难道E不可以认为是这样省略吗：The cost of running nuclear plants is about the same as (the cost of running )other types of power plants,
CD里面一些帖子认为是加for 像正确答案Ｂ一样 The cost of running nuclear plants is about the same as for other types of power plants,
OE说：E选项中The preposition for is necessary in the comparison of the costs.
