两题都是evaluation 1. GWD-23-Q14 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 ANS: B 这题我不是很懂题目的思路耶...我看CD上的争议是B和C 不过我选了D... = =||| 2. GWD-29-Q27 Though sucking zinc lozenges has been promoted as a treatment for the common cold, research has revealed no consistent effect. Recently, however, a zinc gel applied nasally has been shown to greatly reduce the duration of colds. Since the gel contains zinc in the same form and concentration as the lozenges, the greater effectiveness of the gel must be due to the fact that cold viruses tend to concentrate in the nose, not the mouth. In order to evaluate the argument, it would be most helpful to determine which of the following? A. Whether zinc is effective only against colds, or also has an effect on other virally caused diseases B. Whether there are remedies that do not contain zinc but that, when taken orally, can reduce the duration of colds C. Whether people who frequently catch colds have a zinc deficiency D. Whether either the zinc gel or the lozenges contain ingredients that have an impact on the activity of the zinc E. Whether the zinc gel has an effect on the severity of cold symptoms, as well as on their duration ANS: D 这题我选B耶 CD上这题是在争B和D 虽然大部份的人觉得是D 但我还是不懂为什麽D比较好~ 先谢谢回答罗~~ --
