GMAT培训 每日一题-逻辑第68题
博智教育 GMAT培训 GMAT每日一题
Scientists have modified feed corn genetically, increasing its resistance to insect pests. Farmers who tried out the genetically modified corn last season applied less insecticide to their corn fields and still got yields comparable to those they would have gotten with ordinary corn. Ordinary corn seed, however, costs less, and what these farmers saved on insecticide rarely exceeded their extra costs for seed. Therefore, for most feed-corn farmers, switching to genetically modified seed would be unlikely to increase profits.
Which of the following would it be most useful to know in order to evaluate the argument?
(A) Whether there are insect pests that sometimes reduce feed-corn yields, but against which commonly used insecticides and the genetic modification are equally ineffective
(B)&Whether the price that farmers receive for feed corn has remained steady over the past few years
(C)&Whether the insecticides typically used on feed corn tend to be more expensive than insecticides typically used on other crops
(D)&Whether most of the farmers who tried the genetically modified corn last season applied more insecticide than was actually necessary
(E)&Whether, for most farmers who plant feed corn, it is their most profitable crop
题目分析：原文谈的是用新种子和延续用老种子哪个更省钱。A说有一种坏虫用杀虫剂和用新种子都没用。两种种子都没用和哪个更省钱有什么关系，杀。B说farmer挣得钱最近比较稳定，扯得就更远了，杀。C说用于corn的杀虫剂比用于其它谷物的贵，没说过用于其它谷物，范围错了，杀。D说如果那些用新种子的去年用老种子时用的杀虫剂会比较多，那不就费钱了嘛，没跑题，留着。E说corn是一种盈利的谷物，发表评价类的错误答案，杀。
