D

A than B 结构中, A与B的性质应相同. Development与space shuttle性质不同不并列. Del A, B, C选项.

E选项的"(be able) to cost less"非习惯用法. Del E

我选C。

选D。 C 不对，"development" cant "deliver". what is the key?

qww

dansy说的对，应该是D。

根据主语，答案肯定在D，E中。
换个问题：I'm able to run faster than you can. or , I'm able to run faster than you.

Hey, 750? don't panic the public:-)

I choose D for the following reasons?
1, Logically,  it is the rocket rather than development that delivers instruments into orbit. A,B and C are eliminated.
2, It's unidiomatic to say "be able to cost". First, "be able to" represents an ability, "rocket" doesn't have the ability. Second, you don' twant to say "My new CD player was able to cost me $100." On the contrary, you want to say "My new CD player cost me $100."
3, D is good because it has a "can" which , in most cases, is perferred by ETS.
