OG17 紫皮书有一道题求解啊

宝宝要考tg

As a result of record low temperatures, the water pipes on the third floor froze, which caused the heads of the sprinkler system to burst, which released torrents of water into offices on the second floor.

A) which caused the heads of the sprinkler system to burst, which released torrents of water
B) which caused the heads of the sprinkler system to burst and which released torrents of water
C) which caused the heads of the sprinkler system to burst, torrents of water were then released
D) causing heads of sprinkler system to burst, then releasing torrents of water
E) causing heads of the sprinkler system to burst and release torrents of water


其它选项不用纠结，我选了D，答案说E强调了同时性，而D强调了顺序，所以E对。。。。
我想问为什么要是同时的？release确实在burst之后呀
求大神

离开CD一年多了，因为家妹备考，回来找资料，偶然看到。希望楼主此时已经豁然开朗，最好已经成功杀鸡。
正确答案是E，D／E的选择如下。

牛津英英词典 解释then是副词，而此处两个ing之间需要连词连接。就此一点，排除D
读E 由E反观可知D的表述逻辑层次上存在问题，更坚信选E不选D

以上！

D项是 "causing"和"releasing"的并列，表达的意思是“水管冻了”这个事情引起 the heads of sprinkler system to burst，然后同样“水管冻了”这个事情releases the torrents of water，主语都是水管冻了这件事情。而逻辑语义是要表达sprinkler system破裂了，导致喷出了很多水。
