个人认为补全后是：A newly developed jumbo rocket, which is expected to carry the United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit than the space shuttle can, and( will be able to deliver them )at a lower cost.

为什么than the space shuttle can 补出的是can ,can 和be able to不是不一样的吗

答案选D，我是这样理解的。不同意的请举手！
A newly developed jumbo rocket, which is expected to carry the United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit than the space shuttle can, and at a lower cost.
which 是rocket的非限制性定语从句。
比较的对象是rocket(will be able to)和space shuttle (can)。
并列的对象是 will be able to deliver... 和 (will be) at a lower cost，主语都是A newly developed jumbo rocket

I wanna share my thoughts here. It's easy to reach answers D and E.
At first blush, I found E lacks "can" after SS, so I think the sentence is ambiguous since it means either 'JR will be able to deliver a heavier load of instruments into orbit than the space shuttle [will be able to do]' or ''JR will be able to deliver a heavier load of instruments into orbit than [deliver] space shuttle'.However, it's common sense that space shuttle is a kind of vehicle to deliver instrument rather than instrument itself. Thus, the lack of "can" should not be a split as long as the sentense is not ambiguous.
OK, once I can not find determinate error among choices, I have to think about the meaning of these sentences. Because the original sentence seems not to say the JR cost less, but to say the delivery cost less. Therefore, answer D is fit.
Note: keep the meaning of answer as that of original sentence. This is rule of thumb which hasn't verified by GMAT, but works well  till now. Manhattan also advocates this rule

以下是引用bluestone1在2003-12-7 23:00:00的发言： 我来试一下  A newly developed jumbo rocke ...

可不可以是 than the space shuttle can deliver ....  than后面是不是应该句子是完整的？and后面只是状语比较。而且能不能将and看成是递进的？

小小明噢耶

Mark一下！
