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 farther. 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-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.
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.

Premise 1: Trends: networks of fiber-optic cable are replacing networks of electrical wire.
Fact 1: Signals deteriorates when run through fiber-optic cables , therefore, regenerator must be installed before being transmitted farther
Premise 2: Light-Line is the leading manufacturer of signal regenerators.
Conclusion: Light-Line is one of the companies that will most benefit if new long-distance fiber-optic telecommunications networks are constructed.
Question: Weaken the conclusion.
Prethinking: How will the company Light- Line most benefit from fibre optics networks? Probably when all the fibre optics networks have regenrators from Light Line?
A. Telecommunications signals sent along electrical wires can travel much farther than signals transmitted through fiber-optic before needing to be regenerated. This is negating the Premise1 ...So wrong answer choice
B. Expanding its production of regenerators will require Light-Line to spend proportionately more on labor and materials. 1) Does the company actually require to expand it production? It is not clear. .2) Even if Light Line is expanding its production and is spending more on labor and materials then also we can not say surely that Light Line will not be benefited from the construction of fibre optics network because the more the demand of Regenration equipment will lead to greater income of Light Line.
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. Un necssary informationuc
D. There are technologies that enable telecommunications signals to be transmitted without either wire or fiber-optic cable. Hmm, there could be advanced technologies present. But in this argument, we are only concerned about fiber optic cable. So this is out of scope.
E. Several manufacturers are developing regenerator technologies that will allow signals to be transmitted many times farther than at present before requiring regeneration.
Light- Line: Present regeneration equipment can let say transmit upto 10km.
New Manufacturers: Developing regeneration equipment that can let say transmit upto 15km.
New technology can increase the distance MANY TIMES before the Light Line equipment is installed. Therefore, it could reduce the orders that the Light Line would get otherwise(in absence of this technology) and hence this could reduce the Light Line revenue. So, this weakens the conclusion and hence the Answer.
