大全-3-18. 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.
(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.

怎么会选择D呢，C不是正确的吗？reliability比省钱更重要吗！各位看看你们都选什么？！谢谢

先说D为什么对——
先答yes:文中T的观点是assumes that there is no serious impediment to transporting people into space
E的观点是有一impediment。所以给出 It does not meet Teresa’s point 是对的。
反过来答no，显然与文中相反，削弱。
再说你认为的C安全和经济的先后顺序是你自己的感觉，文中从来都没有说有这样的assumption。你可以再看看D，D也只是说他做出了assumes。
