Which statement best describes the Grand Canal's purpose?

• A. Used mainly for defense against nomads
• B. Linked Silk Road with river systems
• C. Linked Yellow River region to the Yangtze basin
• D. Provided water for agriculture in the north

Answer: (C)

Moving bulk goods, especially grain, between north and south China is the central idea behind the Grand Canal. By joining the Yellow River region in the north with the Yangtze basin in the south, the canal created a vital inland route for provisioning the capital and military garrisons. This integration made it possible to transport large quantities of rice and other staples to northern centers, supporting centralized governance across a vast empire and enabling rapid mobilization during campaigns. While the canal supported trade and development, its defining function was internal logistics that knit northern and southern regions together, rather than defense, the Silk Road, or irrigation alone. That is why linking the Yellow River region to the Yangtze basin best describes its purpose.
