18.   Teresa: Manned spaceflight does not have a future, since it cannot compete economically with other means of accomplishing the objectives of spaceflight.

Edward: No mode of human transportation has a better record of reliability: two accidents in twenty-five years. Thus manned spaceflight definitely has a positive future.

Which of the following is the best logical evaluation of Edward’s argument as a response to Teresa’s argument?

(A) It cites evidence that, if true, tends to disprove the evidence cited by Teresa in drawing her conclusion.

(B) It indicates a logical gap in the support that Teresa offers for her conclusion.

(C) It raises a consideration that outweighs the argument Teresa makes.

(D) It does not meet Teresa’s point because it assumes that there is no serious impediment to transporting people into space, but this was the issue raised by Teresa.（D）

(E) It fails to respond to Teresa’s argument because it does not address the fundamental issue of whether space activities should have priority over other claims on the national budget.

Why C is not correct???

I see.

But why D is correct?

我是不明白为什么e不对：（

1.关键弄懂两个短语的内涵：D的serious impediment 是技术问题还是经济问题？原文的objectives of spaceflight指什麽。D的后半句话说this was the issue raised by Teresa，而原文T提的问题是economically，所以这个serious impediment 是指经济问题（即经济问题成为大障碍）。对于D来说，这个objectives of spaceflight是指transporting people into space。

2。弄懂了两个短语的内涵，便明白D为何正确。E提的理由是spaceflight可靠性好，从而得出spaceflight有好的前景（在完成载人任务方面），它没考虑经济因素，假设了spaceflight不会贵得离奇（在作为交通工具方面）。而这个问题恰恰是T在考虑的。

3。E错的原因是：T的基本问题是将spaceflight和别的交通工具比经济那个合算，E却是和别的预算项目比优先性。out of scope

谢谢lawyer-1班主的详细解答！

可我不知为什么，总觉得spaceflight和别的交通工具比经济那个合算与spaceflight和别的预算项目比优先性好像意思差不多阿？核算的经济不就是预算小吗？我也不知道自己钻到哪个牛角尖里了！：（

I know, thanks!!！

(C) It raises a consideration that outweighs the argument Teresa makes.

Edward以“可靠性”判定manned spaceflight有前途，Teresa以“不经济”判定manned spaceflight无前途。

请问：可靠性是不是outweigh经济性？也就是说在完成太空项目中可靠性是不是要比经济性更重要？

(D) It does not meet Teresa’s point because it assumes that there is no serious impediment to transporting people into space, but this was the issue raised by Teresa.

请问：① 按照常理，将人送入太空的serious impediment是技术还是钱？② Edward认为其它方式的可靠性都有问题，不就是说Edward认为将人送入太空这件事上还是存在重大阻碍的么？

根据以上对C和D的理解，我认为应该选C。D中serious impediment如果按照常理来理解将导致D的表述错误，而C符合逻辑。

请NN讨论！
