Asia leads global air travel by becoming the world's central hub for passenger flights. Which region is described?

• A. Europe
• B. Asia
• C. Africa
• D. North America

Answer: (D)

A central hub for passenger flights means a region where many flight routes meet and a large share of global travelers pass through its airports. If Asia is described as leading global air travel, that points to Asia as the region being described, because the statement assigns the hub status to that region.

Think of Asia hosting major transfer airports—Changi in Singapore, Haneda and Narita in Tokyo, Incheon in Seoul, Hong Kong, Shanghai and Beijing in China, among others. These hubs connect a vast web of international and domestic routes, creating a dense network flow. The rapid growth of air travel across Asia-Pacific, plus expanding airport capacity and new routes in places like China, India, and Southeast Asia, strengthens Asia’s central role in global air travel.

So the region described by the statement is Asia.
