23. Near Chicago a newly built hydroponic spinach “factory,” a completely controlled environment for growing
spinach, produces on 1 acre of floor space what it takes 100 acres of fields to produce. Expenses, especially
for electricity, are high, however, and the spinach produced costs about four times as much as washed
California field spinach, the spinach commonly sold throughout the United States.
Which of the following, if true, best supports a projection that the spinach-growing facility near Chicago will be
profitable?
(A) Once the operators of the facility are experienced, they will be able to cut operating expenses by about
25 percent.
(B) There is virtually no scope for any further reduction in the cost per pound for California field spinach.
(C) Unlike washed field spinach, the hydroponically grown spinach is untainted by any pesticides or herbicides
and thus will sell at exceptionally high prices to such customers as health food restaurants.
(D) Since spinach is a crop that ships relatively well, the market for the hydroponically grown spinach is no
more limited to the Chicago area than the market for California field spinach is to California.
(E) A second hydroponic facility is being built in Canada, taking advantage of inexpensive electricity and high
vegetable prices.



选C  

我想问的是produces on 1 acre of floor space what it takes 100 acres of fields to produce
这句话是神马意思。。。

求大神给个逻辑链 谢谢

芝加哥的水培工厂产量高，一个单位面积的产量是普通100个单位面积的产量，但是费用过高，4倍于加州的水浇地，加强：芝加哥的工厂能赚钱（P=R-C，要profit高，cost也高，所以revenue必须高）
A：成本降低25%不够（4倍于）
B: 加州的无关
C：P=R+C，Revenue高
D：市场范围与revenue or profit无关
E：看到second就错

谢谢 我懂了  刚开始我理解的和您翻译的是一样的 不过一想  这都100倍的产量了不加强都够了啊。。然后 。。。然后 就晕了  原来这么简单

这里不存在降25%够不够的问题吧。。题目说比加州的高4倍，要profit是和自己的cost比较啊
