标题: oldprep-cr2-35求解释~~ [打印本页] 作者: arieslee0410 时间: 2010-12-5 19:44 标题: oldprep-cr2-35求解释~~ 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?
(B) Whether some people might go to a physician for no reason other than to ask for a particular medication they have seen advertised (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 B为什么不对呢？我觉得解释的很通啊 求指点作者: sdcar2010 时间: 2010-12-5 20:56
B) weakens the conclusion because if the physican gives in to a patient's demand for a prescription medication, then inappropriate presecription would become more common.
E) removes the above possibility and makes the conclusion of the arugment bullet-proof. E is a sufficient assumption.作者: arieslee0410 时间: 2010-12-6 14:45
