研究快一个小时这道题。。。还是不很理解、、、求剖析~~~
28. 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.（KEY）

(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.

Premise:
1) Innovation in bike is limited by consumer demand.
2) The only cyclists seriously interested in innovation and willing to pay for it are bicycle racers.

Conclusion:
Innovation in bicycle technology is limited by what authorities will accept as standard for purposes of competition in bicycle races.

Logic chains:
1) Innovation in bike --> limited by consumer demand (A --> B)
2) Consumers who demand and pay for innovations --> bike racers (B--> C)
3) Innovation in bike --> limited by standard set by authorities for bike races (A --> D)

If you connect the dots, the assumption has to be C --> D, which is "Bike racers --> standard set by authorities for bike races."

Now check all the answer choices for the one that is the closest to C --> D.

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

C) fits the bill.

LS大神啊~我还是班门弄斧一下算了~因为我也好不容易搞懂~
其实第一句话是没什么用的
第二句讲的是只有那些职业自行车手才对自行车的创新感兴趣
第三局是结论说自行车的创新被政府的标准限制
这中间就有一个gap
就是自行车手和政府的标准的关系
C选项意思是自行车手对不在政府标准里的创新不感兴趣（assumption）
