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. 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） compares state expenditures with federal expenditures
