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.

首先，假设题，判断是否有否定句
有
那么A C E入选，其他淘汰
其次，搞清楚原文因果，Bicycle racers  strong demand authorities 三者之间原文已经给出了完整的因果关系，所以答案一定是否定其他与这三个概念相关的可能性
读选项，E high-performance 无关词排除 A  cheap, traditional bicycles 无关词排除
选择C
最后验证C与原文意思是否贴切
贴切
最终选定C
