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?

 

1. Whether zinc is effective only against colds, or also has an effect on other virally caused diseases
2. Whether there are remedies that do not contain zinc but that, when taken orally, can reduce the duration of colds
3. Whether people who frequently catch colds have a zinc deficiency
4. Whether either the zinc gel or the lozenges contain ingredients that have an impact on the activity of the zinc
                       
5. Whether the zinc gel has an effect on the severity of cold symptoms, as well as on their duration

   Answer: D

  我选B 原文结论的焦点明明是 nose 和 mouth 嘛

lozenge和gel都含锌，但是治疗感冒效果不同→推出结论：原因是使用部位不同

D选项：回答是的话，有其他物质存在，部位不同可能不是唯一原因——他因削弱；回答否，则排除他因削弱的可能性——加强

B选项没有评价（加强或削弱）的作用

B选项可以阿 假如有这种药品存在，也就是说口服也能有效，那证明不是mouth与nose的问题，正是削弱结论阿

原文争论的焦点在于mouth与nose 而D根本就没有提及

 I think B is reasonable. I will come back on that.

D應該沒錯 因為比較的標的是兩者都含Zn 為什麼其中一個比較有效  gel (鼻用) lozenges(口服)

I think choice D is correct because it still focus on zinc gel and the lozenges.

Choice B 有點出題了 因為討論另一種不含zinc 的藥物. 所以沒辦法有效的評斷文章的結論.

參考看看.

vote for D. option B  only weaken the conclusion but it cannot strenghthen the conclusion, so it cannot be the answer.

Different ways of adimistration of the drug leads to the judgement of virous location in whether nose or mouse.

I stand with B. If the answer is yes, it will weaken the the conclusion says that the virous's location is in the nose since taken orally, the other durgs that used to treat cold still have the effect. So we can't made a judgment on the location of virous through the effectiveness of certain durg mentioned in the argument.

In D, I think it is used to certify whether it is the zinc that something could treat the cold. I think it is not the point of the conclusion. It can be used to specify that activated Zinc is the key to the treatment of cold and that's all. But what about the location of the virous which is clearly stated in the conclusion ? No answers at all.

I stand with D.

B looks like a correct answer. However, it focuses on the indegrent zinc i/o the location where the gel or lozenge is applied.

D if the answer is yes, then the argument will be weakened; if no, strengened.
