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.
原文意思：技术的发展和需求量有关系，说技术只有哪些专业人士才会感兴趣，所以技术受制于政府对于自行车比赛的标准的设定。
题目分析：A强调高技术自行车的市场和低端自行车市场之间的关系，没提，杀。B自行车技术的革新主要是小作坊发明出来的而不是生产商发明的，没提，杀。C说比赛选手对于自行车的demand以及官方是否认为这种需求就是标准，反复在谈的就是需求量和这个需求量是否是官方标准，与原文反复强调的信息类似，留着。D说技术保守派的起源，没说过，杀。E那些制定标准的政府并不了解自行车最新的设计，没说，杀！
