160) The following appeared in a recommendation from the President of the Amburg Chamber of Commerce.
Last October, the city of Belleville installed high-intensity lighting in its central business district, and vandalism there declined almost immediately. The city of Amburg, on the other hand, recently instituted police patrols on bicycles in its business district. However, the rate of vandalism here remains constant. Since high-intensity lighting is clearly the most effective way to combat crime, we recommend using the money that is currently being spent on bicycle patrols to install such lighting throughout Amburg. If we install this high-intensity lighting, we will significantly reduce crime rates in Amburg.
Write a response in which you discuss what questions would need to be answered in order to decide whether the recommendation is likely to have the predicted result. Be sure to explain how the answers to these questions would help to evaluate the recommendation.
172) 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.
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.

G2: The city of Amburg, on the other hand, recently instituted police patrols on bicycles in its business district.However, the rate of vandalism here remains constant.
C1: Since high-intensity lighting is clearly the most effective way to combat crime,
C2: we recommend using the money that is currently being spent on bicycle patrols to install such lighting throughout Amburg.
C3: If we install this high-intensity lighting, we will significantly reduce crime rates in Amburg.
A1 (G1, C1): Installing lighting can curb vandalism in the long term.
A2 (G1, C1): Installing lighting can deal with other crimes.
A3 (G2, C1): Vandalism was a major concern in Amburg and police patrols could not address this.
A4 (G2, C1): Bicycle patrols were not helpful for dealing with other crimes.
why vandalism declined immediately and whether or not it will rebound
- maybe the criminals were not used to the lighting and stopped vandalizing temporarily
- once they get used to the change they might start vandalizing again (need to track the long-term effects
whether the vandalism rate was high in Amburg and the issue needs to be tackled
- perhaps vandalism rate was really low and there is little room for improvement
- and the reason why police patrol had little effects might be that the issue was not serious
how effective are lighting and police patrols for treating the other crimes in Amburg
- perhaps the crime rates could be more significantly reduced by focusing on other crimes such as theft and robbery
- maybe police patrols are more effective for such crimes
