Which means of transport was crucial for crossing arid regions along the Silk Road?

• A. Silk Road
• B. Camel Caravans
• C. Cultural Exchange
• D. Paper money

Answer: (B)

The main idea being tested is what kind of transport made it possible to move goods across the Silk Road’s desert sections. Camels were ideal for crossing arid regions because they can go long distances with little water, endure intense heat, and carry heavy loads. These traits let merchants travel in camel caravans, a string of loaded animals that could survive the harsh desert terrain, provide mutual support, and enable safe, relatively predictable trade routes. This way, silk, spices, and other valuables could travel across vast desert stretches between regions. The other options describe the route, the outcomes of exchange, or a form of money, none of which describe a transport method, so they don’t fit as the way goods actually crossed the deserts.
