Why is agricultural production in China distributed in this way?

Question

A.
Much of western China is covered by dense rain forests.

B.
Much of western China is mountainous and has a desert climate.

C.
The Huang He frequently floods, destroying farmland in western China.

D.
The Gobi Desert covers western China, making it incapable of supporting farms.

Answer 1

B. Much of western China is mountainous and has a desert climate.

This geographical setting makes it difficult for agricultural production to thrive in western China, leading to a more concentrated distribution of agricultural production in other regions of the country.
