10. The development of a new jumbo rocket that 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 at a lower cost.
(A) The development of a new jumbo rocket that 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 at a lower cost.
(B) The development of a new jumbo rocket is expected to carry the United States into its next phase of space exploration and be able to deliver a heavier load of instruments into orbit at a lower cost than the space shuttle.
(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.

d是答案，但d选项后面的at a lower cost是不是和be able to中的be相联系呢？

LES

偶想是的，省略了be 。

cranberry

那么这个在and前面的逗号又作何解释呢？因为如果省略动词的话，就更没有理由在前面加逗号，后面的解构显得非常别扭。

LES

偶觉得这是为了结构清楚，因为than引导了一个比较从句，用“，”使at a lower cost与than引导的从句断开，更清楚地表达与主句地并列关系。

cranberry

这个解释的说服力不足，毕竟在og中，只有引入新的主语的时候才要求在并列连词前面加入逗号以免出现runon的问题，为了表示并列用逗号断开，似乎没有必要啊？而且也找不到恰当的例子来佐证。

LES

看看这题能不能作为有说服力的例子呢？

105. An inventory equal to 90 days sales is as much as even the strongest businesses carry, and then only as a way to anticipate higher prices or ensure against shortages.

(A) as much as even
(B) so much as even
(C) even so much as
(D) even as much that（A）
(E) even so much that

谢谢哦

at a lower cost.是不是应该和 deliver 对应呢？

同样作状语修饰 deliver ?
