Question

which factor has helped cities like riyadh and doha grow into global economic hubs in the modern era?

○ access to vast natural resources, particularly oil

○ the rise of agriculture

○ geographic isolation from the rest of the world

○ the decline of trade routes

Explanation:

Riyadh (Saudi Arabia) and Doha (Qatar) are in the Middle East, a region rich in oil reserves. Access to vast oil resources has driven their economic growth, enabling infrastructure, trade, and investment. The rise of agriculture is not a key factor here (these regions have arid climates). Geographic isolation and decline of trade routes would hinder, not help, economic hub growth.

Answer:

A. Access to vast natural resources, particularly oil
