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
这题别的解释都是牵强,凭什么which就比with好,只要语义正确就行了。 看看Native speaker的解释 two things to add:
(1) sufficient + enough is REDUNDANT. redundancy is very bad. same reason you wouldn't say "reply back", "added bonus", or "determined as a result of" (see #138 in OG11, if you have that).
(2) make sure you know that "enough THAT" is incorrect. the 2 idioms mentioned above are correct.
