答案有问题？？

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
   
2. the shuttle and earlier spacecraft, with sufficient enough power in fuel cells and batteries for their short flights
   
3. the short flights of the shuttle and earlier spacecraft, which enabled them to carry sufficient enough power in fuel cells and batteries
   
4. the shuttle and earlier spacecraft, which were capable of carrying sufficient power in fuel cells and batteries for their short flights
   
5. the flights of the shuttle and earlier spacecraft, whose shortness allowed them to carry sufficient power in fuel cells and batteries
   
   
   各位大神帮忙看看~答案是D which were 怎么样也不会说的通吧~你们说呢 我好想选A呀 各位大神认为呢~

A里面主语是short flights啊，跟space station比不对吧

这道题我也迷眼了，迷失了方向，看了manhattangmat的帖子才知道缘故
根据sufficient enough不能一起表达的原则，BC排，在ADE中选
A. the short flights of the shuttle and earlier spacecraft, which carried sufficient power in fuel cells and batteries---主语是the short flights and earlier spacecraft和a permanently orbiting space station不平行，应该是shuttle/spacecraft和a permanently orbiting space station才平行

符合条件只有D符合，所以D对

见参考：http://www.manhattangmat.com/forums/sc-unlike-the-short-flights-of-the-shuttle-and-t8034.html

Unlike还是没有吃透，要能够应付千变万化的情况啊

问一下，B中with的用法

我查了很多地方，GMAT中with的考点是什么啊？这道题，如果sufficient enough不重复的话，with的用法对吗？？

unlike前后对比的事物必须具有可比性，要属于一类事物。

后面的名词是a permanently orbiting space station，那么unlike中对应的名词应该是shuttle和spacecraft，而不是short flights。所以A不对。

而且which were没有啥说不通的啊，which代指shuttle和spacecraft，是复数，而且都说了earlier了，说明那是过去的东西了，现在可能不用了，所以用were没有问题吧我觉得

求助
我也很好奇为什么which这里的用法
看以前ron说 which只能修饰紧挨的名词 或者 名词加介词短语
能修饰前面A AND B 一个整体吗
