Plant scientists have been able to genetically engineer vegetable seeds to produce crops that are highly resistant to insect damage. Although these seeds currently cost more than conventional seeds, their cost is likely to decline. Moreover, farmers planting them can use far less pesticide, and most consumers prefer vegetables grown with less pesticide, therefore, for crops for which these seeds can be developed, their use is likely to become the norm.
which of the following would be most useful to know in evaluating the argument above?
Whether plant scientists have developed insect-resistant seeds for every crop that is currently grown commercially
Whether farmers typically use agricultural pesticides in larger amounts than is necessary to prevent crop damage.
Whether plants grown from the new genetically engineered seeds can be kept completely free of insect damage.
Whether seeds genetically engineered to produce insect-resistant crops generate significantly lower per acre crop yields than do currently used seeds.
Whether most varieties of crops currently grown commercially have greater natural resistance to insect damage than did similar varieties in the past.
评价题正方向加强，反方向削弱，这道题说的是有一种新的农作物可以抗虫，说了两个好处，第一，它虽然贵，但是成本低； 第二，农民可以少用杀虫剂，并且消费者喜欢没有杀虫剂的农作物。所以得出的结论是，这种农作物今后会成为种植的标准。
评价题是考察作为决策者的决策能力。作为公司的决策者，对于项目是否执行有着决策权，提出的问题需要一针见血，关系到公司的利益，使好的项目可以通过，不好的项目可以被否决。
而这道题，它虽然成本低，而且消费者喜欢，但是没有考虑的是它的产量，也就是说，要是产量很低，就算消费者再喜欢，成本再低，市面上很难出现这种农作物，也不可能让它develop，所以选D，
而B选项，不管农民用的杀虫剂的量是多还是少，完全不会影响结论它到底会不会develop
