问题 PhishCo runs a number of farms in the arid province of Nufa, depending largely on irrigation. Now, as part of a plan to efficiently increase the farms’ total production, it plans to drill down to an aquifer containing warm, slightly salty water that will be used to raise fish in ponds. The water from the ponds will later be used to supplement piped-in irrigation water for PhishCo’s vegetable fields, and the ponds and accompanying vegetation should help reduce the heat in the area of the farms.
Which of the following would, if true, most strongly suggest that the plan, if implemented, would increase the overall efficiency of PhishCo’s farms?

选项 A、Most of the vegetation to be placed around the ponds is native to Nufa.
B、Fish raised on PhishCo’s farms are likely to be saleable in the nearest urban areas.
C、Organic waste from fish in the pond water will help to fertilize fields where it is used for irrigation.
D、The government of Nufa will help to arrange loan financing to partially cover the costs of drilling.
E、Ponds will be located on low-lying land now partially occupied by grain crops.

答案 C

解析 Evaluation of a Plan
Situation A company plans to increase the total efficiency of its farms in an arid region by drilling down to an aquifer whose water will be used to raise fish in ponds and to help irrigate the farms’ vegetable fields. The ponds and accompanying vegetation should help reduce the heat around the farms.
Reasoning What would make it most likely that implementing the plan would increase the farms’ overall efficiency? The farms will become more efficient if the plan significantly increases their production for little or no added cost.
A Vegetation native to an arid region may be no more likely to thrive around ponds than non-native vegetation would be, and in any case would not clearly increase the farms’ total crop production or efficiency.
B This makes it slightly more likely that the plan would increase the farms’ profitability, not their efficiency or productivity.
C Correct. Fertilizing the fields with the waste while irrigating the crops might significantly improve crop production. But it would cost little or nothing extra, since the waste would already be in the irrigation water. Thus, this feature of the plan would likely enhance the farms’efficiency by increasing their productivity for no significant extra cost.
D This government assistance might slightly reduce the work the company has to do to procure a loan. But probably it would neither increase the farms’ production nor reduce the overall expense of implementing the plan (including the expense incurred by the government).
E If anything, this suggests that the plan might reduce the farms’ efficiency by eliminating productive crop land.
The correct answer is C.
