GMAT-6-22请教求解思路



























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











changes in the population density of both Parkdale and Meadowbrook over the past four years





how the rate of population growth in Meadowbrook over the past four years compares to the corresponding rate for Parkdale





the ratio of violent to nonviolent crimes committed during the past four years in Meadowbrook and Parkdale





the violent crime rates in Meadowbrook and Parkdale four years ago





how Meadowbrook’s expenditures for crime prevention over the past four years compare to Parkdale’s expenditures

选D


只有知道4年前的各自暴力犯罪率,才能知道上升各自的百分比后,今年的犯罪率。


欢迎讨论
