3。The growth of the railroads 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.
A.同题中
B。which was determined by when the sun reached the observer's meridian and which differed
c.which were determined by when the sun reached the observer's meridian and differing
D.determined by when the sun reached the observer's meridian and differed
E。determined by when the sun reached the observer's meridian and differing
解释：
Choice D presents a false compound: determined is an adjective modifying local times and differed is the simple past tense ofto differ.（不平行） Because they serve different grammatical functions, these words cannot be treated as parallel elements joined byand。

我的问题是：我可以理解为 D 中的 determined 和 differed 都是过去分词表被动，一起来修饰local times  啊，为什么不对呢？总觉得differing 不对啊，differ 不是总是用被动语态吗？求点拨啊！ 谢谢啦！！

看到你写的是D，还以为我选错了，还好选对了。其实，这道题，我没有那么复杂的分析： local times 是被确定于（determined by)...而 时间变化是自己本身发生的事情，用主动：differing。--考了小逻辑上的问题。这道题，在OG12中的42题也有体现，好好品味OG12的42题，对你这种题有帮助。

Thank you for your supplement, got it !

是differ from A to B无werediffered的说法，differ自己其他搭配有were differed的书法，比如differ A from B可以有被动语态，完毕！

恩恩 ~简言之： D 中 determined 是过去 分词， 而 differed 无 were differed 的说法（无被动说法），所以排除了 differed 做分词的形式，那么只剩下 differed 做 过去式了。

最简单解释就是differ from A to B中的differ无法变成被动语态，所以当它加ed，只能是一般过去时中的一般过去式形态，而不是过去分词，所以无法和determined这个过去分词平行
