[单选题]阅读理解
A1. Technological progress has made possible such surveillance control methods that looked fantastic a couple decades ago: satellites, electronic chips, Internet databases, so on. However, the progress goes faster than the society is able to accept the novelties, thus conflicts regarding privacy the rightfulness of control methods can arise. One of the most debatable issues at current is whether or not surveillance through security cameras has negative effects on the public.Though the so-called crime cameras have proved themselves to be an effective tool for fighting street organized crime, concerns about their wide use still remain. Nancy La Vigne, the director of Chicago’s Justice Policy Center, says that camera systems are often believed to be violating citizens’ constitutionally-protected right to privacy when they are used to identify non-lawbreakers. Though there are rules limiting cameras’ possibilities, how can one be sure that they are not watched, that these rules are observed? Surveys show that about 23% of US citizens tend to believe that security cameras violate their privacy.The opponents of surveillance also stress the fact that security cameras can evoke negative emotions in citizens, make them feel being constantly watched controlled. This refers both to adults, who already have an established system of views on the state, the government, the society, the children, who are in a process of developing such a system. Stated succinctly, children may believe that the state has a right to interfere in private lives of its citizens, that being under control surveillance is a norm.In a nutshell, though surveillance cameras are meant to help to protect citizens from street organized crime, are an effective tool of monitoring, there exist several issues concerning privacy ethics.21. In the third paragraph, the underlined phrase “such a system” refers to____.A.the system of security cameras
Bthe system of views on the state, the government, the society
Cthe system of one’s emotions
Dthe system of surveillance
