[求助]prep里的SC题 - ChaseDream

The Anasazi settlements at Chaco Canyon were built on a spectacular scale with more than 75 carefully engineered stuctures, of up to 600 rooms each, were connected by a complex regional system of roads.
A. with more than 75 carefully engineered stuctures, of up to 600 rooms each, were
B. with more than 75 carefully engineered stuctures, of up to 600 rooms each,
C. of more than 75 carefully engineered structures of up to 600 rooms, each that had been
D. of more than 75 carefully engineered structures of up to 600 rooms amd with each
E. of more than 75 carefully engineered structures of up to 600 rooms, each had been

我觉的subject of "connect"应该是each,过去分词一般都是就近修饰。

同时each应该作为独立主格，对engineered stuctures起到解释作用。

我觉得C,D,E不对是因为each指room,改变了原意，可是除此之外，of和with是都可以的吗？

而A不对是因为用were的话connect和built的就平行了，这样subject就是The Anasazi settlements，可是我觉得从逻辑上主语是settlements好像也没什么问题。是不是即使要平行的话，就要加and所以A不对呢？

不过我始终觉得这个句子怪怪的，是不是省略了什么部分？把省略的补全应该是怎样呢？

answer: B

I want to know what is the subject of "connect"?

而且我觉得scale的话，用of 不是更好吗？

大家忙帮忙讲一下，谢谢~

The subject of "connect" is 600 rooms. "each" is an adverb here indicating "more than 75 carefully engineered structures".

大家指教~

A 不对：未划线部分已经是个完整的句子了，不能再补充were，而且each应该对应单数。

btw我还是觉得connected修饰each
