标题: [求助]GWD-TN-11-13答案有疑问
The traditional treatment of strep infections has been a seven-day course of antibiotics, either penicillin or erythromycin. However, since many patients stop taking those drugs within three days, reinfection is common in cases where these drugs are prescribed. A new antibiotic requires only a three-day course of treatment. Therefore, reinfection will probably be less common in cases where the new antibiotic is prescribed than in cases where either penicillin or erythromycin is prescribed.

Which of the following, if true, most strengthens the argument?

A. Some of people who are allergic to penicillin are likely to be allergic to the new antibiotic.

B. A course of treatment with the new antibiotic costs about the same as a course of treatment with either penicillin or erythromycin.

C. The new antibiotic has been shown to be effective in eradicating bacterial infections other than strep.

D. Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections

E. Regardless of whether they take a traditional antibiotic or the new one, most patients feel fully recovered after taking the drug for three days.

答案选E，我选B。题目的结论是新旧两种antibiotics的对reinfection效果的比较，答案E显然抹杀了二者的区别，怎么会选它？选B的原因是，因为两种治疗的成本差不多，新药又比旧药更短时间（3天）内治愈，避免患者停止用药，所以支持了结论reinfection will probably be less common in cases where the new antibiotic is prescribed than in cases where either penicillin or erythromycin is prescribed

所以应该选B

听听NN们的意见啊！！

这道题已经讨论过了，lz搜一下老帖子吧。

B按lz的解释有一些道理的样子，但是这个支持的力度是很弱的。首先，成本不是一个加强的因素，特别是这个新的方案只是和老方案的价格一样而不是更低，最多只能说B不是削弱但无法说他是加强。

E选项的逻辑是非常加强论点的，原因很简单，患者停止用药的原因就是他们感觉自己已经康复了，但是老方案的“康复”只是一种错觉，而新方案则是真的康复，所以新方案不会误导患者在康复前就停止用药。从而得出新方案比老方案好。
