我覺得B是對的 因為它跟獲利(benefit)最有關係 因此最能反駁結論
to spend proportionately more on labor and materials


D: There are technologies that enable telecommunications signals to be transmitted without either wire or fiber-optic cable.
題目已說if new long-distance fiber-optic telecommunications networks are constructed 因此這是無關選項


E: Several manufacturers are developing regenerator technologies that will allow signals to be transmitted many times farther than at present before requiring regeneration.
訊號能夠傳送更遠是無關的 因為並不代表訊號不會惡化
是訊號的品質影響L公司能不能獲利 而非訊號的距離

D超出了文章的范围，最后一句说 if ....fiber-optic....are constructed.

分析了很长时间，还是认为B是正确的答案Which of the following, if true, casts the most doubt on the pr ...

Labor and materials are not the only input in manufacturing regenerators, other factor, for example logistics, will also account to the total cost! B should be crossed out!

问啊问啊

做的时候B确实犹豫过，觉得增加了成本并不表示不能benefit，现在看来当时的想法是对的。

之所以选E，是忽略了了结论中的 one of the company，私以为E选项其实说的是，有不止一个公司都有可能获益，是从限定范围角度反驳了结论，one of or not one of，而不是从这些公司会抢LL公司的饭碗的角度考虑的
