Day 104
1. 鱼和水污染
一个州长提名 A 竞选 州长, 而之前有前任州长提名的人选在大选中 赢了。所以得出结论这次这个获得州长提名的人赢的可能性也很大。Flaw
之前赢得不代表之后赢,候选人情况不一样呢
2. 农民种柑橘
农民在果园里种柑橘,柑橘晚上的时候经常掉,导致产量减少,一 个政府就想要开发果园周围的 wetland 来种柑橘,但是农民纷纷反对,问原因。
农民反对政府开发wetland,开发wetland有什么副作用?比如影响柑橘产量啥的?
3. 犯罪率
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.
M地犯罪率比之四年前高60%
P地犯罪率比之前高10%
=>M更危险
错误在哪?之前的基数不知道,选D |
