Question Stats:

59% (02:32) correct 41% (00:33) wrong based on 9 sessions
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. People stop taking their antibiotic because they feel better. The problem with the traditional 7-day cycle is that people feel better sooner than they are fully cured. The wider the gap between feeling better than actually being better the larger the chances of reinfection. With the new 3-day antibiotic, theoretically, feel better time = actual cure time, narrowing the before mentioned gap and reducing reinfection.

C doesn't make sense to me. The passage is talking about strep, so the discussion about other kinds of bacterial infection is irrelevant.

The passage is inferring that reinfection has more to do with patient's discontinuing the 7-day course after 3 days than it does with the penicillin or erythromycin itself. The reason patient's stop taking these drugs early is because they feel fully recovered after 3 days, 4 days earlier than it takes for the antibiotic to eradicate the infection. However, the new antibiotic only takes 3 days to fight off the infection, so reinfection isn't as likely with the new drug.

The way I see it, the larger the "gap" between how long it takes for the drug in question to fight off the infection and the time it takes before people stop taking the drug the more likely the chances for reinfection.

Hope that makes sense!

E, since both drug will make patients feel fully recovered after 3 days, it's safe to assume they will stop taking them after 3 days.

The conclusion here is "reinfection will probably be less common in cases where the new antibiotic is prescribed than in cases
where either penicillin or erythromycin is prescribed" ,Any correct answer will support the premises supporting conclusion or conclusion itself.

The underlying assumption is reinfection occurs due to the bacterias(That causes infection or other bacterias that can support infection causing bacterias) that are not removed due to insufficient course times .C proves that new antibiotic will kill other bacteris as well .

I feel E is out of scope for above argument due to the fact that argument is about occurance of reinfection and not about patients feeling.

Go for E
C is actually irrelevant. Even if the new antibiotic is effective, there won't be less reinfections if people don't take the antibiotics.
Close call with B for me. We have to ask ourselves "why did the people stop taking the medicine?" It is most likely because they felt ok. This means that if most feel ok after three days with the new antibiotic, then there will be less reinfections with new antibiotics.

What is the OA here?

I am between E and C but I think I'll pick C.
E doesn't say anything the probability of reinfection.

I initially thought it was C (its crappy but thought it was the best out of the bunch) but after reading yihwei's reason, E makes more sense and more along the way the GMAT would think.

Interested to know what the OA is.

We are only concerned with reinfection. C only states that the new antibiotics help with bacterial other than strep. This doesn't address whether or not reinfection will be less, more or the same.

I agree with E. The reason people are becoming reinfected is because they stop taking the antibiotics at 3 days.

How does E strengthen the argument though that the new antibiotic is more effective than penicillin or erythromycin with regard to reinfection?

The new antibiotic only needs 3 days to work. If people stop taking it after 3 days they shouldn't be reinfected.

They could be equally effective if used properly, but because more people stop after 3 days only the new antibiotic will be used properly and thus be more effective.

OK, I agree OA is E.

However, what about B? If the drug were too expensive, although it were prescribed, the patients might decide not to buy it.

Please, thoughts on that.
Thanks.
