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 within a month. The city of Amburg has recently begun police patrols on bicycles in its business district, but the rate of vandalism there remains constant. We should install high-intensity lighting throughout Amburg, then, because doing so is a more effective way to combat crime. By reducing crime in this way, we can revitalize the declining neighborhoods in our city."
下面是Amburg's Chamber of Commerce总裁的建议：
，那里破坏公物的行为一月之内减少了。，但破坏公物的发生率并没有变化。由于高强度照明灯显然是震慑犯罪的最有效途径，我们建议把用于自行车巡逻的费用用于在全市安装这种照明灯。通过这种方法减少犯罪率，我们将搞活市里正在衰落的街区。
Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.
173. The following appeared in a letter to the editor of the Balmer Island Gazette.
"The population on Balmer Island doubles during the summer months. During the summer, then, the town council of Balmer Island should decrease the maximum number of moped rentals allowed at each of the island's six moped and bicycle rental companies from 50 per day to 30 per day. This will significantly reduce the number of summertime accidents involving mopeds and pedestrians. The neighboring island of Torseau actually saw a 50 percent reduction in moped accidents last year when Torseau's town council enforced similar limits on moped rentals. To help reduce moped accidents, therefore, we should also enforce these limitations during the summer months."
下面这段文字出自写给Balmer Island Gazette杂志社编辑的一封信。
Balmer Island的人口在夏季翻了一番。为减少由机动脚踏车和行人引发的事故，Balmer Island市委打算本岛六个机动脚踏车出租公司的机动脚踏车的出租数量在夏季从每天50辆限制到每天30辆。这将大大减少夏天由机动脚踏车和行人引起交通事故。去年，邻岛Torseau市对机动脚踏车出租量采取了类似的限制，脚踏车事故较少了50%。为了减少机动脚踏车事故，我们应该在夏季采取这些限制。
Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted.
174. A recent sales study indicates that consumption of seafood dishes in Bay City restaurants has increased by 30 percent during the past five years. Yet there are no currently operating city restaurants whose specialty is seafood. Moreover, the majority of families in Bay City are two-income families, and a nationwide study has shown that such families eat significantly fewer home-cooked meals than they did a decade ago but at the same time express more concern about healthful eating. Therefore, the new Captain Seafood restaurant that specializes in seafood should be quite popular and profitable.
最近的销量调查显示Bay City餐馆的海鲜菜肴的消费量比过去五年增加了30%。而现在该市还没有专门经营海鲜菜的餐厅。而且，Bay City的大多数家庭是双收入家庭，一次全国性的调查显示这类家庭在家做饭的数量比十年前显著减少，同时他们更关注健康饮食。因此，在Bay City开设一家新的专营海鲜食品的餐馆将会非常受欢迎而且非常盈利。
