各位大大好！请问一道阅读题
Policymakers must confront the dilemma that fossil fuels continue to be anindispensable source of energy even though burning them produces atmosphericaccumulations of carbon dioxide that increase the likelihood of potentiallydisastrous global climate change. Currently， technology that would capture carbon dioxide emitted by powerplants and sequester it harmlessly underground or undersea instead of releasingit into the atmosphere might double the cost of generating electricity. Butbecause sequestration does not affect the cost of electricity transmission anddistribution， delivered prices will rise less， by no more than 50 percent. Research into better technologies forcapturing carbon dioxide will undoubtedly lead to lowered costs.

　　Sample Multiple-choice Questions — Select One Answer Choice
　　1. The passage implies which of the following about the current costof generating electricity?
　　A. It is higher than it would be if bettertechnologies for capturing carbon dioxide were available.
　　B. It is somewhat less than the cost of electricity transmission anddistribution.
　　C. It constitutes at most half of the delivered price of electricity.
　　D. It is dwelt on by policymakers to the exclusion of other costsassociated with electricity delivery.
　　E. It is not fully recovered by the prices charged directly toelectricity consumers.
　　Answer： C

答案没问题。不过不明白A哪里不对，不是“现在的成本比 好的技术被应用 时高”即“如果好的技术被应用，现在的成本会降低”的意思吗？
多谢多谢！

不知道是否来迟了。先看原文逻辑：（引自别的帖子）

环保技术(technology that would capture carbon dioxide emitted by power plants and sequester it harmlessly underground or undersea instead of releasing it into the atmosphere)增加一倍发电成本(double the cost of generating electricity)。环保技术不改变传输成本(the cost of electricity transmission and distribution)。最终价格(delivered prices)增加不超过50%。

最终价格=发电成本+传输成本使用环保技术后，发电成本增加了原来的一倍，但是最终价格增长不超过50%，可以得出结论，发电成本，最多占最终价格的50%。

这里的陷阱在于1。是否理解 “delivered price”: 最终成本：即 production + transmission/distribution
2. 这里讨论的 新技术 将会 that would, 说明还没有应用；一旦应用将会 double production cost。所以现在的价格当然要比“应用新技术”的价格低，而不是 higher。
