19. Jane: According to an article in this newsmagazine, children’s hand-eye coordination suffers when they spend a great amount of time watching television. Therefore, we must restrict the amount of time Jacqueline and Mildred are allowed to watch television.
Alan: Rubbish! The article says that only children under three are affected in that way. Jacqueline is ten and Mildred is eight. Therefore, we need not restrict their television viewing.
Alan’s argument against Jane’s conclusion makes which one of the following errors in
reasoning?
(A) It relies on the same source that Jane cited in support of her conclusion.
(B) It confuses undermining an argument in support of a given conclusion with showing that the conclusion itself is false.
(C) It does not address the main point of Jane’s argument and focuses instead on a side issue.
(D) It makes an irrelevant appeals to an authority.
(E) It fails to distinguish the consequences of a certain practice from the causes of the practice.
B.为什么对呢?
看了以前总结的对19题的分析,还是不理解,请哪位大虾再指点一下吧!原来分析如下:
j的前提是长时间看电视会损坏孩子的眼手协调,结论是要限制两个孩子看电视。
而a回答是对前提的质疑(范围),即不是所有的孩子而是仅在一年龄段的才会受此影响。因此并不是反对结论本身,而是将削弱支持结论的论述confuse成了指出结论本身错误(B)。
A回答中有两部分:1)质疑前提;2)指出两个孩子不属于前提所说范围,并结论说“no need to restrict their television viewing"。 这句话既可以理解为不限制他们看电视,也可以理解为看电视的时间也都不限制。 那也就是很明确的反对了J。不能说没有反对J的结论。 |
