at speeds (which are) much higher than (which)are currently possible. 我理解E选项可以理解后置定语从句作为 SVO than SVO的比较。 省略了主语which,保留动词 are。 而如果是C、D的选项: 应该是宾语Speeds的比较 at much higher speeds than those currently possible.

感觉这题真的是奇葩。一般时间不同主谓都不会省。如那道florida is XXX than it was in 18XX。 主谓都补出了。我一直认为在GMAT中than前面没时间点,后面有的话主谓补出。有时间点如florida is XXX in 2000 than in 18XX那就直接省略主谓,用作状语比较。但这题光省主语,留个are在后我真的无法理解。加上主语肯定是对的,但省略剩下个be动词连代词都没给出确实没见过。只能讲GMAT千变万化,我总结不来·
我认为的是: ...enable customers to receive internet data over regular telephone lines at speeds much higher than (customers) are currently possible (to receieve data).
从一个网上抄过来的,大家看一下
1. Use of “with” is not correct here. This gives the sense of “in addition with”. The correct idiom to use here is “at speeds”.
2. Singular verb “is” does not agree in number with plural subject “speeds”.
POE
Choice A: with speeds much higher than is: Incorrect for the reasons stated above.
Choice B: with speeds that are much higher than are: Incorrect. 1. This choice repeats the idiom error of Choice A. 2. “that are” is not needed in the sentence.
Choice C: at much higher speeds as are: Incorrect. The correct idiom is X much higher “than” Y, and not much higher “as” Y.
Choice D: at much higher speeds than that: Incorrect. Singular “that” does not agree in number with plural “speeds”.
Choice E: at speeds much higher than are: Correct.

So if "that" in D were "those", could D be an answer?
(at much higher speeds than those currently possible.)
If it could, which one is better between the modified D and E as an answer?
Also, I have a question regarding E.
Is it ok to say that "speeds" are omitted before "are" in E?
( at speeds much higher than (speeds) are currently possible.)
Thanks.
Even if Choice D had “those” instead of “that”, Choice E still would have been a better choice because “are” after than clarifies the comparison in the sentence.
The sentence says that the alliance would make the internet speed much higher than the speeds currently are. The presence of “are” makes the comparison clear between the current speeds and the speeds that will be in the future.
And yes, you are correct in saying that "speeds" is understood after "are".
