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 viewsdirectlyto the public, information services present a morebalanced pictureof the complexities of political issues than any traditional news source presents.

Which of the following is an assumption on which the argument above depends?

答案C
Information on political issues disseminated through information services does not come almost entirely from advocacy groups that share a single bias.
原题已经说其他组织也用这个方法发布信息，那信息必然不是只有advocacy groups发布了，这不就与C答案所表达的意思吗

如果advocacy的信息来源是原来的途径，那自然没有什么变化了

所以c是一个前提假设
