T-3-Q13. 排除法+推论

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.（有些人两种药都过敏，没有偏重，无效支持；且部分人是否对药过敏与新药的抗reinforce能力无关）

B.A course of treatment with the new antibiotic costs about the same as a course of treatment with either penicillin or erythromycin.（这里只与新药是否比旧药的抗reinforce能力更强有关，与疗程的成本无关）

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

D.Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections（一些医生已经开始开新药而非旧药给病人只是一个事实，有很多原因导致这个结果的发生，比如新药更便宜或者病人指明要等等，不能直接支持新药的抗reinforce能力更强的观点）

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.（因为大多数人无论新药旧药都是吃了三天后就觉得自己好了，那么有两种可能：一个是吃旧药，reinforce没有发生；还有就是吃新药，reinforce可能是要发生而被新药抑制了，也可能是没有发生。显然吃旧药reinforce发生的概率是50%，而吃新药的概率就是接近0%。从而证明了新药的抗reinforce能力更强）
