[求助]GWD7-Q20彻底晕了...

GWD7-Q20:

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

答案是E，我彻底不明白题说什么，也看不出语法点...帮帮我啊...

A. "...Middle East that were arising simultaneously" is wrong:  "complex societies" is rising, not "Middle East"

B. D: "But also" needs "Not Only". They should be in a pair.

c: "...having been cut" is wrong.

谢谢啦~

在S的TH地方挖出来的500英亩的沟，极力地证明了，中央集权社会在 中东的 北部地区 与更为著名的城邦 南美索不达米亚（现在的南伊朗） 同时但是独立地 出现了。

bd一眼看出谓语用的是yields，主语是trenches，所以bd上来就可以排除；

c也很容易排除，一般看到having been done开头的句子，在gmat语法中都不是prefer的，作为正确答案的概率极小；

ae比较，明显发现e比a好

就因该是-ed分词和限定性从句的区别了吧

cut应该是一次性具体动作吧,那应该用从句的呀?

但E:evidence that同位语从句因该是优选

晕~这个...
