There is nowhere in early American literaturewhere the influence of Jane Austen is so apparent as thenovels of James Fenimore Cooper.

A Thereis nowhere in early American literature where the influence of Jane Austen isso apparent as

B Inearly American literature, nowhere is Jane Austin's influence so apparent thanin

C Itis nowhere more apparent in early American literature that Jane Austen was aninfluence as in

D Nowherein early American literature is the influence of Jane Austen more apparent thanin

E Nowherein early American literature is it more apparent that Jane Austen had aninfluence than

这道题正确答案是D，但是我当时选的是B，然后选项的解释是这样的：in early Americanliterature是修饰nowhere的，这里变成了修饰整句使得逻辑错误；so…than错误。先不管so...than的用法，我只问前面的解释，in early American literature 为什么不能修饰整句话呢而是修饰nowhere的呢？
求牛牛解释~谢谢~
