Certain genetically modified strains of maize produce a powerful natural insecticide. The insecticide occurs throughout the plant, including its pollen. Maize pollen is dispersed by the wind and frequently blows onto milkweed plants that grow near maize fields. Caterpillars of monarch butterflies feed exclusively on milkweed leaves. When these caterpillars are fed milkweed leaves dusted with pollen from modified maize plants, they die. Therefore, by using genetically modified maize, farmers put monarch butterflies at risk.
Which of the following would it be most useful to determine in order to evaluate the argument?
Whether the natural insecticide is as effective against maize-eating insects as commercial insecticides typically used on maize are
Whether the pollen of genetically modified maize contains as much insecticide as other parts of these plants
Whether monarch butterfly caterpillars are actively feeding during the part of the growing season when maize is releasing pollen
Whether insects that feed on genetically modified maize plants are likely to be killed by insecticide from the plant's pollen
Whether any maize-eating insects compete with monarch caterpillars for the leaves of milkweed plants growing near maize fields
不是很懂，文章的信息以已近暗含了毛毛虫会吃花粉了啊，为什么还要再强调一遍毛毛虫吃花粉这件事？
笔记：好题记录。其他项要么无关，要么无法直接地评估
D说的是害虫insects吃到会不会死，原文已经说了caterpillar吃了就会死
B 同E 关注的是毛毛虫能不能吃到带花粉的叶子，而不是吃多少
C 有时间差，毛毛虫吃的叶子可能根本没有花粉
strains of 种族 种类
Gap 用了转基因玉米 ≠ 毛毛虫会吃到带花粉的叶子
因果推理, 找反驳结论(果)选项, (C) CQ2：因果联系问题
因果推理吗？
选错成B。ccurs throughout the plant, 所以B错啦
