4.     In stating the argument, the author does which one of the following?

(A) makes a detailed statistical projection of future topsoil loss

(B) makes a generalization about total reduction in topsoil depth in all states

(C) assumes that the United States government does not place a high value on its natural resources

(D) refrains from using slanted language concerning the level of federal expenditures（E）

(E) compares state expenditures with federal expenditures

好像整个句子 makes a generalization about total reduction in topsoil depth in all states 的情况比较多吧.比如: In the United States, each bushel of corn produced might result in the loss of as much as two bushels of topsoil. Moreover, in the last 100 years, the topsoil in many states, which once was about fourteen inches thick, has been eroded to only six or eight inches.

)compares state expenditures with federal expenditures 只是最后一句提到的啊

为什么不选B 啊?

sorry , forgot the text.

The United States government generally tries to protect valuable natural resources. But one resource has been ignored for too long. In the United States, each bushel of corn produced might result in the loss of as much as two bushels of topsoil. Moreover, in the last 100 years, the topsoil in many states, which once was about fourteen inches thick, has been eroded to only six or eight inches. Nonetheless, federal expenditures for nationwide soil conservation programs have remained at ridiculously low levels. Total federal expenditures for nationwide soil conservation programs have been less than the allocations of some individual states.

NN,pls let us know the reason.

I understand it. thanks !

还没人回答么？我也奇怪D……

Because there has been a great plunge in the depth of top soil in many states.

And the federal government has put less money in soil conservation than some individul states have.

So, soil has not been regarded as a valuable natural resource by the federal gov.

Where is the generalisation?
