C.

我在E和C之间纠结 为什么不选E 过去完成时呢 谢谢
因为题目逻辑意思没有明确指示这个MINERAL EXTRACTION并没有在过去某个时间段就停止了,题目只是说25年前才知道原来是习惯在这过程中担当了重要作用,并没说这种MINERAL EXTRACTION停止了.
根据文章的逻辑意思,这种方法很有可能现在还在使用
所以E不对
弱问~~~
LZ这个GWD是哪个版本的?是GWD-TN24嘛?还是?。。。。
回LS,是TN24。另想问下D选项错在哪了?

个人觉得as early as the eighteenth century是修饰整个主句动词发生的但D中变成修饰后面名词,而且有指代不清的嫌疑,是method 呢还是mineral呢?
E中完成时态不好,but 后的句子才一般过去时那还是25年前,发生在前半句时间的后面。而且感觉well established as early as the eighteenth century后置修饰对象比较模糊,意思也有变

哦~有道理 THX
B的错误十分明显,
第一,前半句话没有谓语
第二,同位语应紧跟被修饰名词。
