请问OG11-116,先谢过！~

116. 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.

对于正确答案，没有异议，但想请问大家，OG的解释中说，C是weaken结论，这个我觉得还说得通，即别的行业成本比制药行业多；但是既然C是weaken, 为什么A是无关呢？

我想可能是：

题目推论讨论的是成本与费用的关系，而C给出的逻辑关系与作者相反

而A项中只是说可能存在的后果，忽略了“原因-后果”这条线，因而无关

谢谢楼上回答

这题告诉我，类比也可以对结论起支持或削弱的作用。

还想请问，A,是不是就是所谓的out of scope？？在逻辑链之外的话题。

做题的时候觉得这种选项比较难把握，混淆性很强。

个人感觉,ETS有种逻辑思维,就是独立性,在逻辑上出现比较时,会有这样的思维:即使(看上去)A比B多了P这个特点,但这并不能说明该比较能支持A或B优劣的结论，因为两者各有各的情况，简单表面比较并没有体现逻辑上的思维，只有详细阐述其中原因才是最佳答案，

如A选项，除药剂行业外没有别的行业如何如何并不是最佳答案，因为这个如何如何是由B的具体原因导致的

个人见解，供你参考
