标题: 再问天山3-7

T-3-Q7.

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.

number of wild salmon have been reduced because of uncontrolled deep-sea and coastal netting
number of wild salmon is reduced because deep-sea and coastal netting is not controlled
numbers of wild salmon has been reduced because of uncontrolled deep-sea and coastal netting
wild salmon’s numbers are reduced by deep-sea and coastal netting that is not controlled
wild salmon’s numbers have been reduced by uncontrolled deep-sea and coastal netting.

答案是E，看了以前的帖子，说B当中的第二个is->are，而且和后面未划线部分的..by…, and by不对称。

后者我没意见，但是至于单复数的问题，个人意见，deep-sea and coastal netting 是两个形容词（deep-sea ，coastal）修饰一个中心名词netting，谓语应该用单数阿。。。望指教！！
