求指教！og18-762 starfish的题

Starfish, with anywhere from five to eight arms, have a strong regenerative ability, and if one arm is lost it quickly replaces it, sometimes by the animal overcompensating and growing an extra one or two.

A one arm is lost it quickly replaces it, sometimes by the animal overcompensating and
B one arm is lost it is quickly replaced, with the animal sometimes overcompensating and
C they lose one arm they quickly replace it, sometimes by the animal overcompensating,
D they lose one arm they are quickly replaced, with the animal sometimes overcompensating,
E they lose one arm it is quickly replaced, sometimes with the animal overcompensating


答案选B
og上的解释有说D的错误是 The conditional clause has a active verb, while the result clause has a passive verb.
那是否意味着在gmat里面，if 和 then 句子的主动被动语态要前后一致？

个人理解：

我做的时候也是没有发现passive和active的区别，但我也排除了其他选b。

谢谢～看来以后可以多一个解题突破点了～

觉得d的错误在于they are quickly replaced. 这里的they应该是说arm, 前面 if they lose one arm，后面跟着就来个they来指代one arm，指代的错误同时造成了语态的错误。而且，compensating 后面有个逗号，导致后面的growing修饰前面整句话，不对。我觉得如果d改成they quickly replace it，再把后面的逗号去掉，那d就对了，语态和代词都没问题。

如果你对照一下b的话，你的问题的答案应该就很明显，是的。
