求助prep07-1 第一次看到主谓宾后面跟三个长修饰><

小瓶子

1. The Anasazi settlements at Chaco Canyon were built on a spectacular scale with more than 75 carefully engineered structures， of up to 600 rooms each，were connected by a complex regional system of roads.
（with more than 75 carefully engineered structures， of up to 600 rooms each，were 划线 ）
A. with more than 75 carefully engineered structures， of up to 600 rooms each， were

B. with more than 75 carefully engineered structures， 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 and with each

E. of more than 75 carefully engineered structures of up to 600 rooms each had been

A: were谓语重复，应该去掉

B: correct，connected分词修饰句子主语settlements

C: 第二个of修饰Structures不对，应该修饰scale;each同位语从句用过去完成时没必要，

D: 第二个of修饰Structures不对，应该修饰scale;and with each没有平行对象，

E: 第二个of修饰Structures不对，应该修饰scale;each后面是完整句子但没有连词

注意：

1、The Anasazi settlements at Chaco Canyon were built on a spectacular scale of up to 600 rooms each， connected by a complex regional system of roads. each指The Anasazi settlements，而不是rooms或者structures!

2、介词的修饰对象、插入语、逗号+过去分词的用途及修饰对象

按照答案的解释 of of up to 600 rooms each这个是修饰settlements，
connected 也是修饰settlements ,
这么长，隔得这么远的修饰不会引起歧义么？

谢谢！！

of up to 600 rooms each是插入语，不影响。connected是修饰structures的吧，CDE都是语义错了，过去完成时也不对
