Q21. The proper way to plan a scientific project is first to decide its goal and then to plan the best way to accomplish that goal. The United States space station project does not conform to this ideal. When the Cold War ended, the project lost its original purpose, so another purpose was quickly grafted onto the project that of conducting limited-gravity experiments, even though such experiments can be done in an alternative way. It is, therefore, abundantly clear that the space station should not be built.
The reasoning in the argument is flawed because the argument
(C) Faults planners for not foreseeing a certain event, when in fact that event was not foreseeable. (E) Concludes that a shortcoming is fatal having produced evidence only of the existence of that shortcoming.
The answer is E but I cannot think out why C is not right.
C不是答案, 因为原文并没有指责planner failed to predict the end of Cold War. 原文的逻辑是:做一个project, 要先找出goal, 然后再找到实现goal的最佳途径. 太空站用于研究失重不是经过这个planning process,所以太空站不应该建立 (隐含意思:太空站不是最好的途径). 所以E是答案, 因为存在一个弱点, 就说这个弱点是致命的. 举一个简单的例子说明:正常的任命过程是由500名代表选举出最合格的人选, 现在由president任命了A, 所以不应该选A(意思是A不是最合格的). 逻辑上的错误就是由一个缺陷否定了大前提.
