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.

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.

这道题答案是E,但我对如何排除B,C选项不是很理解，因为我理解deep-sea and coastal是修饰netting的，这样就可以理解成单数。还是我理解错了deep-sea和coastal netting是两个并列的原因？但是the salmon's numbers are reduced by uncontrolled deep-sea从语义上说应该是不通的吧

恳求大师指教，万分感谢。

B选项的错误主要要看未划线部分，如果没有后边的by pollution, and by various...，B按照楼主的方式也可以勉强算对，但加了后边的这部分后说明用了词组be reduced by，此时要注意前后平行，不能用because
C选项的错误在于the numbers of sth.这种表述是错误的，manhattan里有明确指出，即便算对，the numbers是复数，主谓不一致
