GMAT逻辑机经1：新药广告投放与销量

　　【题目】

　　【V1】三年前美国政府准许了perception(不确定单词)meditation的广告投放，然后发现三年过去大量投放广告的药品销量增加。问加强。选三年里出现了很多新药。

　　【v2】三年前美国政府准许了perception meditation的广告投放，然后发现三年过去大量投放广告的药品销量增加。 结论是这些广告导致了人们主动要求医生来开这些药。 问加强。我选了B， 句子结构有点长 ，意思好像是说与这些打广告药相比，有些不需要医生开处方的药要便宜些，并且医生认为这些不需开处方的便宜药效果并不差。 看的比较匆忙，但应该没错。

　　【V3】美国政府准许投放广告以后，发现投放广告的药品销售量增加。结论是广告的作用导致人们主动要求医生来开药。问加强。E.三年里出现了很多其他新药。B.有些不需要开处方的药便宜些，并且医生认为这些便宜药效果并不比做广告的药差。B的答案够长，看了好几遍，觉得很拗口，脑子也没转过来，就选了E。是完全忽略了“人们主动要求医生开药”吧。。。如果纯粹是广告作用导致销量增加，选E是没错。如果是“人们主动要求医生开药”这个点的话，就觉得B原来还是有店道理啊，意思就是：医生本来没必要开这些药的，但是病人要求了，所以开了。。。。但会不会太绕了?当中还有一层前提是，病人要求开医生就会开呢?。。。。。。想着想着，还是觉得E了。

　　【类似题目】

　　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

　　选择：E
