问费费逻辑58题~给出的解释是不是有问题啊。。。感觉完全理解反了。

58. Some people say that the scarcity of food is afunction of the finite limits of the earth’s resources, coupled with arelentless rate of population growth. This analysis fails to recognize,however, that much of the world’s agricultural resources are used to feedlivestock instead of people. In the United States, for example, almost one-halfof the agricultural acreage is devoted to crops fed to livestock. A steerreduces 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 andpopulation growth.

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

A.     Peopleprefer eating meat to eating grain.

B.     Meatis twenty-one times more expensive than grain.

C.     Thelimits of the earth’s agricultural resources are not finite.

D.     Morethan one-half of the agricultural acreage in the United States is devoted todrops fed to humans.

E.     Growingcrops for human consumption on the acreage currently devoted to crops forlivestock will yield more food for more people.
