce everything it needs without imports ignores resource limits and the benefits of specialization. The view that international organizations never affect national economies is incorrect, since institutions shape trade rules, lending, and policy. And isolating an economy runs counter to how global markets actually operate.
