Scientists have made genetic modifications to cotton to increase its resistance to insect pests. According to farmers’ report, the amount of insecticide needed per acre to control insect pests was only slightly lower for those who tried the modified seed than for those who did not. Therefore, since the modified seed costs more than ordinary seed without producing yields of higher market value, switching to the modified seed would be unlikely to benefit most cotton farmers economically.

Which of the following would it be most useful to know in order to evaluate the argument?

A.Whether farmers who tried the modified cotton seed had ever tried growing other crops from genetically modified seed.

B.Whether the insecticides typically used on ordinary cotton tend to be more expensive than insecticides typically used on other crops.

C.Whether for most farms who grow cotton it is their primary crop

D.Whether the farmers who have tried the modified seed planted as many acres of cotton, on average, as farmers using the ordinary seed did.

E.Whether most of the farmers who tried the modified seed did so because they had previously had to use exceptionally large quantities of insecticide.

这是GWD11的第三题，答案是B，但是网上的争论是D和E，


我选的E，请教牛人这道题有没有定论了，是选D还是选E


呢，为什么！！！

我选B更好一些 比D和E更直接的说明了收益的问题和结论更密切一些

这个题和OG12-69很像，选的是E的内容项。B是错的因为B没有在ARGUMENT中出现。
我也选的E结果答案是B...

应该是E吧，GWD的答案不是完全正确的。。。
这里明显是需要考虑应用棉花地的大小可能对每公顷农药量存在的影响啊
B项other crops是扩大范围的无关选项吧。。。

这道题跟OG12--69很像。。
OG上明确说other crops是无关项

支持E

肯定不是d，文中说的是per acer的用量，选项说的只有面积没有用量。
肯定不是E，只有用量没有面积，怎么知道per acer的用量。
b绝对正确，因为原文最后是economically。b中是关于杀虫剂价钱的思考，所以是正确的。我经验来看，expensive这个词在英语中代表了一个price是否高低的概念。就像中文里的贵。逻辑而言，你说贵的时候通常都是带着unit的含义在其中，所以文中指出的expensive就是说per acer用量的贵贱。
我语文很差，理解万岁。。。。
（逻辑就是对量的理解，审题要仔细。）

B is right. It provides the ONLY information relevant to the COST comparison.

这题的题目跟OG12-69基本一样的，但是选项不同。选项的改变导致了E不再是正确选项，B是正确的。
