天山3-20 （没人问过，是不是只有我错了？汗）

Leaching was a well-established method of mineral extraction (c)
                had been a method of mineral extraction, well eatablished (e)
as early as the 18th century

我放弃c，选择e是认为未划线部分的 as early as 是修饰eatablished的
这个接在c后面有点怪怪的

请nns指教

E eatablished 修饰extration，而他原本应修饰method

MM说得是，谢谢
不过我还想问问，C里面的as early as 应该怎么理解呢？

半个月前的GWD明明选对了，怎么今天就看走眼了呢。

还是错过的题目印象深刻。
