The first trenches that were cut into a 500-acre site at Tell Hamoukar, Syria, have yielded strong evidence for centrally administered complex societies in northern regions of the Middle East that were arising simultaneously with but independently of the more celebrated city-states of southern Mesopotamia, in what is now southern Iraq.
(A) that were cut into a 500-acre site at Tell Hamoukar, Syria, have yielded strong evidence for centrally administered complex societies in northern regions of the Middle East that were arising simultaneously with but
(B) that were cut into a 500-acre site at Tell Hamoukar, Syria, yields strong evidence that centrally administered complex societies in northern regions of the Middle East were arising simultaneously with but also
(C) having been cut into a 500-acre site at Tell Hamoukar, Syria, have yielded strong evidence that centrally administered complex societies in northern regions of the Middle East were arising simultaneously but
(D) cut into a 500-acre site at Tell Hamoukar, Syria, yields strong evidence of centrally administered complex societies in northern regions of the Middle East arising simultaneously but also
(E) cut into a 500-acre site at Tell Hamoukar, Syria, have yielded strong evidence that centrally administered complex societies in northern regions of the Middle East arose simultaneously with but


该题答案为E,经查询曼哈顿论坛，发现有人提出"...with but" just does not seem right. Can someone please give me another example of this use. 对此也感到很是疑问，文中的实际意思我认为应理解为共同发生但是相互独立，但是通常but 表示转折关系。对此Ron 解答为：you're not separating this construction at the correct place. it's a parallel structure, with two prepositional constructions, separated by "but also":simultaneously with
...but also...
independently of

看完后更加困惑，因为只有在not only ....but also里      also可以省略掉，但句子前面并没有，这里怎么体现的平行关系而不是转折关系呢？求解

JaeYoong

平行关系包含了并列（and), 选择（or） 和 转折（but）

but语法结构上跟and一样要求平行，只不过逻辑关系上表示转折

Joehe2010

simultaneously with是同时发生
but independently of独立于
按照awa的模板就是，这两件事情同时发生但是有没有因果关系的

非常感谢
