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.
(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
原文意思：说一个建筑物建筑规模比较宏大，有75个structure，有600多个room并且和各种道路相连
题目分析：A有不止一个谓语，were built是一个后面的were connected是另外一个，干掉。
B前面用with后面用of up，形成并列关系表示建筑物的两个特点进行并列，还可以，留着。
C后面的of up to 600 rooms变成修饰structure了，这个of短语应该修饰scale的，语义不对，干掉。
D犯的错误和C类似，干掉。
E又是相同错误，干掉！
