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.
我认为从结论的具体性和特殊性来说E是不能削弱的,如文中结论说的Light-line is one of the companies that will most benefit if new long-distance fiber-optic telecommunications networks are constructed. 而E就是在重复结论嘛
