The growth of the railraods led to the abolition of local times, which was determined by when the sun reached the observer's meridian and differing from city to city, and to the establishment of regional times.

E. determined by when the sun reached the observer's meridian and differing

正确答案是E,划线部分错在哪里呢？

我刚刚做过这题。

local times似乎用单数不太妥当，E很聪明地采取了回避的办法；

而且，determined by和differing都是被动语态或者分词形式，修辞local times，如果是原句的话and differing接着的是which was，似乎省略也有问题。

不知道说清楚了没有哦。
