GWD原题犯罪率问题 版本一:foxwill (6/15.750) GWD的原题:近四年城市犯罪率增长了百分之60,b增长了百分之10,所以前者居民更容易犯罪了。问它错在没指出什么。我选的是:四年两者的犯罪率。(不过好像GWD的答案不是这个呃。。。我当时还是坚信这个最好,请nn们求证一下)。 原题: T-4-Q20 天山-7-22 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 Meadowbrook and Parkdale 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 Meadowbrooks’ expenditures for crime prevention over the past four years compare to Parkdale’s expenditures.
版本二:foolfrog (6/26, V35,710, 6/27更新) 近四年来M城市犯罪率增长了64%,L城市增长了40%,这说明M城市的市民更容易犯罪。问错在没有指出什么:我选择的是“四年前M城市和L城市各自的犯罪率”(好像和GWD原题答案不一样,请大家自己考虑吧) |
