标题: LSAT-1-1-10.求助＝狒狒135－58

求助Some people say that the scarcity of food is a function of the finite limits of the earth’s resources, coupled with a relentless rate of population growth. This analysis fails to recognize, however, that much of the world’s agricultural resources are used to feed livestock instead of people. In the United States, for example, almost one-half of the agricultural acreage is devoted to crops fed to livestock. A steer reduces twenty-one pounds of inexpensive grain to one pound of expensive meat. Thus, the scarcity of food is not merely a function of limited resources and population growth.

Which one of the following is an assumption that would allow the conclusion in the argument to be properly drawn?

(A) People prefer eating meat to eating grain.

(B) Meat is twenty-one times more expensive than grain.

(D) More than one-half of the agricultural acreage in the United States is devoted to crops fed to humans.（E）

(E) Growing crops for human consumption on the acreage currently devoted to crops for livestock will yield more food for more people.

我选E是觉得其他的不靠边但是我研究不明白希望大家帮我看看

将E取非: 如果把那些acreage currently devoted to crops for livestock种给人吃的庄稼, 但产不出更多的food (这里的比较是grains for human和meat比), 那还不如继续种crops for livestock.
