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 those 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 the 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.

答案为E   个人认为这个答案不够成对新药的支持啊，而其他选项也不合理，请问该怎么理解此题呢？谢谢！

大概题意：一种病一般是用7天的antibiotics去治疗的 antibiotics包括penicillin 或者 erythromycin。可是很多病人三天后就停止用药了，引起了再次感染，所以这些antibiotics会引起感染的。一种新的antibiotics只需三天的治疗，所以再次感染将会比用penicillin 或者 erythromycin少一些。

E说的是 大部分病人用药三天之后就会感到痊愈 所以这就是为什么他们会停药 那既然新药三天就真的有效 病人三天停药不仅会感到痊愈 而且会真正的痊愈。

我觉得是这样的吧
E里面说的是feel fully recovered
用新药的话在三天的时候不仅觉得自己好了实际也好了
所以不会有reinfection
但是如果旧药的话实际没好
会有reinfection
所以是加强结论说用新药的reinfection会比用旧药的少~

明白了，谢谢指点哦！

E说不管吃旧药新药，多数病人吃三天就觉得好了。言下之意就是多数吃三天就不吃啦，（因此那些吃的是新药的病就好了，吃的是旧药的就可能会复发。）——自己加的。这样就导致结论情况的出现，所以加强结论。
