请教OG-103题

103. 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 purpose of competition in bicycle races.
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
看不懂这部分的意思以及解释
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.
解释
If racers, the only cyclists interested in innovation, created a strong demand for innovations for purposes other than official competition, then the conclusion would not follow. Therefore choice C-which asserts that racers generate no such demand-is assumed and is the best answer.
不明白这里innovations for purposes 跟 official competition 是指什么？
谢谢指点！

嗬嗬，终于又看og的了。和偶的pace差不多嘛，昨天刚做完这题。

to put it simply,原题在说：需求决定保守，赛车需要革新。结论：革新仅限于如下范围：当局承认的为了赛车而制定的标准。

这里innovations for purposes other than official competition 是指结论的取非。

我觉得，只要明白了原题结论的含义，逻辑是显而易见的。仔细体会题干中最后一句话，且要明白authorities 就是 officially。

好像明白些了，但还是感觉很不顺畅，在体会体会。
谢谢啊！

原文的意思:
自行车在技术革新上的保守体现了其制造商所针对的需求. 骑自行车的人中, 只有赛车手才对技术革新感兴趣并愿意pay for it. 因此,自行车技术上的革新仅限于那些权威(指racer)所接受的可以用于比赛的标准.

accept as: His new speech was accepted as the milestone for human liberty.

B是标准类型的ETS答案. 原文说: 因为是racer推动了innovation,所以革新只是用于比赛. 这里的假设就是racer所要的innovation只和race有关. 取非原文结论不成立.

这题好像选c吧。。？？

奇怪，og 明明写着c的？？

支持选B，虽然OG的答案是选C。因为题干的意思说的就是the racer 推动 技术革新

The right answer is C. The argument mentioned nothing about the comparison between small workshop and major manufacturing corners.

The reasoning by Mindfree is correct although he made a spelling error here. C not B.

C 是答案呀：自行车赛车手的革新要求的标准没有超出通常认为以竞赛用的自行车标准。C取非，原推论就不成立。

自行车的革新都是以专业人士的要求作为标准的，那么首先我们要定义什么是专业人士要求的标准。只有在这个条件成立的情况下，推论才能成立。C就是这个假设。

讨论语法结构：

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

上句中keep应当用被动吧？sb be kept informed about...
