标题: 求助CR一道题，好像也搜不到来着 [打印本页] 作者: Lemonlexie 时间: 2019-7-16 16:07 标题: 求助CR一道题，好像也搜不到来着 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?
A. Some of the 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.
1. many patients stop taking old antibiotics within 3 days will be reinfected, 那就代表, at least 1 of the patients will " not " be infected
2. require only 3 days course of treatment - then we must assume that at least one of the patients taking the new med will " not be infected "
所以, 缺口在哪？ 作者的必要假設在於服用新藥三天的病人必定至少有一位是康復的
A. 過不過敏對於復發率毫無相關
B. 價錢多寡對於復發率毫無相關
C. 新藥可以治癒其他疾病不代表新藥治癒strep此疾病的比例會大於舊藥治癒strep
( 作者比較的不是功能的多寡, 而是某一功能的效率程度）
D. 有一些病人已經開始服用新藥不代表新藥的確比舊藥有用
E. 不管是新藥還是舊藥, 多數的病人三天後都會完全的康復 - 此為正確答案, 至少有一個可以有全部的概念, 而如果服用新藥三天的病人有多數是康復的, 那就代表, “ 至少有一位服用新藥可以康復的病人”的必要假設可以成立。

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.
feel fully recovered——just what patients feel，maybe some haven’t recovered but stop【原文说 However, since many patients stop taking those drugs within three days,】这种情况就会 reinfection，if traditional drugs need 7days， though3days patients feel recovered.
and 原文【 A new antibiotic requires only a three-day course of treatment. 】保证三天就好。
reinfection will probably be less common--use new drugs--减少了可以避免出现的reinfection--用三天确定治愈，而非三天使得有好转却让病人停药的traditional drug
