In which country is it a common tradition to use a levee system to grow rice?
a. russiab. turkeyc. koread. china

The answer is china

The answer is china. The most logical reason why is because they're basically known for growing rice. On the more real reason why, the Chinese built the first drainage and irrigation systems at the lower sections of the Yellow River about 2600 to 2700 years ago. The levees were built much farther up the river, and served the purpose of preventing too much erosion from taking place upstream, which caused agricultural problems for the growing Chinese civilization. Without levee's, their crops were essentially screwed due to constant flooding.
