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?

正确答案: D

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?

AWhether plant scientists have developed insect-resistant seeds For every crop that is currently grown commercially
BWhether farmers typically use agricultural pesticides in larger Amounts than is necessary to prevent crop damage.
CWhether plants grown from the new genetically engineered seeds Can be kept completely free of insect damage.
DWhether seeds genetically engineered to produce insect-resistant crops generate significantly lower per acre crop yields than do currently used seeds.
EWhether most varieties of crops currently grown commercially have Greater natural resistance to insect damage than did similar vari-eties in the past.

D正确
这是OG上一道题的变种题,那道题是问削弱,正确选项是B。但这道题是问评价,B只能给负评价,不能给正评价。

B选项应该是irrelevant, "typically use agriculture pesticide" 没说是对genetic seeds使用,还是对conventional seeds.

D。B选项与题目要求无关,无论农民是否用了“过量"的农药,农药的实际使用量都大幅下降了,并且吸引了消费者。这些已经可以满足判断的条件了,是否可以再减少农药的使用量最多影响吸引消费者的程度,但并不改变已经可以吸引大量消费市的事实。

OG的原题跟本题不是一个目的,
本题D,B是无关选项,重点是结合问题。

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

D 选项我感觉不好
1. 根本没有说产量高了就普及,产量低了就不能普及。原文都没说这个标准,原文只是讨论cost 和 消费者对于少打农药的偏爱对于普及的影响,所以D 无关选项
2. 而且d选项就算有关,还有个问题,你说市面上很难流通这个产品?但是这个东西赚钱,我种个1w亩,照样可以啊。d只说的是每亩的产量,不代表最后产量

D 要去替代现有的seed,那么需要保证产量不下降才有意义
