问题                 The Question that the Bit Torrent Procedure Kindles
    Bram Cohen was an unusual kid. While other first-graders were outside playing, he was writing computer code. By junior high, he could solve Rubik’s Cube in a few minutes. A college dropout, he went on to co-found a hacker’s convention in San Francisco. " I was always really weird," he says. Yet it was only two years ago, at age 27, that he learned why. Cohen says he has trouble examining his thoughts and making eye contact but has learned to control his symptoms using behavioral psychology. Now he has a new task: warding off accusations by the Hollywood film industry that a breakthrough piece of software he wrote is threatening the movie business the way Napster menaced—and subsequently revolutionized—the music world.
    Cohen is the author of a free program called Bit Torrent, which has been downloaded more than 20 million times and underpins a new generation of file-sharing technology. BitTorrent addresses a couple of the biggest problems of file sharing—that downloading bogs down when lots of folks access a file at once, and that some people download content but refuse to share with others on the network. BitTorrent eliminates the bottleneck by having everyone share little pieces of a file at the same time—a process techies call swarming. And the program prevents leeching since folks must upload a file while they download it. All this means that the more popular the content, the more efficiently it zips through the network—bad news if you’re a movie studio trying to hinder the trading of films like The Incredibles. Says Andrew Parker of the Web-tracking firm CacheLogic, " It has turned the download world on its head."
    Hollywood has good reason to be worried. BitTorrent downloads account for one-third of Internet traffic, according to CacheLogic. So-called tracker sites post links to movies, video games and episodes of TV shows, the content of which is then traded at express speeds. With more folks logging onto the Internet via broadband connections, online trading of movies and TV shows is surging. Downloads of feature films alone are up 175% in the past year, says BigChampagne. In response, the Motion Picture Association of America (MPA[A]) recently filed dozens of civil suits against tracker sites in the U. S. and Britain, as well as criminal complaints against sites in France. The industry is hoping that in a case scheduled for next month, the U. S. Supreme Court will rule against firms that produce file-sharing software, such as Morpheus and Grokster. Neither Cohen nor BitTorrent is named in the lawsuit, although an MPAA spokesman says Cohen is under examination for continuing to develop the software "and making it easy to steal copyright material".
We can infer from the passage that______.

选项 A、Bit Torrent allows people to share files
B、the Incredibles enjoys great popularity
C、Napster lays a foundation for file-sharing
D、CacheLogic is a trader in Web download

答案B

解析 推理判断题。第二段倒数第二句指出:文件内容越受欢迎,它在网上的传递效率越高。接下来提到《超人特工队》:你要是制片厂,想阻止《超人特工队》这样的电影在网上交换,这可是个坏消息。因此可以推断出《超人特工队》是热门电影;故[B]为答案。该段首句明确指出BT是文件共享软件,[A]内容无需推断,排除;从首句可知奠定文件共享技术基础的是BT,并非Napster,排除[C];该段末句明确指出CacheLogic是网络跟踪公司,排除[D]。
