问gwd21的一道语法题

Q5:给的答案是C，可是which不就指代前面的句子了么？那A为什么不对呢？

There are no legal limits, as there are for cod and haddock, on the size of monkfish that can be caught, a circumstance that contributes to their depletion through overfishing.

1. There are no legal limits, as there are for cod and haddock, on the size of monkfish that can be caught, a circumstance that contributes to their depletion through overfishing.
2. There are no legal limits on the size of monkfish that can be caught, unlike cod or haddock, a circumstance that contributes to depleting them because they are being overfished.
3. There are legal limits on the size of cod and haddock that can be caught, but not for monkfish, which contributes to its depletion through overfishing.
4. Unlike cod and haddock, there are no legal size limits on catching monkfish, which contributes to its depletion by being overfished.
5. Unlike catching cod and haddock, there are no legal size limits on catching monkfish, contributing to their depletion because they are overfished.

   Answer:

不会，感觉which像指代there are no legal limits for monkfish这句话，但是这是不合理的阿

顶起来！

I would choose A.

B, D, E unlike比较对象应该对乘

C，我觉得which  refers to "monkfish"， 所以变成monkfish contributes to its depletion through overfishing. 逻辑不对。。。

以上为个人观点
