A city that functions as a service center of the world economy

• A. Urban hierarchy
• B. World city (global city)
• C. Annexation
• D. Primate city

Answer: (B)

This item looks at which city type serves as a service center for the world economy. A world city, also called a global city, is defined by its ability to coordinate and provide advanced services that support international economic activity. These services include finance, corporate management, legal and consulting services, as well as media, culture, and research institutions. World cities host major multinational company headquarters, global stock exchanges, international organizations, and major air and sea hubs, which together keep capital, information, and people moving around the globe. Because of that, they function as pivotal hubs in the global economy.

Urban hierarchy is a framework for classifying cities by size and function, not specifically about global influence. A primate city is the dominant city within a country, usually the largest and most influential domestically, but it does not necessarily extend its influence globally. Annexation is the process of legally incorporating territory into a city and is unrelated to a city’s role in the world economy.

So the city that functions as a service center of the world economy fits the idea of a world city. Examples include New York, London, Tokyo, and other major global hubs.
