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?

1. Some of the people who are allergic to penicillin are likely to be allergic to the new antibiotic.

2. A course of treatment with the new antibiotic costs about the same as a course of treatment with either penicillin or erythromycin.

3. The new antibiotic has been shown to be effective in eradicating bacterial infections other than strep.

4. Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections.

5. 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

我觉得D才是在加强呢.....不明白E怎么加强的？ 

结论是减少重新感染的可能性

E说3天就觉得好了 题目又说很多人吃3天药就停 老药要7天一疗程 新药只要3天 所以 吃老药的并没有完成一个疗程 而吃新药的已经完成了 因此吃新药的人不容易重新感染

如果此题要加assumption 可以是：如果病人吃完一整个疗程的药，重新感染的可能性会降低
