问题     Police in the popular resort city Virginia Beach recently began operating video surveillance cameras with controversial face recognition technology. Virginia Beach and Tampa in Florida are two cities in the United States to acquire the technology, which cost it $197,000. "Before we switched it on, we went through an extensive public education process with hearings and the involvement of citizen groups and minority groups, who helped write the policies we are using," said deputy police chief Greg Mullen. A citizens’ auditing committee has the right to perform unannounced spot checks on police headquarters to make sure the technology is not being misused.
    Three of the city’s 13 cameras are linked full-time to the face recognition system, though the others can be activated as needed. The database of wanted people is updated every day. So far, the system has failed to produce a single arrest, though it has generated a few false alarms. It works by analyzing faces based on a series of measurements, such as the distance from the tip of the nose to the chin or the space between the eyes. Critics say it is highly inaccurate and can be easily fooled. Mullen, who sees the system eventually being linked to the databases of other city, state and federal law enforcement agencies to track criminals and suspected terrorists, said, "The system doesn’t look at skin color or your hair or your gender. It takes human prejudices out of the equation. "
    "This technology has little or no effect on the crime rate but it does have an effect on people’s behavior. People feel cowed," said Bruce Steinhardt, who directs a technology. Despite the fact that tests have shown face recognition only works in around 30 percent of cases, the ACLU is alarmed that the technology may soon spread to airports. The organization also fears it could potentially be used to monitor individuals’ political activities to harass law-abiding citizens.
    "This kind of surveillance should be subject to the same procedures as wiretaps. Law enforcement agencies should justify why they need it and it should be tightly limited, otherwise it will soon become a tool of social control," said Mihir Kshirsagar of the Electronic Information Privacy Center. Nor does such criticism come exclusively from the political left. Lawyer John Whitehead, founder of the conservative Rutherford Institute, wrote in an editorial that the technology threatened the right of each U. S. citizen to participate in society. "After all, that is exactly what constant surveillance is—the ultimate implied threat of coercion," he wrote.
Mullen’s statement in Paragraph 1 indicates that
选项 A、police is confident in using the technology.
B、police has made preparation for the use of the technology.
C、citizens have rights over managing the technology.
D、police has gone through public education process.
答案B
解析 第一段中马伦的话表明，[A]警察在使用这项技术时很有信心。[B]警察已经为这项技术的使用做了准备。[c]公民有权管理这项技术。[D]警察已经进行了公众教育。文章第一段第三句马伦的话指出，他们使用监控摄像机之前通过听证会对广大民众进行了教育，公民群体和少数派群体也参与了这项活动，并帮助书写了他们正在使用的方案。这说明警察局对这项技术非常谨慎，广泛听取了公民的意见，为监视摄像机的使用做了充分准备。因此，正确答案是[B]。[A]不正确，因为警察局对这项技术非常小心，可见他们对这项技术也不是很有信心；我们无法从马伦的话中推断出[C]“公民有权管理这项技术”．[D]与马伦的话无关。
