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.(E)

   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.

如果选择E的话不就说明新药和旧药没有区别了吗

E的意思是说在服药后3天,病人感到完全好了,然后停止服药

老药不是全好,会复发,需要reinfection
        

新药会全好requires only a three-day course of treatment

还是老套,最后一句:

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.

好了就不用reinfection 了,所以support

呃,说实话你们的观点我都不是太明白

mymengming不知道是我对E没理解还是你没理解呢,我觉得E是说,不论是老药还是新药,三天后会全好,这样老药的性质不是跟题目冲突了吗

allen你能不能再解释得明白点呢?

题目：老药要吃7天。缺陷：病人只吃3天——导致疾病复发

     新药只用吃3天

结论：用新药会较少导致复发

mm有没有想过，为什么老药只吃三天就不吃了呢？如果是因为吃腻了什么的或者忘记吃了等，有可能新药大多数病人只吃一天就不吃了（按照老药不吃的比例推算）

所以e首先解释了，老药不吃是因为3天后症状没有了，病人以为好了，所以不吃了。（但是实际上没有好）

但是新药只用吃三天，而且必须要用三天才能没有症状。所以病人一定要服用完疗程，才会不吃它。这样就加强了结论

这道题有点排除他因的意味

同意

注意这句most patients feel fully recovered after taking the drug for three days.

只是感觉上

老药感觉好了其实没有好

新药感觉好的时候已经好了

thx
