gwd13-29, 我选E

13-Q29:
For protection from the summer sun, the Mojave lived in open-sided, flat-topped dwellings known as shades, each a roof of poles and arrowweed supported by posts set in a rectangle.

A.each a roof of poles and arrowweed
B.each a roof of poles and arrowweed that are being
C.with each being a roof of poles and arrowweed
D.with roofs of poles and arrowweed to be
E.with roofs of poles and arrowweed that are

答案是A, 我选E. supported by posts set in a rectangle.
应该修饰roofs, 必须用定语从句才能修饰到roofs.

A选项each a roof of poles and arrowweed supported by posts set in a rectangle, supported 只能修饰到arrowweed.

请问大家的选择?

Thanks, LES!

这个不太确定，请NN们发表意见，谢谢先！

但是，E选项的明显错误是roofs与后面的set in a rectangle逻辑搭配错误。

A: a roof supported by..

E the verb tense is wrong. The whole sentence uses the past tense,while E use the present tense, which is inconsistent with the whole sentence.
