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?
Some of the people who are allergic to penicillin are likely to be allergic to the new antibiotic.
A course of treatment with the new antibiotic costs about the same as a course of treatment with either penicillin or erythromycin.
The new antibiotic has been shown to be effective in eradicating bacterial infections other than strep.
Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections.
Regardless of whether they take a traditional antibiotic or the new one, most patients feel fully recovered after taking the drug for three days.
用传统抗生素治疗感染需要吃7天药，很多病人在3天以内就自主停药了，因此再感染很常见。用新的抗生素治疗只需要吃3天药，所以重新感染的情况会比传统治疗更少。问support
choice e, 不管使用传统还是新抗生素，大多数病人吃3天药就完全康复了。correct，说明用新的抗生素，连着吃3天是可以保证治愈的。如果新药液的疗程也要求3天以上的时间，那么重新感染率就很难说
