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?
No industries other than the pharmaceutical industry have asked for an extension of the 20-year limit on patent protection.
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.
There are several industries in which the ratio of research and development costs to revenues is higher than it is in the pharmaceutical industry.
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.
Much recent industrial innovation has occurred in products—example, in the computer and electronics industries—which patent protection is often very ineffective.
原因（前提）：除非发展新药的成本能被销售覆盖，这个要才会上市售卖。
结果（结论）：目前20年的专利机制应该被延长。
其他信息：但是其他行业新的产品，尽管发展成本很高，但是还是在继续的。
评价：所以这个延长是没有必要的。
因：制药业只有能赚钱才能投产
果：需要延长专利时间
评论：不需要延长专利时间（反对因果关系）
问题：削弱专家评论=支持文段当中因果关系
则选项应该：给出需要延长专利时间的支持信息=取非：不需要延长专利时间
A ❌只有制药行业要求这个延长，无关
B ✅专利被通过和新药投入市场需要10年，销售时间少了所以需要延长
C ❌有一些行业的发展成本比药品行业高，讲的是别的事情和延长时间无关
D❌ 现行的法案无法阻止公司提供不一样的替代药物，和延长时间无关
E ❌讲的是其他行业的事情，无关
特别棒！
