The traditional treatment of strep infections has been a seven-day course of antibiotics, either penicillin or erythromycin. However, since many patients stop taking thouse drugs within three days, reinfection is common in caes where these drugs are prescribed. A new antibiotic repquires only a three-day cuorse f 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 penicilin are likely to be allergic to the new antibiotic.
B. A course of tretment 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 eradcating bacterial infections other than strep.
D. Some physicians have already begun to prescribe the new antibioticinstead of penicillin or erythromycin for the treatment of some strep infecitons.
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.
The right answer is E.
My wrong answer was D.

E支持了题目中 many patients stop taking thouse drugs within three days~~~因为它说大家觉得自己痊愈啦，所以i就不肯吃药啦~~于是新药当然比旧药要好啦 其他选项貌似无关~~
