SC倒装句 过去分词放句首 后面需要加逗号吗

A labyrinthine system was so intricately designed and constructed in the Egyptian Pyramid that even Nakhti, the chief architect, could not find his way out.

其他的选项，我就不写了，就是这个选项它的解释，我觉得不是很明白。

E Designed and constructed so intricately in the Egyptian Pyramid was a labyrinthine system that

E is incorrect. The inverted subject "a labyrinthine system" correctly agrees with the auxiliary verb "was". The past participle modifiers "designed and constructed" are placed at the beginning of the sentance, so there must be a comma before the subject.

为什么要有都好在subject前面啊，我查了好多语法书都完全没有写这一点。麻烦各位指点一下。谢谢
