Great discussion here. Quick note:

As future MBA students, GMAT test takers tend to be too focused on costs. I can think of at least a few CR problems off the top of my head in which something related to "cost" is a trap answer. If you're going to choose an answer that relates to cost, I would really encourage you to spend a few extra seconds asking yourself whether the cost of the program or project really has anything to do with the argument itself.

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.

This post was
BOOKMARKED
Cost of the antibiotics is not the issue because it was not discuss in the stimulus. Furthermore, if the new antibiotic cost more than the old antibiotic, then how much more of the cost will it actually impact people's decision in buying the drug? Perhaps the antibiotic cost \$1 more, which would not affect people decision in buying AB. What if the AB cost \$100 more, then that would affect people decision in buying thr AB. Thus, when you have to make an assumption for that answer choice, then its incorrect.

Hello everyone,
picking up this old thread thanks to my daily delivery of GMAT delights in my emails

It's hard to undersand how E really strenghtens the argument.
Here is my explanation.

As said before, the argument is: patients taking old drug often stop treatment after 3 days, which leads to more reinfection cases; new drug is effective in 3 days, so reinfection should occur less often.

Choice E gives an explanation for the first part: patients stop after some time (3 days) because they feel better, even though the treatment is not over.
The same thing could happen with new drug: active in 3 days, fine, but what if you feel better after a couple of days? Well, choice E addresses this concern, hence reinforces the argument.

Hope that's clear and helpful.

But I'll add that in less than 2 minutes, you should tackle the question differently: all the "out of scope" answer choices can be eliminated quickly. The argument is about reinfection/time for the drug to be effective/time patients take drug (~patients behaviour - inferred related to psychology).

E is the only choice that has all that, so it's enough to pick your choice without drilling too much into logic

my 2 Euros (not worth much these days)

cheers to all and keep it up!

E

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.
Weakens the argument
(B) A course of treatment with the new antibiotic costs about the same as a course of treatment with either penicillin or erythromycin.
Out of scope - cost not mentioned in the argument
(C) The new antibiotic has been shown to be effective in eradicating bacterial infections other than strep.
Out of scope - other bacterial infections not referred to in the argument
(D) Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections.
Neutral. Some can equal 0 or 1 or greater.
(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.
Correct Answer. As most patients feel fully recovered after 3 days, they are more likely to stop continuing the course. having finished 3 days on the new course lowers the probability of reinfection more-so than penicillin or erythromycin.

the answer to the question is E as E clearly strengthens the argument

E makes the most sense. Cost factor in B is just a trap.

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.
If so, people are equally unlikely to take both. Irrelevant.
(B) A course of treatment with the new antibiotic costs about the same as a course of treatment with either penicillin or erythromycin. Cost is out of scope.
(C) The new antibiotic has been shown to be effective in eradicating bacterial infections other than strep. Talks about other infections. not interested in them.
(D) Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections. This does not show that the new drug is better at not causing re-infection.
(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. Correct. If the patient feels fully recovered, he will not take the drug anymore. By the end of these three days, however, the prescription of new drug will be completed. Hence, lesser chance of re-infection.

(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.

conclusion : reinfection would be less common in case of new antibiotic than either penicillin or erythromycin.

thus as per conclusion, our scope is limited to cases related to reinfection or relative effectiveness of two medications rather than about their relative cost, other infection or allergy. hence A,B, C could be crossed out.

D could be taken out even if some physician prescribe drug, people could still stop it taking after 1, 2 or 3 days, hence drug effectiveness is not directly dependent on physician

[color=#FF0000]E could not find any solid evidence to mark out E , so ultimately after POE I am left with E.

My only concern with E is people stop taking penicillin within 3 days, so this options definitely provide evidence that penicillin would not be effective and reinfection would occur, but how does this option provide justification tht chances of reinfection would be less for newer medicine [/color]
