While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity.
(A) While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to
generate electricity.
(B) While the cost of running nuclear plants is about the same as for other types of power plants, the fixed costs that stem from building nuclear plants make the electricity they generate more expensive.
(C) Even though it costs about the same to run nuclear plants as for other types of power plants, it is the fixed costs that stem from building nuclear plants that makes the electricity they generate more expensive.
(D) It costs about the same to run nuclear plants as for other types of power plants, whereas the electricity they generate is more expensive, stemmingfrom the fixed costs of building nuclear plants.
(E) The cost of running nuclear plants is about the same as other types of power plants, but the electricity they generate is made more expensive because of the fixed costs stemming from building nuclear plants.
别的错误点不谈，咱们只说比较对象的问题：我认为A选项比较对象平行it costs about the same to run nuclear plants as （to run）other types of power plants省略了to run，但是比较对象平行；B选项 While the cost of running nuclear plants is about the same as（the cost） for other types of power plants,省略了the cost，但是比较对象平行；C选项it costs about the same to run nuclear plants as（to run） for other types of power plants 中for多余，所以比较对象不平行；D选项同C，for多余，所以比较对象不平行；E选项The cost of running nuclear plants is about the same as（the cost of running） other types of power plants, 省略了the cost of running但是比较对象平行。大神们帮我看看我分析的对不对？？感激不尽！！！

E不平行：cost 和 那什么相同，其他都是省略
