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.
Teresa's point is about the economical disadvantage about manned spaceflight. 也就是说，spaceflight花钱太多了，相比于其他飞行方法。
Edward's point is about safety.
Edward didnt address the point that is claimed by Teresa.
C) completely wrong. nothing outweights another. E's and T's point are completely different.
D) Correct. E assumes no impedement, but teresa raised this impedement as costs. E didnt address the issue.
E) the argument is not about priority...作者: sprite112 时间: 2011-10-9 20:49
