The Nobel Prize in chemistry was awarded to three scientists for their discovery that plastic can be

made electrically conductive--an advance that has led to improvements in film, television screens,

and windows.

(A) that plastic can be made electrically conductive--an advance that has led

(B) that plastic can be made electrically conductive--this advance leading

(C) that plastic can be made to be electrically conductive, and this advance led

(D) of plastic's ability to be made electrically conductive, with this advance leading

(E) of plastic being able to be made electrically conductive--an advance that has led

B选项后面this advance leading...为何不能理解为独立主格呢？

an advance是对前面的discovery的内容的一个概括，而this advance意思感觉像是前面已经出现了advance这个名词，然后this来个指代，而前文并没有出现advance。

再一个就是leading不能表达出has led的含义

我的理解哈，看看有木有帮助~

当然如果理解为同位语的话因为同位语不能用特指所以this advance肯定是不对的；但是this advance做独立主格补充说明整句话又怎么说呢？

我记得独立主格N+分词。。。这种形式和主句的逻辑关系是不紧密的，但这里明显就是对主句内容进一步的描述。。所以我觉得用独立主格不太好额

对哦，独立主格要和原文没有太大的关系，有道理！
谢谢啦！
