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? ['Organic waste from fish in the pond water will help to fertilize fields where it is used for irrigation.', "Fish raised on PhishCo's farms are likely to be saleable in the nearest urban areas.", 'Ponds will be located on low-lying land now partially occupied by grain crops.', 'The government of Nufa will help to arrange loan financing to partially cover the costs of drilling.']
