D根本上也是一个无关项目，文章已经提到fiber-optic telecommunications networks are constructed

B也是无关

只有E可以weaken，

B: Expanding its production of regenerators will require Light-line to spend proportionately more on labor and materials.

怎么不对了？正好反对

Light-line is one of the companies that will most benefit if new long-distance fiber-optic telecommunications networks are constructed.

I vote for D.

The conclusion is made based on the premise that since LL is a leading manufacturer of signal regenerators, the construction of long-distance telecommunications will benefit the company. There is an assumption that the construction of network must require using regenerators. If D is true, the assumption can’t hold any more. E is a trap. No matter how fast it is, it is still required of regenerators.

分析了很长时间，还是认为B是正确的答案

16: In recent years, networks of fiber-optic cable have been replacing electrical wire for transmitting telecommunications signals. Signals running through fiber-optic cables deteriorate, and so the signals must be run through a piece of equipment called a regenerator before being transmitted father. Light-Line is the leading manufacturer of signal regenerators. Therefore, Light-line is one of the companies that will most benefit if new long-distance fiber-optic telecommunications networks are constructed.

Which of the following, if true, casts the most doubt on the prediction about light-ling’s prospects? 注意问是否能most benefit? 如果fiber-optic 网络constructed

A: Telecommunications signals sent along electrical wires can travel much farther than signals transmitted through fiber-optic before needing to be regenerated.

B: Expanding its production of regenerators will require Light-line to spend proportionately more on labor and materials. 【简而言之，就是说成本随着产品扩大，成比例提升，说明不一定benefit】

C: The volume of signals that a fiber-optic cable can carry is several thousand times greater than the volume that can be carried by an electrical wire of similar size.   【volume不是判断是否盈利的标准】

D: There are technologies that enable telecommunications signals to be transmitted without either wire or fiber-optic cable.【是否有其他技术不一定能削弱，还需要考虑其成本等因素】

E: Several manufacturers are developing regenerator technologies that will allow signals to be transmitted many times farther than at present before requiring regeneration. 【文中并没有说明signal能被transmitted farther就代表了其优势。文中只说这个signal 被传递farther就可行】

个人认为B是比较合理的削弱答案。

支持E!这道题就是针对long-distance telecommunications 而非其它 telecommunications ！

我原本也是选E的,但是看了上面的解释,觉得B计较合理

tiandaochouqin

I think D is not the best answer, because even though there is tech. but it may not be used.

E is wrong, because they might still need the product.

so D is a better choice.

tiandaochouqin

B is also wrong because every expanding definately needs more costs, so it is not a strong point.

支持,而且更重要的是题目没有说要扩展的阿!!

支持E
