OG11 逻辑116
The pharmaceutical industry argues that because new drugs will not be developed unless heavy developments costs can be recouped in later sales,the current 20years of protection provided by patents should be extended in the case of newly developed drugs.However, in other industrial new-product development continues despite high development costs, a fact that indicates that the extension is unnecessary.
看不懂题目啊．．．．大家看看
药厂说除非昂贵的研发费用能够从后期的销售收回，将不再开发新药，当前的20年的保护期应该延长；然而，在其他工业尽管有很高的研发费用，新产品仍继续发展，这个事实证明延长保护期是不必要的。
LZ最好取贴逻辑区
