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?

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.

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.

D: There are technologies that enable telecommunications signals to be transmitted without either wire or fiber-optic cable.

E: Several manufacturers are developing regenerator technologies that will allow signals to be transmitted many times farther than at present before requiring regeneration.

答案选  E  但是我选  B

谢谢指点

B不通阿, 如果大家都生产regenrator的话, 就算投入多点的labor和materials, 那家现在的leading manufacturer还是赚的最多的阿.

而且文章没哟说要扩张的哦

我觉得E是不对的，它强调的是before requiring regeneration，而且说是让信号传得更快而已，不管传得多快，最终还是要经过regenerator，这样E选项对于那家公司以后的前景没有起到削弱的作用，但是B选项说要生产regenerator要花很多其他的成本，因为就算所有的regenerator都是Light-line生产的，但是它的成本也很高，因此对这间公司来说，并不是非常有利的，这样就对它的prospects有削弱作用。

hehe， 楼上的MM， 这里的farther是更远的意思，是far, 不是fast的比较级。B中扯的有点远了，而且就算真需要扩产，那也是一次性投资，而不影响厂家获益。

再说，哪个厂家不希望扩产啊。。。那是因为有生意啊。

E.

New regenerators will service same distance with less regenerators, thus will hinder the need for regenerators, in turn will hinder the profit for Light-Line.  This innovation goes against Light-Line.

B.

To produce more regenerators will require more labor and material cost is almost a prerequisite to increase output for all such companies.  This does not go against light-line.

注意结论说的是if...前提是需要R，新技术好，可以befor....已经不在前提里啦

Which of the following, if true, casts the most doubt on the prediction about light-line’s prospects?

 

A.    Telecommunications signals sent along electrical wires can travel much farther than signals transmitted through fiber-optic before needing to be regenerated. 否定的位置不对，原文前提已经说fiber-optic比wires快

B.    Expanding its production of regenerators will require Light-Line to spend proportionately more on labor and materials.
        重点不是在L公司的其它花费上面，也有可能利益和花费同等增加

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. 没否定反而小小支持

D.    There are technologies that enable telecommunications signals to be transmitted without either wire or fiber-optic cable. 否定的位置不对
        完全否定了前提的必需条件
        是偏掉了的否定
        不对

E.     Several manufacturers are developing regenerator technologies that will allow signals to be transmitted many times farther than at present before requiring regeneration. 直接站在regeneration的点上，把利益在使用regeneration前就被打断，使得L公司的利益不可能↑
