问题     The most powerful false-news weapon in history is around the corner. If technology continues its current advance, we may soon face totally convincing videos showing events that never happened—created so effectively that even experts will have trouble proving they’re fakes.
    " Deep fake" video will be able to show people saying, with the reliable ring of their own voices, things they never said. It will show them doing things they never did. In some ways, deep fake videos are no worse than rumors or false news stories. People will believe and share anything they find engaging or that reinforces their beliefs.
    But videos are more dangerous because of the authority this medium has taken on in society. For years, video has been the ultimate argument-settler. Online news outlets routinely hyperlink videos into stories to buttress the credibility of their reporting.
    Given the existing danger to truth that deep fakes present, the media industry must make its own efforts to counter the threat—and it can be effective, if it acts quickly. Right now, we have a window of opportunity in which most fake videos are far from perfect. In many cases, it’s laughably obvious that the images are manipulated. In others, fake video looks convincing to the naked eye, but technical tests can easily demonstrate that it’s a fraud. But the quality of technology we already see in the best science-fiction and fantasy movies, as well as the most sophisticated video games, shows us what will inevitably be available for broader exploitation—to far more vicious ends.
    This window gives us a chance to sound public alarms about deep fakes, promote basic tips on detecting them and immunize audiences against the better fakes to come. It’s not an impossible lift; the public is well aware of fabricated pictures and fake news stories (even if, unfortunately, they still share them) . News coverage of the dangers of deep fakes will find a ready audience.
    News companies can also publicize analytics sites and browser extensions that can alert viewers to video fakery.
    Unless the dangers of fake video receive broad public attention now, the public will be caught unaware when truly convincing fakes appear, perhaps with disastrous results.
    Finally, in publicizing the dangers, media need to avoid a tone of hopelessness—" Soon we may never know what is real and what isn’t. " Quality media outlets need to emphasize how carefully they review video. They should make sure their ethics codes and verification procedures adequately address the dangers. Otherwise, audiences will doubt any video—including legitimate and important footage that media outlets gather in their own breaking-news coverage and investigative work.
What do we learn about fake videos?
选项 A、The media industry need not take them seriously at present.
B、Most of them are far more perfect now.
C、It is hardly easy to tell whether they are artificial.
D、Some of them are persuasive at the first glance.
答案D
解析 细节题。根据第四段第四句In others, fake video looks convincing to the naked eye, but technical tests can easily demonstrate that it’s a fraud. “在其他情况下，假视频在肉眼看来很有说服力，但技术测试很容易证明这是一种欺诈行为。”可知，与D项表述一致，其中persuasive=convincing，at the first glance为the naked eye的同义改写。根据第四段第一句“媒体行业必须自己努力应对威胁”可知，与A项相反，故排除；根据第四段第二句“大多数假视频远非完美”，其中far from与B项表达相反，故排除；根据第四段第三句“在许多情况下，可笑的是，这些图像明显是被修改的。”很容易发现视频是人为操纵的，表述与C项相反，故排除。
