The pharmaceutical industry argues that because new drugs will not be developed unless heavy development costs can be recouped in later sales, the current 20 years of protection provided by patents should be extended in the case of newly developed drugs. However, in other industries new-product development continues despite high development costs, a fact that indicates that the extension is unnecessary. Which of the following, if true, most strongly supports the pharmaceutical industry’s argument against the challenge made above? (A) No industries other than the pharmaceutical industry have asked for an extension of the 20-year limit on patent protection. (B) Clinical trials of new drugs, which occur after the patent is granted and before the new drug can be marketed, often now take as long as 10 years to complete. (C) There are several industries in which the ratio of research and development costs to revenues is higher than it is in the pharmaceutical industry. (D) An existing patent for a drug does not legally prevent pharmaceutical companies from bringing to market alternative drugs, provided they are sufficiently dissimilar to the patented drug. (E) Much recent industrial innovation has occurred in products—for example, in the computer and electronics industries—for which patent protection is often very ineffective.
重新分析这道题的时候发现了两个问题~
问题一:虽然排除法最后只能选B 但是深分析下来 对B选项还是有点问题 B选项只说出了The pharmaceutical industry的 Clinical trials of new drugs需要10年,但是没有指出other industry不存在同样需要长时间的trial,难道是要加入常识吗~?
问题二:A选项 仔细分析是否ask for与判定延长年限的必要性无关 但是根据类比推理模式: 类比推理不是只要说出不同就会导致类比削弱(无论这个不同是否逻辑影响到结论) 因为A说了The pharmaceutical industry和other industries 的不同,削弱了类比条件 ,从而against the challenge,这样的想法在哪里错了啊~?
有没有人可以帮我解答一下~
