40. GWD-23-Q14
Plantings of cotton bioengineered to produce its owninsecticide against bollworms, a major cause of crop failure, sustained littlebollworm damage until this year. Thisyear the plantings are being seriously damaged by bollworms. Bollworms, however, are not necessarilydeveloping resistance to the cotton’s insecticide. Bollworms breed on corn, and last year morecorn than usual was planted throughout cotton-growing regions. So it is likely that the cotton is simplybeing overwhelmed by corn-bred bollworms.
In evaluating the argument, which of the following wouldbe most useful to establish?
A. Whether corn could be bioengineered toproduce the insecticide
B.Whetherplantings of cotton that does not produce the insecticide are sufferingunusually extensive damage from bollworms this year（correct）
C. Whether other crops that have beenbioengineered to produce their own insecticide successfully resist the pestsagainst which the insecticide was to protect them
D. Whether plantings of bioengineered cottonare frequently damaged by insect pests other than bollworms
E. Whether there are insecticides that can beused against bollworms that have developed resistance to the insecticideproduced by the bioengineered cotton
木有理解啊，为什么选B呢？一会儿cotton一会儿corn，都被搅晕了~~求清醒的人解释一下~
谢谢！！！
