QUARTZ7

In Scotland, the number of wild salmon have been reduced because of uncontrolled deep-sea and coastal netting, by pollution, and by various other threats to the fish’s habitat.


A. number of wild salmon have been reduced because of uncontrolled deep-sea and coastal netting,  





B. number of wild salmon is reduced because deep-sea and coastal netting is not controlled,






C. numbers of wild salmon has been reduced because of uncontrolled deep-sea and coastal netting,





D. wild salmon’s numbers are reduced by deep-sea and coastal netting that is not controlled,





E. wild salmon’s numbers have been reduced by uncontrolled deep-sea and coastal netting

注意看未划线的 by pollution, and by various other threats to ..  by的发出者是谁，
可以由此排除A,B,C


为什么因此就可以排除ABC呢
这样的说法不对吗？the number of wild salmon has been rduced by uncontrolled deep-sea and coastal netting.
必须要说成：wild salmon's numbers have been reduced by uncontrooled deep-sea and coastal netting吗？谢谢啦

我读到这里也有这个疑问 虽然这个题可以考平行做 但不是很理解Prep08里对这个“by pollution的逻辑承受者应该是wild salmon的解释 所以ABC错”的解释。
求教！谢谢！！！

这道题目的NUMBER太TRICKY了

There are two things, we need to fix.

First: SV agreement:

A number of -> plural

The number of  -> singular

Second: Parallelism: because remaining text is having structure...by pollution, and by various other threats to the fish’s habitat. " uncontrolled deep-sea and coastal netting" must also have by before it. Hence it must be "by uncontrolled deep-sea and coastal netting"

A. number of wild salmon have been reduced because of uncontrolled deep-sea and coastal netting-----> SV is wrong, parallelism is not there.
B. number of wild salmon is reduced because deep-sea and coastal netting is not controlled  ----> Here SV is okay, parallelism is not there.
C. numbers of wild salmon has been reduced because of uncontrolled deep-sea and coastal netting  ---> wrong usage of numbers, parallelism is not there.
D. wild salmon’s numbers are reduced by deep-sea and coastal netting that is not controlled ---> SV is okay, "deep-sea and coastal netting that is not controlled" is unnecessarily verbose and modifies only netting. Also "that" modifier is also not parallel in remaining part of the sentence.
E. wild salmon’s numbers have been reduced by uncontrolled deep-sea and coastal netting --- SV is okay and perfectly parallel.
