19. Every student who walks to school goes home for lunch. It follows that some students who have part-time jobs do not walk to school. The conclusion of the argument follows logically if which one of the following is assumed?
(A) Some students who do not have part-time jobs go home for lunch
(B) Every student who goes home for lunch has a part-time job.
(C) Some students who do not have part-time jobs do not go home for lunch.
(D) Some students who do not go home for lunch have part-time jobs.
(E) Every student who goes home for lunch walks to school
Ans. D
does everone have short-cut to generalize such question?
The stable functioning of a society depends upon the relatively long-term stability of the goals of its citizens. This is clear from the fact that unless the majority of individuals have a predictable and enduring set of aspirations, it will be impossible for a legislature to craft laws that will augment the satisfaction of the citzinery, and it should be obvious that a society is stable only if its laws tend to increase the happiness of its citizens.
The claim that a society is stable only if its law tends to increase the happiness of its citizens plays which one of the following roles in the argument?
a. It is the conclusion.
b. It helps to support the conclusion
c. It is a claim that must be refuted if the conclusion is to be established
d. It is a consequence of the argument
e. It is used to illustrate the general principle that the argument presupposes.
why is C rather than e?作者: tongxun 时间: 2002-10-1 01:32
19、它问的前提是：some students who have part-time jobs do not walk to school成立的前提。由于前面已经表明了，每个，（是每个）走到学校的都回家吃饭。因此，some students who have part-time jobs 是不回家吃饭的。这部分人占不回家吃饭人的一部分，因为没有part-time jobs 而车来车望的人也有可能不回家吃饭。所以， Some students who do not go home for lunch have part-time jobs。只能是some！
象这样的题目，有95%以上的答案，要找有单词some的。选项的话不能说绝。
另一题：
因为它与为解释结论而提出的论据：from the fact that 后的it will be impossible for 相矛盾，因为他也是结实结论的论据之一，两个相矛盾的论据放在一起必定会导致结论的不成立。作者: schwa995 时间: 2002-10-1 10:34
