Answer the questions that come after each, based solely on the information in the passage.    

Following a recent series of arson fires in public-housing buildings, the mayor of a large U.S. city has decided to expand the city's Community Patrol, made up of 18- to 21-year-olds, to about 400 people. The Community Patrol is an important part of the city's efforts to at least reduce the number of these crimes.    
In addition to the expanded patrol, the city also plans to reduce the seriousness of these fires, which are most often started in stairwells, by stripping the paint from the stairwell walls. Fed by the thick layers of oil-based paint, these arson fires race up the stairwells at an alarming speed.    
Although the city attempted to control the speed of these fires by covering walls with a flame retardant, it is now clear that the retardant failed to work in almost all cases. In the most recent fire, the flames raced up ten stories after the old paint under the newly applied fire retardant ignited. Because the retardant failed to stop the flames, the city decided to stop applying it and will now strip the stairwells down to the bare walls.
