T-3-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 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.

个人觉得应该选择B，因为价格一样可以排除因价格问题而引起的需求减少，只有在病人有需求的时候才能保证减少复发。

但是答案说是E，很是想不通，希望NN指点

这题跟价格没有关系阿, 题干说传统药要7个疗程, 好多人吃了小于三天就不吃了, 所以有好多复发的 , 但是新药只需要三天就可以根治==>新药比旧药不容易复发

问STRENGTHEN

E选项就正好了, 是说病人无论吃什么药, 一般三天都觉得康复了, 所以都不吃了(这时候, 旧药就不行拉)
