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.
我理解题目是：问A在论证中犯的错误。
读完选项后，觉得一个都不对。

我觉得选B.jane 的结论是减少看电视的时间，alan的结论是不用限制看电视。正如b所说他说结论本身是错误的，其实削弱就可以了。

谢谢1stzhang
但还是不懂，
指出A的论证错误，要和A的论证过程相关，但是B中看不出来，哪位大侠把B翻译一下。谢谢

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）。

讲的透彻。

讲得好。
