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 it be most useful to establish?

正确答案: B

gwd 21-14, 求助各位NN一道题

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 it be most useful to establish?

 

  1. Whether corn could be bioengineered to produce the insecticide

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

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

  4. Whether plantings of bioengineered cotton are frequently damaged by insect pests other than bollworms
  5. Whether there are insecticides that can be used against bollworms that have developed resistance to the insecticide produced by the bioengineered cotton

请教各位GGJJ,这题为什么是B,小妹觉得B和这到题一点联系都没有,very confused

感谢斑竹,这题是gwd 21-14.

还有一个问题想请问斑竹,gwd的题和实际考试题比起来是不是偏难阿?感觉至少逻辑和语法要比OG难很多

真考高分题就是GWD的难度. OG主要是用来练思路和技巧的.

B是对的,如果normal的cotton受灾比以往更严重的话,那就支持了结论。

D无关,问的是ballworm和cotton的关系,其他的insects不在问题考虑中。

感谢caterpillarcn的解释,这种难度的题如果考试考到的话估计小妹我是错不对的。

还像想问wycg一个问题,你所说的真考高分题就是gwd的难度,但是像这种难度的gwd题在真考中也就只占一定的比重把?真考中不是所有的题都和gwd上的难度一样把?
