Unlike the short flights of the shuttle and earlier spacecraft, which carried sufficient power in fuel cells and batteries, a permanently orbiting space station will have to generate its own electricity.
A. the short flights of the shuttle and earlier spacecraft, which carried sufficient power in fuel cells and batteries,
B. the shuttle and earlier spacecraft, with sufficient enough power in fuel cells and batteries for their short flights,
C. the short flights of the shuttle and earlier spacecraft, which enabled them to carry sufficient enough power in fuel cells and batteries,
D. the shuttle and earlier spacecraft, which were capable of carrying sufficient power in fuel cells and batteries for their short flights,
E. the flights of the shuttle and earlier spacecraft, whose shortness allowed them to carry sufficient power in fuel cells and batteries,
这个题目我选了B，答案是D
谁能帮我分析一下呢？是不是B的with夹心了，既可以修饰前面，也可以修饰后面的？还有sufficient 和ebough是不是算重复呢？
这是我在知道答案之后分析的原因，不知道对不对？
1.sufficient和enough不能同用
根据The Columbia Guide to Standard American English的解释，enough同sufficient的区别为：
As an adjective sufficient almost always sounds stiffer and more Formal than enough.Use either sufficient or enough, depending on the level you seek, but don’t use both together, as in This flour is sufficient enough for today’s baking. Sufficient is sufficient. Enough’s enough.
2.与B相比，D选项更能与“..space station will have to generate its own electricity”在逻辑含义上平行，对比两者产能方式及能力，表达更准确清楚。
3.由于B中"with.."里含有their,因此不能修饰“a permanently orbiting space station”，不是错误点。
个人拙见，望NN们多多评点指教～
不会吧……D的时态对吗：which were capable of carrying sufficient power in fuel cells and batteries for their short flights
