还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
整个句子的意思：查克峡谷的Anasazi居住地建造的规模宏大，有超过75个复杂的工程结构，每个工程结构都有超过600个房间，所有的工程结构之间由复杂的区域路径连接起来。
with表伴随用来进一步解释和补充spectacular scale（怎样的规模宏大？内部包含超过75个工程结构）。
connected with each other是作为modifier修饰structures的，所以不能加were。正确B
【补充】analogy:
the USA comprises 50 states, each of which is united by a federal government --> wrong (the implication is that each state has its own federal government)
the USA comprises 50 states, all of which are united by a federal government --> correct
the USA comprises 50 states, (all) united by a federal government --> correct, whether you have 'all' or not
