Bat大神,我看了你的帖子觉得非常有帮助,不过我对于辨识【因果型】和【非因果型】仍然有困难。看到你在page2里说过【因果型】是解释了前提的感觉。但仍然有些疑惑。
以下这题,我感觉它是【非因果型】的,你觉得呢?
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 Parkdale and Meadowbrook over the past four years 分析A选项
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 Meadowbrook's expenditures for crime prevention over the past four years compare to Parkdale's expenditures
盼望解答^^谢谢 |
