The violent crime rate (number of violent crimes per 1,000 residents) in Meadowbrook is 60 percent higher now than it was four years ago. The corresponding increase for Parkdale is only 10 percent. These figures support the conclusion that residents of Meadowbrook are more likely to become victims of violent crime than are residents of Parkdale. The argument above is flawed because it fails to take into account A. Changes in the population density of both Meadowbrook and Parkdale over the past four years. B. How the rate of population growth in Meadowbrook over the past four years compares to the corresponding rate for Parkdale C. The ratio of violent to nonviolent crimes committed during the past four years in Meadowbrook and Parkdale D. The violent crime rates in Meadowbrook and Parkdale four years ago E. How Meadowbrooks’ expenditures for crime prevention over the past four years compare to Parkdale’s expenditures.
答案选D。但是我选的是B，因为犯罪率不是还要考虑人口吗？为什么不考虑这个方面？
