问题     In the U.S., citizens tend to rely on electronic media such as TV rather than print media. TV news tends to provide numerous visuals and abbreviated textual information.【T1】Although TV news stories pitch "on-the-scene reporting," and other eye-catching images to viewers, the actual stories are generally so brief that were the reports transcribed into newspaper copy, no single story would have enough text to cover a third of a page. It is remarkable to consider how little information is conveyed between all the exciting visuals. 【T2】It is also remarkable to stop and think about how inadequately informed citizens may be if their primary source of political knowledge is the picture-rich and data-poor TV evening news.
    Moreover, because U.S. media companies are primarily privately   owned, 【T3】media professionals are under pressure to present news in an entertaining way in order to expand their audiences and corresponding advertising revenues. Large audiences create higher profits from advertising sales. With a few exceptions, U.S. TV and radio stations are like other businesses: They need to generate money to cover operating costs and make profits. If media professionals are convinced that viewers want entertaining news rather than in-depth details, this assumption affects the kind of news they produce. Not surprisingly, political scientists have found that news coverage of election campaigns tends to focus on the personal lives of candidates rather than on issues, and【T4】when issues are reported the emphasis is often on the immediate and most dramatic implications of the issues, not on the historical, long-term, or global dimensions of those issues.
    At the same time, insofar as television and Internet-based news must be generated quickly, time pressures impede extensive independent investigations. Because U. S. citizens conceptualize news as something occurring by the hour or minute, U.S. media professionals are often putting together news stories under severe time restraints. 【T5】Some analysts believe that this increases the tendency of reporters to get information from official sources rather than from the reporters’ own independent investigations of newsworthy events. Think about this issue from the standpoint of reporters and editors. If you are a reporter assigned the task of doing a story on a state’s new prison system, for example, you will find it is quicker and easier to get a governor’s press release on the new prison than it is to go to libraries, data banks, and university research centers to investigate the topic on your own. This does not suggest that investigative journalism never occurs; rather, many scholars believe that time pressures tend to encourage the use of information provided by official sources (for example, political leaders and their press secretaries) rather than the collection of facts through ongoing independent research.

选项
答案也有必要停下来思考一下：如果公民的政治知识的主要来源是图片丰富而资料贫乏的电视晚间新闻，那么他们的知识面可能会有多窄?解析：该句的It是形式主语，真正的主语是后面的不定式短语。另外，remarkable(异常的，引人注目的)一词可以被理解为“值得注意的，有必要的”。
