Q1:

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.

1. with speeds much higher than is
2. with speeds that are much higher than are
3. at much higher speeds as are
4. at much higher speeds than that
5. at speeds much higher than are

答案是E。我对于这个are有些疑惑。much higher than是用来修饰speeds的，而speeds是一个宾语。宾语的比较记得是不用加动词的。。如果E是at speeds much higher than those currently possible是不是更好些呢？谢谢！
