(C) The new development of a 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 at a lower cost than the space shuttle.
(D) 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.
(E) 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 and to cost less.
我选了E,觉得够平行
答案D?

这是OG的题目？这么熟悉。
答案D。
deliver ..heavirer......and .........at a lower cost

答案E "than the space shuttle"没补充谓语动词CAN ，应而不如D好。

thanks
发现这个can果然重要，不然有歧义

首先县可以排除ABC，因为句子主语是jumbo rocket，而不是development，de中d的表达比e更明确

好题

补充buleeyes，

最后的and at a lower cost是个省略结构，OG中有类似的结构，好像说的是一个independent company提供service的，最后也是省略了前面的谓语部分。

发现 CD 的人回答帖子的热情倒是很高啊！
但是错误并不是因为省略一个can，而是要明了and at a lower cost/ and cost less 的细微差别！


二者省略的地方和省略了什么是最重要的
E：and to cost less （than the space shuttle ）
D：的表达是正确的，和火箭比能带的更多，（和火箭比[运东西]）花费更少。要不就成了制作的费用比火箭少了。

D) 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 a load of instruments ]at a lower cost.

E是不对的:will be able to cost less 是不和逻辑的！D的意思就是一个省略相当于do so at a lower cost起一个补充说明的作用！
