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

答案E，错选了D……
实在不明白这里的are是作为什么出现了……（speeds）are currently possible?
还有这里的speeds后面是加复数verb的吗……那如果D中的that改成those呢？
求解……谢谢……

than可以作为准关系代词，看做 than (the speeds which)
因为speeds是复数，所以补出are
如果改成those个人感觉不太好，后面如要要改建议前面一半改成定语后置（当然，这样从比较结构来说也比较好）
