As soon as Kublai Khan, the Mongol ruler who founded the Yuan Dynasty, chose a site for his capital city, he realized that he needed a hydraulic engineer. He found one in Guo Shoujing. What did Kublai need Guo to do for the city of Beijing?

B). He needed Guo to design a way to route water to Beijing, which had no natural waterways nearby.

Explanation:

Guo Shouling is popularly recognized as the engineer who expanded the Grand Canal. This assisted in easy transportation of water to Beijing for irrigation and other purposes. Naturally, it was quite difficult to make a waterway to Beijing and hence, Kublai Khan wanted Guo to design a water system which could address the water associated problems of the people. Thus, a 30km channel was built beginning from Shenshan Mountain and ending towards Dadu by connecting the rivers which contributed significantly in the development of the city.
