GWD 9-7 坛子里没人关注过的问题

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.

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

GWD答案 E  

我认为是 D

理由：

1) by pollution, and by various other threats to the fish’s habitat. 说明前面是个并列成份，如果选E, 就应该是

by uncontrolled deep-sea， by coastal netting, by pollution, and by various other threats to the fish’s habitat.

2)deep-sea与coastal对应（深海和近海）同时修饰 netting，为了明确这点D中定语从句用is来说明前面是一个复合名词

我搜了 9-7 没有找到反对E的意见，但是我认为把uncontrolled deep-sea和coastal netting并列是错误的。

请大家关注并发表意见。

i think E is correct.

Wild salmon can net either in deepsea or in coast
