52.   (34413-!-item-!-188;#058&007570)

 

The technological conservatism of bicycle manufacturers is a reflection of the kinds of demand they are trying to meet.  The only cyclists seriously interested in innovation and willing to pay for it are bicycle racers.  Therefore, innovation in bicycle technology is limited by what authorities will accept as standard for purposes of competition in bicycle races.

 

Which of the following is an assumption made in drawing the conclusion above?

 

(A) The market for cheap, traditional bicycles cannot expand unless the market for high-performance competition bicycles expands.

(B) High-performance bicycles are likely to be improved more as a result of technological innovations developed in small workshops than as a result of technological innovations developed in major manufacturing concerns.

(C) Bicycle racers do not generate a strong demand for innovations that fall outside what is officially recognized as standard for purposes of competition.

(D) The technological conservatism of bicycle manufacturers results primarily from their desire to manufacture a product that can be sold without being altered to suit different national markets.

(E) The authorities who set standards for high-performance bicycle racing do not keep informed about innovative bicycle design.

答案为C

请问选项E为什么不对呢？？

怎么没人回答阿，我也想知道

技术保守和市场需求的关系：

只有比赛者关系技术进步并付钱

结论：技术进步有限

因为：技术进步反应市场需求

技术进步有限--市场需求有限（市场需求即比赛者的需求--比赛者所占市场份额少

厂家保守源自主管部门没要求，和比赛者无关
主管部门保守源自比赛者没有求。

比赛者--->主管部门--->厂家
填上gap

C和E选项的分析：（不知道如下思路和方法是否正确，请NN鉴定）


正面解题：关键是对“Therefore, innovation in bicycle technology is limited by what authorities will accept as standard for purposes of competition in bicycle races.”的正确理解。创新受到竞争标准的限制，说明只接受符合标准的，也就是C说的：过于创新的不care。E中标准如何制定无所谓，反正racer只跟着标准走。

Assumption解题技巧：（取非削弱）
取反C：racer关心标准之外的创新，那么创新应该不被限制?削弱结论，则为正确选项
取反E：制作标准的人被告知创新的设计，那么标准符合创新?没有削弱结论。不是正确选项
