试题详情
题目：
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 wo the signals must be run through a piece of e3quiplent 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?
选项:
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 timesgreater 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 willow signals To be transmitted many times farther than at present before requiring regeneration
答案:
E
提问：
纠结A和E之间，感觉A驳斥的更彻底，直接把regenerator存在的前提fiber-optic的祖坟给刨了，E讲的是：提升regenerator的技术，让没有使用regeneration之前，传的更远。都不用regeneration了，升级regenerator的技术的意义何在呢？
是不是我想的发散了~我应该怎么往E上面靠呢？
