gre argument 205题目：
The following appeared in a recommendation from the president of Amburg's Chamber of Commerce.
"Last October the city of Belleville installed high intensity lighting in its central business district, and vandalism there declined almost immediately(1). The city of Amburg has recently begun police patrols on bicycles in its business district(3) but the rate of vandalism there remains constant. Since high intensity lighting is apparently the most effective way(4) to combat crime(7), we should install such lighting throughout(6) Amburg(2,5). By reducing crime in this way, we can revitalize the declining neighborhoods in our city(8)."
提纲：
(1)The president unfairly assumes that it is the installation of high intensity lighting that resulted in the decline in vandalism in Belleville.
(2)Belleville and Amburg might not be comparable at many aspects.
(3)The author fails to point out in what places do most vandalism at Amburg take place, thus we cannot evaluate if the police patrols are ineffective.
(4)The president ignores many other effective ways to combat crime.
(5)The president fails to consider the cost of installing high intensity lighting throughout Amburg and if we could afford it.
(6)Granted that installing such lighting could reduce vandalism, the necessity of installing the lighting all over Amburg is open to doubt.
(7)Granted that installing such lighting could reduce vandalism, we cannot guarantee that it would deter other types of crimes since vandalism is not the only type of crime in Amburg.
(8)The president unfairly assumes that the proposed actions would sufficiently guarantee revitalization of city neighborhoods.
