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.

Please explain ur answer choices

is it E?

With penicillin or erythromycin the reinfection can occur if the course is stopped after 3 days wheras with Azithromycin will reduce chance of reinfection after 3 days. As most patient feel recovered after 3 days they may stop taking antibiotics after 3 days and if patient use Azithromycin patient they will not get reinfection thus strengthening conclusion that reinfection is less likely.

conclusion is with new drug reinfection is less likely. A & B don't support it.

Yes, certainly E. The other statements are irrelelvant. E explains why some stop their treatment on older antibiotics after three days- they feel better. Well, maybe on this new antibiotic, people will feel better after one day and also stop the treatment early. E addresses this concern.

I think the answer is B.

Some physicians have already begun to prescribe Azithromycin instead of penicillin or erythromycin for the treatment of some strep infections

It strengthens the fact that the number of reinfections will be reduced as its already in use in those areas.

D strenthen but out of context of evidence .

in weakening, strenthening and assumption quesions usually there are weakening , strenthening and assumption answers but these answers are out of context of evidence and so wrong. this is very tricky and most test taker choose this fatal answers.

weakening, strenthening answers and assumption answer must be in context of evidence.

pls read "critical reasoning 101" for more on this

in strenthening (and weakening and assumption) questions. the correct answer must be

1, strethening (increase beliveing in conclusion, pls, see Kaplan book)
2, in context of evidence

the answer which strenthen but out of context is very attractive but wrong.
