17. A 7 day course of antibiotics, either penicillin or erythromycin has been the traditional treatment of streptococcal infections. However, since many patients stop taking those drugs within three days, reinfection is common. Azithromycin, a new antibiotic requires only a three-day course of treatment. Therefore, reinfection will probably be less common in cases where Azithromycin is prescribed than in cases where either penicillin or erythromycin is prescribed.
Which of the following, if true, most strengthens the argument?
A. Azithromycin has been shown to be effective in eradicating bacterial infections other than strep.
B. Some physicians have already begun to prescribe Azithromycin instead of penicillin or erythromycin for the treatment of some strep infections
C. Some of people who are allergic to penicillin are likely to be allergic to Azithromycin.
D. A course of treatment with Azithromycin costs about the same as a course of treatment with either penicillin or erythromycin.
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.

My choice is D.
