PREP08 209
209. (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,

C项解释
C.  the numbers错误(MANHATTAN SC上提到：Never select an answer choice containing the phrase THE NUMBERS OF)；and平行错误同A

下文又提及

6)    the number (s) of + 名词单数或者复数 + 动词单数或者复数，表示标号，数字标识

这时number是核心词，number、物品、谓语动词三者的单/复数形式要一致

The numbers of the machine parts A and B are respectively 201 and 203.

机器零件A和B的标号分别是201和203。

派生出The number of machine part A is 201.     

这时number与numbers互为单复数的关系。注意，这里。

The numbers of the machine parts are not available. 这些机器零件的号码找不到了。

此两处不矛盾吗？
请牛牛指教！

the number of 表示数量肯定是用单数；下文提及的the numbers of 是表示标号数字标识，这两者不是一回事，所以不矛盾
