Cable-television spokesperson: Subscriptions to cable television are a bargain in comparison to "free" television. Remember that "free" televi-sion is not really free. It is consumers, in the end, who pay for the costly advertising that supports "free" television.

Which of the following, if true, is most damaging to the position of the cable-television spokesperson?

(A) Consumers who do not own television sets are less likely to be influenced in their purchasing decisions by television advertising than are consumers who own television sets.
(B) Subscriptions to cable television include access to some public-television channels, which do not accept advertising.
(C) For locations with poor television reception, cable television provides picture quality superior to that provided by free television.
(D) There is as much advertising on many cable-television channels as there is on "free" tele-vision channels.
(E) Cable-television subscribers can choose which channels they wish to receive, and the fees vary accordingly.

答案：D，我不明白D为什么是削弱？

引用mindfree大师的经典回答

读问题, 知道是weaken类型. 并且是weaken cable provider (因为有时原文有两种意见,所以要清楚是weaken哪个观点或理论).

读原文. 第一句(A), 读完知道是应该是一个结论. 有时会有两个以上的结论, 分为sub-conclusion和conclusion. sub-cobclusion都应该服务于final conclusion. Premises和assumption可以分别支持sub-conclusion和conclusion. (我说得很啰唆, 在做题是一般不用去区分sub和final, 读懂题自然就知道了)

读完第二句 (B), 知道这也是一个conclusion, 或是sub-conclusion. 意思上明显是支持第一句.

读完第三句 (C), 知道是一个premise, 支持第二句.

这样, 读完原文就知道其逻辑推理过程: consumers pay for advertising (C) --> free TV not cheap (B) --> cable is a bargain (A). 还要知道所牵涉的事物: advertising, TV, cable, COST

weaken题型有很多类型, 可以否定原文的依据, 如:没有或有不多advertising, 或advertising已经不costly, 或者不是consumers pay for advertising. 这种题都是直接针对premises, 否认其真实性或可靠性, 其它的例子还有否定问卷调查的结果 by questioning the objectivity or representativeness of the survey.

还有一种类型是否定原文的assumption. 例如此题. 如果问题是cable provider的assumption是什么, 答案是? 就是D的一部分: cable service没有同类的consumers要pay for的advertising. 如果这个assumption(必要条件)不成立, 原文结论不成立.

同理, 此题答案也可以是cable service的某一特点约等于free TV的advertising. 也是否定assumption.
