Compared with Tennessee River Basin, Murray Darling River Basin is prone to irrigation problems
A. Salinization of arid land B. decrease of runoff C. change of wetland ecological environment D. need to build water conservancy project
Why,

A
I don't think what you said upstairs is right. The question requires a comparison between the two. The Tennessee River basin also needs to build water conservancy projects. The United States spends a lot of money to build water conservancy projects in this basin, which shows that D should be wrong
The soil in the areas where the Murray Darling River Basin flows is rich in salt, and the precipitation in these areas is very small. A large amount of irrigation leads to the uplift of groundwater, which aggravates the soil salinization. This problem should not occur in Tiannaxi and the river basin
