大家讨论一下吧...

A: were謂語重複，應該去掉

B: correct，connected分詞修飾句子主語settlements

C: 第二個of修飾Structures不對，應該修飾scale；each同位語從句用過去完成時沒必要，

D: 第二個of修飾Structures不對，應該修飾scale；and with each沒有平行物件，

E: 第二個of修飾Structures不對，應該修飾scale；each後面是完整句子但沒有連詞

AS WELL AS既可以做连词，也可以做介词。以上题目中应该做介词，所以后面可以跟ING形式。如SHE SINGS AS WELL AS PLAYING THE PIANO.当然你把它当连词用并列形式也没错，但主要看选项有没有other obvious mistakes.
