35.  

It is illegal to advertise prescription medications in Hedland except directly to physicians, either by mail or in medical journals.  A proposed law would allow general advertising of prescription medications.  Opponents object that the general population lacks the specialized knowledge to evaluate such advertisements and might ask their physicians for inappropriate medications.  But since physicians have the final say as to whether to prescribe a medication for a patient, inappropriate prescriptions would not become more common.

Which of the following would it be most useful to establish in order to evaluate the argument?

(A) Whether advertising for prescription medications might alert patients to the existence of effective treatments for minor ailments that they had previously thought to be untreatable

(B) Whether some people might go to a physician for no reason other than to ask for a particular medication they have seen advertised

(C) Whether the proposed law requires prescription-medication advertisements directed to the general public to provide the same information as do advertisements directed to physicians

(D) Whether advertisements for prescription medications are currently an important source of information about newly available medications for physicians

(E) Whether physicians would give in to a patient's demand for a prescription medication chosen by the patient when the one originally prescribed by the physician fails to perform as desired

answer is E.

想问一下，答案D 为什么不对啊？

如果医生也被广告误导了呢？当医生的inforamtion 也是来源于广告的，医生可能也会给出inappropriate medications 啊！

楼主想多了...D选项只是说, 广告是否是医生了解新药物的重要来源, 并没有引申出医生一定会被误导啊...

如果D选项改成, 医生是否会被广告所误导,那么就可以是答案了...

再用评价题目的方法分析一下, 如果选项的真或假,可以对结论起到加强或削弱, 那就是答案

结论简单说就是广告不会导致inapproprate

D: 是重要来源为真, 可能削弱,也可能不削弱,因为如削弱需要一个前提,就是医生会被误导..

反之如果为假, 可能加强, 也可能不加强...理由同上, 所以这个不能起到评价作用

在看看E选择, 楼主体会一下

如果为真, 那么广告就会导致inapproprate,削弱

如果为假, 那么广告就不会导致inapproprate, 加强

所以可以对结论起到评价作用

gmat逻辑要基于原有信息,不要擅自进行推理引申

不理解B噢。。如果是肯定，那就是加强，支持医生会帮病人把关；如果否定，那

病人根本不去找医生，自己决定吃药，那不就是inappropriate prescription?

我觉得是因为题目说的是会不会inappropriate prescription，应该重视的是医生的主动性吧。

B的是否都取决于病人自己，所以不对。
