这是涛涛GWD31套里的第15套第40题

TT   GWD-15-Q40:

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 these advertising claims 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, the objection provides no grounds for concern.

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

1. Whether nonprescription medications can interact with any of the prescription medications that could be advertised to the general public and block the action of those prescription medications
2. Whether some people might go to a physician for no reason other than to ask for a particular medication they have seen advertised
3. Whether the proposed law requires prescription-medication advertisements directed to the general public to provide the same information as do advertisements directed to physicians
4. Whether physicians are more likely to pay attention to advertising directed to the general public than to advertising directed to physicians（无关）
5. Whether physicians are likely to succumb to pressure from patients to prescribe inappropriate medication.

这题好象A(非处方药)D(广告对象)是无关的，其它都看不明白， 

还有，评价题的“回答不同，分别对原文起到加强或削弱的作用”该怎么理解，比如以此题为例。

快考试了，哪位牛牛给解释一下，谢谢了！

赞成楼上。同时给点逻辑题中可用的排除法：1\带some的，只能表明“一些”，

不是majority，所以通常排除。2\代比较结构的，原文中如果没有比较时，排除。如

果有，看比较双方是否在原文中出现，如果没有，排除。如果有，看在比较什么，原

文中没有，排除。一般，第一步就排除了。纯属个人意见，请谨慎
使用，呵呵

楼上二位的讲解真是相得益彰,非常感谢！

我又仔细看了题,原先对 inappropriate 这个关键词的理解也不深入。5楼说的这两

个办法确实如此，不必谦虚。其他讲解和讨论中也常提起过，但真到做题应用时还是

有距离。其实你能有如此感觉，已经可以去考了，我觉得GMAT是一种感觉，有了感觉，

不一定非要学多长时间才去考试。只是我到现在还找不到这种感觉，这种心情真是

苦闷！
