Journalist: Some critics argue that as the entertainment value of news reporting increases, the caliber of that reporting decreases. Yet the greatest journalists have been the most entertaining. So these critics are mistaken. The journalist's conclusion is properly drawn if which one of the following is assumed? ['The greatest journalists have been entertainers who report the news.', 'The news reporting of the greatest journalists has been of the highest caliber.', 'Journalistic greatness involves producing news that is very valuable in some sense.', 'Entertainment and news are not mutually exclusive categories.']
