renown by renown for 有什么区别

(C.G Jung,a Swiss psychologist,whose renown as a pioneer) in the field of psychoanalysis almost equals that of Sigmund Freud

whose引导的定从修饰的是逗号前得那个单词,如果不改,则这个单词是psychologist,而很多人都可以是psychologist.文中想说的却只是c.g.jung,所以括号里的有歧义,不好.

括号内的哪里错了呢?不是做后置定语么?如果错了应该改成什么?

为什么括号内的要改成　this　fact　explains　why　so　many　high　school　students．呢?原句有什么错呢?
原句有歧义,explaining的逻辑主语优先选择主句的主语（high school graduates）,但显然explaining实际上修饰的是前面的整句.用this fact这个抽象名词代替前面的整句是修饰整句常见的方法.
