OG Diagnostic Test 43题求助

43.  Despite the increasing number of women graduating from law school and passing bar examinations, the proportion of judges and partners at major law ?rms who are women have not risen to a comparable extent.
(A)  the proportion of judges and partners at major law ?rms who are women have not risen to a comparable extent
(B)  the proportion of women judges and partners at major law ?rms have not risen comparably
(C)  the proportion of judges and partners at major law ?rms who are women has not risen comparably
(D)  yet the proportion of women judges and partners at major law ?rms has not risen to a comparable extent
(E)  yet the proportion of judges and partners at major law ?rms who are women has not risen comparably
这个题官方的解释是如果这样说“the proportion of women judges and partners”,这样women只形容了judges，为什么他用了从句的形式就不是只修饰parnters呢？
同理困扰我的还有这个题：
49.  As an actress and, more importantly, as a teacher of acting, Stella Adler was one of the most in?uential artists in the American theater, who trained several generations of actors including Marlon Brando and Robert De Niro.
(A)  Stella Adler was one of the most in?uential artists in the American theater, who trained several generations of actors including
(B)  Stella Adler, one of the most in?uential artists in the American theater, trained several generations of actors who include
(C)  Stella Adler was one of the most in?uential artists in the American theater, training several generations of actors whose ranks included
(D)  one of the most in?uential artists in the American theater was Stella Adler, who trained several generations of actors including
(E)  one of the most in?uential artists in the American theater, Stella Adler, trained several generations of actors whose ranks included
官方解释是这个who必须放在Stella Adler后面，不在后面就可能误解为修饰theater。这题和下面上面的题都矛盾！
同样作对比的还有这个题：
50.  By developing the Secure Digital Music Initiative, the recording industry associations of North America, Japan, and Europe hope to create a standardized way of distributing songs and full-length recordings on the Internetthat will protect copyright holders and foil the many audio pirates who copy and distribute digital music illegally.
(A)  of distributing songs and full-length recordings on the Internet that will protect copyright holders and foil the many audio pirates who copy and distribute
(B)  of distributing songs and full-length recordings on the Internet and to protect copyright holders and foiling the many audio pirates copying and distributing
(C)  for distributing songs and full-length recordings on the Internet while it protects copyright holders and foils the many audio pirates who copy and distribute
这道题我又迷糊了，为什么这里的that就是形容way而不是形容internet呢？
盼高人指点！！！
