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.
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.
the key:C
恳请牛牛讲解一下，另外其他的选项该如何快速排除，望指点。谢谢

123 Advertisement: Today’s customers expect high quality. Every advance in the quality of manufactured products raises customer expectations. The company that is satisfied with the current quality of its products will soon find that its customers are not. At MegaCorp, meeting or exceeding customer expectations is our goal.

(A)MegaCorp’s competitors will succeed in attracting customers only if those competitors adopt MegaCorp’s goal as their own.

(D)If a company becomes satisfied with the quality of its products, then the quality of its products is sure to decline.

还是想问一下有关选项排除的问题。

1. First you need to understand the argument and its reasoning. Assumption is to fill the "gap" between premises and conclusions. So the meaning of the assumption must be relevant to the argument. To test assumption, use negative and see if original argument still holds or not.

A. Irrelevant. The argument is not about whether the market can expand or not. And cheap and high-performance are not mentioned. Use A negative you can see original argument does not change.
B. Irrelevant. It does not fit in the argument at all.
C. Right. The gap in the original argument is that the premises said that innovation is driven by racers and conclusion is that innovation is limited to just a certain type. There is a gap between "racer" and certain innovations. Let me use an analogy:

Computer software sales are driven by teens. So software development is limited to games. The gap is between teens and game. The argument by default associate one with the other, in another word, by assumption.

C is just the statement of the association.
D. Irrelevant. It is a whle new statement, which is not substantiated by the original argument.
E. If you truly understand the meaning of E, you would not pick it. Another irrelevant choice.

我在这两天的总结过程中发现虽然问的是conclusion，但是实际上就是再问assumption&inferrence.也就是说可以用取非的假设做法来做conclusion的题，不知这种感觉对否。曾经和一位斑竹讨论过这个问题，这位斑竹的回复是：assumption是支持的真子集，可是不是归纳的。您看呢？谢谢

网上下载的123题发现与122题重复，能否将OG对于123题的解释一并贴上来，谢谢！

Mindfree关于桥梁型假设题解释的真经典！

我做这题使用取非削弱来做的，可见两种方法是可以融会贯通的。(以前一直认为两个方法是孤立的，一个题只能用一种方法解)

建议后来的朋友把这些化石贴认真读了，比直接实时问要来的好。毕竟在某一个特定时刻不会集中比过去这些大牛更多的牛人。

办法就是遇到问题，搜索出来都读了。有重点大牛的重点读。

这个解决后，按照大牛ID搜索出来，拜读。

Highlight出来的意思是不是, 碰到问题先搜索, 若有比较好的NN解释, 再按照NN的ID搜索拜读? 是个好方法! (不过, 还要看时间和问题的针对性)

谢谢Andrea625

对了,忘了问有些是NN的参与贴,用ID搜索不出来的吧?

应该排除这种可能性.

想问一下楼主的第二题。

刚刚开始研究CR，也刚刚开始用去非这个办法，怎么越用越

请教，C取非的话是只要取非主句吗。

取非了就变成MegaCorp’s goal is not possible to meet only if continuing advances in product quality are possible.
然后再怎么想呢，有点转不过来。。。
