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?
Most of the vegetation to be placed around the ponds is native to Nufa.
Fish raised on PhishCo's farms are likely to be saleable in the nearest urban areas.
Organic waste from fish in the pond water will help to fertilize fields where it is used for irrigation.
The government of Nufa will help to arrange loan financing to partially cover the costs of drilling.
Ponds will be located on low-lying land now partially occupied by grain crops.
选项剩下C和E，E是说池塘会在现在种crop的地方建立，可能是要挖走crop建，就不是increase the total production
选项C更直接有效的废物利用来increase production
目标：increase the farms' total production。与目标无关的选项一律错。1，2，4，5都没有办法增加产量。1植物是否native 无否得知产量变化。2鱼能否被卖掉和产量无关。4是财务问题跟产量无关。5反而是有点削弱，pond 占用了可以种粮食的产地。
