22(Z) Political advocacy groups have begun to use information services to disseminate information that is then accessed by the public via personal computer. Since many groups are thus able to bypass traditional news sources, whose reporting is selective, and to present their political views directly to the public, information services present a more balanced picture of the complexities of political issues than any traditional news source presents.
Which of the following is an assumption on which the argument above depends?
A. Information services are accessible to enough people to ensure that political advocacy groups can use these services to reach as large a percentage of the public as they could through traditional news sources.
B. People could get a thorough understanding of a particular political issue by sorting through information provided by several traditional news sources, each with differing editorial biases.
C. Information on political issues disseminated through information services does not come almost entirely from advocacy groups that share a single bias.
D. Traditional news sources seldom report the views of political advocacy groups accurately.
E. Most people who get information on political issues from newspapers and other traditional news sources can readily identify the editorial biases of those sources.
d选项为什么不对呢？我觉得d说传统的报道都不准确，取非正好说传统的报道都很准确，不是削弱了原来的说法？ 另外，假设题可以用取非削弱的方式验证，这样验证时候的选项取非之后如果是直接说原文的现象或结论不对算不算削弱呢？ 小菜鸟，求助各位高人了

你理解的有偏差。“很少”并不代表 “都不”
可以用选项取非，原结论不正确的方式来验证。D取反，题目的结论依然可以成立，所以D不是前提。
要注意結論的特殊性
因為題干結論不是在談論報道的accruate，而是報道反映的政治觀點的balance，因為不同的voice不會被傳統媒體給過濾掉了。
此外，即使information services 的報道也不一定是accruate的。
所以D項是無關項目。
