[原创]a brand new GWD sc

a brand new GWD sc, thanks, CD

According to analysts, an alliance between three major personal computer companies and most of the nation's largest local telephone companies would enable customers to receive Internet data over regular telephone lines with speeds much higher than is currently possible.

A. with speeds much higher than is
B. with speeds that are much higher than are
C. at much higher speeds as are
D. at much higher speeds than that
E. at speeds much higher than are

why E? why not D? the "are" is weird, open to discussion

"are" is related with"Speeds".than (the speeds) are ...

How new is the GWD you mentioned ?     

B 为什么不对啊？

比较的speeds，than后面省略的是（speeds that） are

但为什么把much higher放在speeds后面呢？我就是因为这个才选d的

应该是E，

首先，at speed应该是比较习惯的用法；

其次，d中的that无所指

再次，（speeds that） are省略了speeds that
