Since 1990 the percentage of bacterial sinus infections in AQADESTAN that are resistant to the antibiotic perxicillin has increased substantially. Bacteria can quickly develop resistance to an antibiotic when it is prescribed indiscriminately or when patients fail to take it as prescribed. Since perxicillin has not been indiscriminately prescribed, health officials hypothesize that the increase in perxicillin resistant sinus infections is largely due to patients’ failure to take his medication as prescribed.

Which of the following, it true of Aqadestan, provides most support for the health officials' hypothesis:

A) Resistance to several other commonly prescribed antibiotics has not increased since 1990 in Aqadestan

B) A large number of Aqadestanis never seek medical help when they have a sinus infection.

C) When it first became available, perxicillin was much more effective in treating bacterial sinus infections than any other antibiotic used for such infections at the time.

D) Many patients who take perxicillin experience severe side effects within the first few days of their prescribed regimen

E) Aqadestani health clinics provide antibiotics to their patients at cost

--------------------------------

Can any one explain how E does not support conclusion?

My analysis: If health clinics bear the cost of the antibiotic prescription means that they will not prescribe perxicillin indiscriminately. Thus it should be the only other way the resistance has been taking place. And this analysis strengthens the argument.
The assumption in this analysis: The clinics, bearing the cost of the medicines, will not prescribe those medicines randomly.

In fact for C one can say that GMAT assumes that: much of the people who experience severe side effects within first few days of treatment fail to take the medication as prescribed.

Thus which assumption to choose over the other?

Someone please help!

thought I see d is best. I think that d require an assumption, which is patients will stop taking the medicine.

correct choice need an assumption. this is the case whichh makes me uneasy

I agree. Isn't it a very big assumption to think that the patients will stop taking the medicine? What if they not? This makes me think , then we can put such an assumption in any other answer choice to make it work, for instance in B) A large number of Aqadestanis never seek medical help when they have a sinus infection. So we can assume they might be using antibiotic perxicillin on their own incorrectly and as a result cause perxicillin resistancy ? or in C , perxicillin was much more effective in treating bacterial sinus infections than any other antibiotic used, and may be, we can assume, it became ineffective because people started to use the medicine incorrectly on their own.

D sounds strange and weird but D is correct.
Using POE, ones can eliminate A,B and E b/c they are out of scope. A and B do not relate to pencixiline; E talks about the cost.
D is much better and C b/c C discusses about other drugs and the comparison.
How D can be correct? It is because D gives a reason for patients to take the drug in wrong ways. Here is a special case of a pattern in gmat. Normally, in a gmat question, there can be many premisesm, but one conclusion. The pattern that gives a cause for a premise is normally wrong; however, in this question, the pattern is correct in D.

A) Resistance to several other commonly prescribed antibiotics Ins not increased since 1990 in Aoadestan. Other antibiotics are out of scope

B) A large number of Aqadestanis never seek medical help when they have a sinus infection. It is a trap. Maybe Aqadestanis do not cure at all

C) When it list became available, perxicillin was much more effective in treating bacterial sinus infections
than any other antibiotic used for such infections at the time. Out of scope. Effectivness is not discussed in the argument.

D] Many patients who take perxicillin experience severe side effects within the first few days of their
prescribed regimen. Correct. If antibiotics are not prescribed indiscriminately, then the only explanation of side-effects can be patients' failure to take as prescribed

E) Aqadestani health clinics provide antibiotics to their patients at cost. Doesn't help to explain

Lets look at he answer choices. Hope it helps!

I believe and Know side effects are normal for some drugs. They are even on the drug notice so I don't understand this..

can't we not think for E: at cost, so the antibiotics cost something to the patients and some of them just won't buy?

what Ankurgupta03 is saying is here is totally correct( and ankur . I will just like to add on to option B.

B) A large number of Aqadestanis never seek medical help when they have a sinus infection.
This option can go in any of the ways mentioned below
i) Patients take perixicillin
ii) patients dont take perxiccilin but take some other medicine
iii) patients dont take medicine at all.

In all of those situations, it is very tough to make any decision
So B is inconclusive


why not B?
1. It tells about those who do not seek medical help whereas the argument talks about patients who seek help.
2. It talks about Sinus infections, not Bacterial Sinus infections.

1. option a: not resistance to other medi, ( which is not discussed ) -> irrelevant
2.option b: asking for help and not following prescription are different -> not relevnt
3. option c: earlier it was more effective , opens a debate that whtr now it is working or not ? -> not concrete and not touching upon the point, which is ' not following prescription'
4. if facing side effect -> might be a slightest chance that people may stop taking it and resume it later. -> possibility is there
5. even if available at cheap cost, it is not sure people are buying or not. hence not buying and not following are diff
