[求助]崩溃，这是为什么，请高手指点？

T-3-Q13.

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.

参考答案是E。一点都搞不明白，怎么会是E呢。请高手指点，谢谢

the passage refers that traditional treatment will normally cost 7 days, while people always take only 3 days - that resulted in the higher reinfection. But even though higher reinfection could happen, then why people still take only 3 days? If the case is E, it will e unnecessary to take the new treatment for 3 days, and the reinfection will be less common.

还不是很明白，文章说如果用后一种药将比前一种药减少复发。

问下边那个加强？

E说两种药用了三天都好了。为什么就加强了？

Therefore, reinfection will probably be less common in cases where the new antibiotic is prescribed

这是结论，

E说复发减少因为人们都是3天后就不用药了，（刚好这药就是3天见效，文中），支持了结论

我觉得这题排除比较好，E感觉就是重复了前提many patients stop taking those drugs within three days

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

无论什么药，大多数病人在吃药后三天感觉康复了，其实还没有康复。一旦病人感觉康复后，他们会停止吃药，从而导致复发。

所以如果新药能在在三天治好病人，就不存在上述问题，就可以减少复发。

en,5楼的解释已经比较清楚了，偶再补充说明一下：

1，老药的规定服用时间是7天，但是服用3天后病人会感觉已经康复，所以停止吃药，但实际上没有康复，所以导致复发

2，新药的规定服用时间是3天，但如果病人服用1天或2天后就感觉康复也停止吃药的话，也会导致复发，如果是这样的话，新药售卖区域的复发率不一定比老药低。所以，强调新药在服用3天后病人才会康复并且感觉到康复，这样复发率才会真正减低。

所以e能够加强结论的得出。

嗯 补充得很全面
