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.

E.
All the rest are irrelevant. Patients stop taking drug because they feel better after 3 days. If the new treatment takes 3 days, then re-infection won't occur.

I choose E.

Answers A, B, C and D either aren't relevant or discuss items not mentioned in the article.

The answer is B. The next point that has to be evaluated is the cost of the new antibiotic. If there is no cost variations, the new antibiotic will serve the purpose better.

i dont agree with some of my friends, who have mentioned the answer as E. We are discussing an argument on relapse of the infections which occurs when the patients stops using pensillin after 3 days of use. The new antibiotic addresses this core issue as it cures the infection in 3 days without the possibility of relapse. The answer E says that the patient feels cured but he is actually not and has to continue using the medicine for a longer time.
