182, 用 in convincing 后一句不就变成了修饰前句吗? 那会变成修饰错误，因为做convincing的是谁? 是campaign不是The organic food industry。

208， produced not BY A but BY B, 考点为平衡，答案只有一个。算是惯常用法，记着吧

208.    (26425-!-item-!-188;#058&001968)    (GWD-11-40)

Scientists who studied the famous gold field known as Serra Pelada concluded that the rich lode was （开始划线not produced by the accepted methods of ore formation but that swarms of microbes over millions of years划线完毕） concentrated the gold from jungle soils and rivers and rocks.
A. not produced by the accepted methods of ore formation but that swarms of microbes over millions of years
B. not produced by the accepted methods of ore formation but instead swarms of microbes over millions of years that
C. not produced by the accepted methods of ore formation but swarms of microbes over millions of years that
D. produced not by the accepted methods of ore formation but by swarms of microbes that over millions of years
E. produced not by the accepted methods of ore formation but that swarms of microbes over millions of years
选D，我想问下C为啥不行，
1.not produced by the accepted methods of ore formation but( produced by ) swarms of microbes over millions of years that，是对的吧
2.而且that，which不是也可以跳过over millions of years修饰microbes，之前有些题目是可以这样的。
3.原句里面的 over millions of years不是在that从句里面的，选项D是在that从句里的，不会改变修饰么？
谢谢
