OG13 SC49 一个关于同位语成分的新问题 请NN指教

Hugateddybear

49. The automotive conveyor-belt system, which Henry Ford modeled after an assembly-line technique introduced by Ransom Olds, reduced from a day and a half to 93 minutes the required time of assembling a Model T.

(A) from a day and a half to 93 minutes the required time of assembling a Model T

(B) the time being required to assemble a Model T, from a day and a half down to 93 minutes

(C) the time being required to assemble a Model T, a day and a half to 93 minutes

(D) the time required to assemble a Model T from a day and a half to 93 minutes

(E) from a day and a half to 93 minutes, the time required for the assembling of a Model T

其实对这个题目的选项是如何选择的已经理解。但是对E中的逗号有一个问题。
og对E的解释中包含一句话： the comma is unnecessary。这是为什么呢？ the time required for the assembling of a Model T做的是什么成分呢？是前面时间的同位语吗？为什么不需要逗号？

请NN帮忙解答一下 谢谢

其实这道题要明白一个点就可以啦，看一下这两句：reduce the time  from a day and a half to 93 minutes 和 reduce  from a day and a half to 93 minutes, the time...对吧，og说的comma的多余，是由于介词短语的位置awkward导致的，fron介短插入的使用所以才多用了一个comma，而正常来讲我们是直接使用reduce the time from.....就可以了，所以这里还是介词短语位置的awkward的问题，而不是comma的问题，即：reduce the time from.....优于reduce from....,the time
