,which 一定是错的吗？

ljc0729

新东方的语法老师告诉我们碰到“，WHICH" 一定错。

大家看看下面一提

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.

1. the short flights of the shuttle and earlier spacecraft, which carried sufficient power in fuel cells and batteries[C1] 

2. the shuttle and earlier spacecraft, with sufficient enough power in fuel cells and batteries for their short flights[C2] 

3. the short flights of the shuttle and earlier spacecraft, which enabled them to carry sufficient enough power in fuel cells and batteries[C3] 

4. the shuttle and earlier spacecraft, which were capable of carrying sufficient power in fuel cells and batteries for their short flights[C4] 

5. the flights of the shuttle and earlier spacecraft, whose shortness allowed them to carry sufficient power in fuel cells and batteries[C5]

MingLiU","serif"; mso-bidi-font-size: 10.5pt; mso-fareast-language: ZH-TW;">如果按照老师的说话，那么排出A，C， D

MingLiU","serif"; mso-bidi-font-size: 10.5pt; mso-fareast-language: ZH-TW;">然后UNLIKE后面可比性原则，排出E

MingLiU","serif"; mso-bidi-font-size: 10.5pt; mso-fareast-language: ZH-TW;">所以答案是B 。

MingLiU","serif"; mso-bidi-font-size: 10.5pt; mso-fareast-language: ZH-TW;">可后来发现答案是D。 

MingLiU","serif"; mso-bidi-font-size: 10.5pt; mso-fareast-language: ZH-TW;">确实，我又仔细对比了下B， 和D。

MingLiU","serif"; mso-bidi-font-size: 10.5pt; mso-fareast-language: ZH-TW;">B的问题是用了SUFFICIENT 和 ENOUGH ，意思重复。

MingLiU","serif"; mso-bidi-font-size: 10.5pt; mso-fareast-language: ZH-TW;">而D的问题就是 ”，WHICH“，虽然从指代上来说，which  指代了shuttle 和 earlier spacecraft, 是正确的，那是不是说，WHICH的出现并不是错误答案的象征呢？

E 的the flights of shuttle 侧重的是flights 与后面的对应不上！排除A， C ，E

B,D中！B中的their 指代the shuttle and earlier spacecraft, 排除

我看还是用传统方法做！

不知大家的建议！
