### HideShow timer Statistics

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-lingâ€™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.

I'm going with E.

A: Telecommunications signals sent along electrical wires can travel much farther than signals transmitted through fiber-optic before needing to be regenerated. - IRRELEVANT. conclusion is - 'Light-line is one of the companies that will most benefit if new long-distance fiber-optic telecommunications networks are constructed'

B: Expanding its production of regenerators will require Light-line to spend proportionately more on labor and materials. - SO? This does not mean that it will not benifit.

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. - IRRELEVANT.We are only bothered about whether Light Line will benifit or not.

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

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

If these manufacturers succeed, Light-line can go bankrupt.
