JJ一道逻辑，谁帮解释一下？

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.

Answer: E

为啥是E呢？

结论说 新药 比旧药更不可能导致 再次感染

加强题

E 就说 旧药和新药一样是前3天就把人治好了， 但是旧药要七天一疗程 就有可能是因为要防止在感染 所以就加强了结论说的 新药比旧药 更不可能导致 在感染

哈哈 不知道对不对

而且 我有点啰嗦 ~~
