This is a good example of a question with good intent, but with a poor outcome. Answer choice E does nothing for the argument and those on here who have argued for it are making a common flaw in interpreting it.

There is a big difference between something because an outcome and that something being the only outcome. In this case, answer E says "most patients feel fully recovered after taking the drug for three days." This answer says nothing about when the patient first starts feeling better under the new drug, only that, at the three day mark, the patient feels better. The patient easily could have started feeling better during day 1 or day 2. Therefore, everyone has incorrectly interpreted this to fix the issue that patients might start feeling better before the dosage of the new drug is complete and stop taking it.

For example:

Quote:
With the new medicine too they would start feeling better only after 3 days; but by that time the new medicine would have done its job and hence no re-infection. (emphasis added)

However, the word "only" appears nowhere in the actual answer choice.

The obvious intention of the author was to have E eliminate the possibility that people stop using the new drug because they feel better before they finish treatment. E should therefore instead say:

(E) Regardless of whether they take a traditional antibiotic or the new one, most patients DO NOT feel fully recovered afterUNTIL taking the drug for three days.

Fortunately, we do not see this as a trap answer too much on actual GMAT questions. However, if you were to work some LSAT CR questions, you would see this come up a lot, especially in assumption, inference, and flaw questions.

Side note: B seems like the best alternative because it seems to eliminate a potential barrier. Whenever consumer choice is involved, cost is definitely relevant. In this case, B seems to eliminate the problem that the new drug is more expensive so people won't choose it. However, it has no effect because the conclusion limits the scope to "in cases where the new antibiotic is prescribed." Therefore, there is no consumer choice here, which, in this case, makes B irrelevant.

this is the best example for those who have gone through powerscore cr Scope section.

If an argument discusses of a new technique, than any answer that explains federal and monetary policy is out of scope whereas the correct answer will be applicable to surgery and medicine.

Definitely B is out of scope.

Pls correct if i am wrong and raise question if you have any on the below explanation.

First of all key points in the argument.
1. Many people discontinue the course after 3 days
Assumption:- May be they get cured
2. Re Infection chances in those individuals.
Assumption:- To avoid re infection take the complete course. In nutshell dont discontinue.
3. New drug is a 3 day course, it provides cure in 3 days. Hence Patients using it will have lesser chance of re infection.
Assumption:- Patients will adhere to their 3 days habit and complete the course.
Completion of course is important for re infection not to occur.

B and E are contenders thats for sure....B is ruled out as discussed in the preceding post.

E is the best option and also E affirms that Older treatment of 7 day course gives remedy from the disease in 3 days. Thereby strengthening the fact that it is non adherence to the course that it causes the re infection. Hence 3 day course will not cause re infection as people are used to 3 day pattern and it also cures the disease. Hence the people sticking to course of 3 day will prevent the reinfection

[quote="avdxz"]IMO: E

Main issue is: People seem to stop taking the antibotics after 3 days. So a drug has to be effective in 3 days.

A. Some of the people who are allergic to penicillin are likely to be allergic to the
new antibiotic.
>> Out of scope. Eliminate.

B. A course of treatment with the new antibiotic costs about the same as a course of
treatment with either penicillin or erythromycin.
>> Irrelevant. Does not explain why people stop taking antibiotics after 3 days. Eliminate. (Note that if you were using the 2 of 5 rule, this would be one of the 2 remaining options)

C. The new antibiotic has been shown to be effective in eradicating bacterial
infections other than strep.
>> Out of scope. Eliminate.

D. Some physicians have already begun to prescribe the new antibiotic instead of
penicillin or erythromycin for the treatment of some strep infections.
>> Irrelevant. Eliminate.

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 choice because it does not weakening nor irrelevant.

Why E ?

The option says "Regardless of whether they take a traditional antibiotic or the new one, most patients feel fully recovered after taking the drug for three days. " They just feel they have recovered but may not have actually recovered after the course of medicines.

IMO, B.
For me it was between B and D. D was not strengthening as much as B.

Experts plz help me with this one.

Conclusion says: reinfection will probably be less common in cases where the new antibiotic is prescribed than in cases where either penicillin or erythromycin is prescribed

But E says Regardless whether its Traditional or New one, most patient fully recovered after taking the drugs for three days. . it means what is the use of New drug. . the old drug can do the same work in three days with out reinfection. So it does not give any extra point to believe in Conclusion.

but first three A,B & C Weakens the argument and D has no effect in this. I opted D . I found E) to distort the entire argument.

Option E.
If the patients will feel okay only AFTER THREE DAYS,then they won't stop taking the new drug BEFORE 3 DAYS.And the new drug just takes 3 days to cure the infection.Hence the argument that the new antibiotic drug will be more effective is strengthened as THERE WILL BE NO REINFECTIONS AS COMPARED TO THE ALTERNATIVE TRRATMENT.

HI,

My Doubt here is that , if you observe the conclusion very closely ,it predict that the Reinfection cases be less as compared to the previous tradition antibiotics case.As the all the other options except E are easily eliminated,Still Option E just says that Regardless of traditional or New one. People starts feeling better .Does that means that reinfection won't occur.Just saying Feeling better assured us that reinfection won't occur.

Thats my Doubt .

where either penicillin or erythromycin is prescribed.

so bcos people will stop taking after 3 days, reinfection will be less common amongst the group who take the latter and not pencillin

The conclusion says chances of reinfection are less if new anitibiotic is taken.
But E says that a person might take any medicine to be cured.
How is this strengthening the conclusion?

Good one
The distinction in the question is about being CURED Vs. about FEELING BETTER

People "FEEL" better after three days hence they stop taking penicillin and Erythromycin (but they have not fully CURED. Remember peniillin and ertyomicin takes 7 days).

People when taking new antibiotic will again feel better after 3 days . The real difference is that they will actually be cured because new antibiotic works only in 3 days effectively curing the patient and also removing any chance of reinfection

A. Some of the people who are allergic to penicillin are likely to be allergic to the new antibiotic. --- This is not helping our conclusion.

B. A course of treatment with the new antibiotic costs about the same as a course of treatment with either penicillin or erythromycin. ---- well if so why not take new drug --- positive

C. The new antibiotic has been shown to be effective in eradicating bacterial infections other than strep. --- means if something else then also it will help --- positive

D. Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections. ---- that doesnot help

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. --- most patients feel good , is this sufficient to make sure that reinfection will not happen. i think no. this argument have flaw.

I will go with C.

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.

Pre-thinking: reinfection will decrease as 3 day course will be successful. In other words for the new course to be successful, patient needs to take that new antibiotic for 3 days i.e., complete course. Like patients reduced 7 day course to 3 days, they should not reduce this duration and should take them for 3 days.

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............keep it a side.

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 concern here. OFS

C. The new antibiotic has been shown to be effective in eradicating bacterial infections other than strep............other than strep will not make sense here.

D. Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections.............does not matter. OFS

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............So irrespective of course duration or health consciousness, they will take this medicine for 3 days for sure thereby making course successful.

Got this question wrong in the when I got it in my practice test. I marked (B) but I realized my mistake after reading other posts in the forum.

There are two problems with (B):

1) Even if cost was a concern, (B) still is a neutral option (as the cost is same for both). It neither helps nor hurts the adoption of the new drug.
2) Like others have pointed out, cost is not discussed in the question stem.

The stimulus of this question is interesting because it does not tell you why do people stop taking the drug after 3 days. It could be because of number of reasons. And that is what makes the choice (E) correct.

Choice (E) gives you two pieces of information (and how they are used to strengthen the argument):

1) patients feel fully recovered in 3-days after taking the traditional drug
=> this part does not really strengthen the main conclusion of the argument but adds to the premise of the stimulus
=> it tells us the reason why patients stop taking the drug

2) patients feel fully recovered in 3-days after taking new drug
=> So now even with the new drugs patient will take it for least 3 days thus curing the patients fully because that is how much time the new drug needs to be effective.

In summary, you have to use one part of the choice for additional premise of the argument and then use the second part of the choice to qualify why the new drug will be effective.

I modified the question below (highlighting my changes), to make my analysis more clear:

Quote:
The traditional treatment of strep infections has been a seven-day course of antibiotics, either penicillin or erythromycin. However, since many patients, feeling fully recovered, 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. With the new drug, most patients feel fully recovered only after taking it for three days.

Hope it helps. Let me know if I missed something.

It's honestly a very confusing question imo- I picked up on E then thought oh wait that weakens, but then reread several times and realized something. What E is trying to state is that because people tend to feel better after three days then that would then actually coincide with the full length needed for the medication to work- people get reinfected from penicillin because they stop taking it before it starts to fully work but if that threshold for recovery is usually at three days then people will have taken enough of the new medication for it to work and for them not to be reinfected. Ehh
