[求助]T-3-Q13

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?

1. Some of 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.

I can't understand why E?

Please show me the way out.

Thank you !

I cannot understand as well

My choice is D, which acts as a fact to support the conclusion.

以下是引用bmlf_001在2007-8-5 18:15:00的发言：
这道题的意思是，病人在吃药（不管是以前的药还是新药）后的三天，都会觉得自己好了而不继续吃药，但以前的药需要连续吃7天才能完全好，不会复发，所以以前有很多人复发。但是，这个新药在吃了三天之后病已经完全好了，所以就算病人停止服用也不会复发了。Understand?

"这个新药在吃了三天之后病已经完全好了，所以就算病人停止服用也不会复发了"?

But E says: Regardless of whether they take a traditional antibiotic or the new one

that is, the drugs in the question can be either new ons or old ones. How to break this?

如果病人服药三天后，不管新药旧药，都感觉痊愈，那么服旧药的人可能就会感染，服新药的人就不会了。这样吗？
