看一题为什么...'s 要比 ....of...要好

Spanning more than 50 years, Friedrich Muller began his career in an unpromising apprenticeship as a Sanskrit scholar and culminated in virtually every honor that European governments and learned societies could bestow.
(A) Muller began his career in an unpromising apprenticeship as
(B) Muller’s career began in an unpromising apprenticeship as
(C) Muller’s career began with the unpromising apprenticeship of being
(D) Muller had begun his career with the unpromising apprenticeship of being
(E) the career of Muller has begun with an unpromising apprenticeship of
OG中解释说E的the career of Muller要比B中的 Muller’s career要好。
不是以前有一道题the ability of French 要比French's ability 好吗

B Correct. Using Müller’s career as the subject
of the sentence solves the modification
problem with spanning … and provides a
logical subject for culminated.



这是OG对于B的解释，请问LS是问的这个解释不清楚还是？我认为所有格用的没问题啊此处，Muller是人，所以我认为所有格和of结构都可以，问题不大
