GWD-23-Q14(答案是B,请NN来给看看，非常感谢)

Plantings of cotton bioengineered to produce its own insecticide against bollworms, a major cause of crop failure, sustained little bollworm damage until this year.
This year the plantings are being seriously damaged by bollworms.
Bollworms, however, are not necessarily developing resistance to the cotton’s insecticide.
Bollworms breed on corn, and last year more corn than usual was planted throughout cotton-growing regions.
So it is likely that the cotton is simply being overwhelmed by corn-bred bollworms.

In evaluating the argument, which of the following would be most useful to establish?

A.
Whether corn could be bioengineered to produce the insecticide

B.
Whether plantings of cotton that does not produce the insecticide are suffering unusually extensive damage from bollworms this year

C.
Whether other crops that have been bioengineered to produce their own insecticide successfully resist the pests against which the insecticide was to protect them

D.
Whether plantings of bioengineered cotton are frequently damaged by insect pests other than bollworms

E.
Whether there are insecticides that can be used against bollworms that have developed resistance to the insecticide produced by the bioengineered cotton

阅读没过关吧

这题读懂了题 没逻辑难度的

建议还是先搞懂阅读 不然再简单的逻辑 看不懂题目也是白搭

谁能帮忙翻译一下呀。我一点都没搞懂这几句话之间到底有什么逻辑关系。

同问……我更想知道在时间来不及的情况下如何做对逻辑……没时间好好读啊

好像还是没有解释清楚哎。。。顶一下~拜牛人们赶紧赐教，真的没看懂这

个题目要评估的是什么？？？

er,U should figure out there are two kinds of planting of cotton:
can produce its own insecticide against bollworms  / cannot produce
premise1lantings of cotton(can produce its own insecticide against
bollworms) sustained little bollworm damage until this year.  This
year the plantings are being seriously damaged by bollworms.
premise2: Bollworms, however, are not necessarily developing
resistance to the cotton’s insecticide.
premise3: Bollworms breed on corn, and last year more corn than usual
was planted throughout cotton-growing regions.
conclusion:  So it is likely that the cotton is simply being
overwhelmed by corn-bred bollworms.
premise简单说就是 the planting of cotton 今年受bollworms影响很厉害。
但是bollworm并没有完全形成对insecticide的抵抗力。同时corn今年种植特别
多，导致靠C生长的B也很多。
B：不能形成insecticide的planting of cotton有没有因为Bollworm遭灾
I will go with B :B clearly establishes that it is not just the
resistant cotton that are getting affected, and  supports the
overwhelm theory.
the conclusion talks about COTTON in general, whereas argument only
accounted for planting(bio...can produce insecticide）therefore, we
must know something about non-bio one(cannot produce) to evaluate the
conclusion. B does that.
