Choice D is the best answer. The previous question asks what the public is beginning to believe should be avoided in news stories, with the answer being the personal opinions or feelings of journalists. This is supported in lines 70-77("There...own"): "There is a growing feeling... that the news media should be 'informative rather than authoritative'; the job of journalists should be to 'give the news as raw as it is, without putting their slant on it'; and people should be given 'sufficient information' from which 'we would be able to form opinions of our own.'"
Choices A, B, and C are incorrect because the lines cited do not support the answer that the modern public wants journalists to avoid personal judgments when telling news stories, instead contrasting personal or private knowledge with public knowledge (choice A), characterizing how trusted broadcasters were once viewed (choice B), and explaining how some professional journalists feel about the new reality of the news (choice C).
