instruction: Given this paragraph about history of China, what is the name of the river that nurtured China's civilization.
context: The history of the area now known as China has alternated between periods of prosperity, political unity, and peace and periods of war and statehood. The Yellow River nurtured China's civilization. Between eras of multiple kingdoms and warlordism, Chinese dynasties have ruled parts or all of China; in some eras control stretched as far as Xinjiang, Tibet and Inner Mongolia, as at present.

With thousands of years of continuous history, China is among the world's oldest civilizations and is regarded as one of the cradles of civilization.
