In several cities, the government is going ahead with ambitious construction projects despite the high office-vacancy rates in those cities. The vacant offices, though avaliable for leasing, unfortunately do not meet the requirements for the facilities needed, such as court houses and laboratories. The government, therefore, is not guilty of any fiscal wastefulness. Which of the following is an assumption on which the argument above depends? 正确答案：Adaption of vacant office space to meet the government's requirements, if possible, would not make leasing such office space a more cost-effective alternative to new construction. 对文意的主旨不甚理解，望高人点拨。
263. Many state legislatures are considering proposals to the effects that certain policies should be determined not by the legislature itself but by public referenda in which every voter can take part. Critics of the proposals argue that the outcomes of public referenda would be biased, since wealthy special-interest groups are able to influence voters' views by means of television advertisements. Which of the following, if true, most strengthens the critics' argument? 正确答案：Proponents of policies that are opposed by wealthy special-interest groups are often unable to afford advertising time on local television stations. 我的答案：Television stations are reluctant to become associated with any one political opinion, for fear of losing viewers who do not share that opinion. 个人感觉，正确选项只表明那些利益团体控制了传媒，而并没有表明传媒会对大众产生影响。 而我选的选项，似乎更能表现传媒对大众的影响力。作者: 2008115061 时间: 2010-8-15 22:39
