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

这个选项虽然是最佳的，但是from前是不是有，会更好？因为它应该是non-essential的吧。。。
谢谢大家啦：）

没看懂lz什么意思？是说如果from 放在前面会更好吗？？

逗号不能加。因为这里from...to....和reduce 连用，意思是把T型车的组装时间从一天半减少到93分钟。
