Q20

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

1. Changes in the population density of both Meadowbrook and Parkdale over the past four years.

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

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

4. The violent crime rates in Meadowbrook and Parkdale four years ago

5. How Meadowbrooks’ expenditures for crime prevention over the past four years compare to Parkdale’s expenditures.

为虾米答案选D不选B内？怎么想也想不通。。。。

Q38

In one state, all cities and most towns have antismoking ordinances, a petition entitled “Petition for Statewide Smoking Restriction” is being circulated to voters by campaign workers who ask only, “Do you want to sign a petition for statewide smoking restriction?” The petition advocates a state law banning smoking in most retail establishments and in government offices that are open to the public.

Which of the following circumstances would make the petition as circulated misleading to voters who understand the proposal as extending the local ordinances statewide?

1. Health costs associated with smoking cause health insurance premiums to rise for everyone and so affect nonsmokers.

2. In rural areas of the state, there are relatively few retail establishments and government offices that are open to the public.

3. The state law would supersede the local antismoking ordinances, which contain stronger bans than the state law does.

4. There is considerable sentiment among voters in most areas of the state for restriction of smoking.

5. The state law would not affect existing local ordinances banning smoking in places where the fire authorities have determined that smoking would constitute a fire hazard.

这个，不知道选什么哦。。我觉得选C，答案好像给的B，那个晕哦……

犯罪率是个相对概念，包括了人口变动的因素．而此题中，比较的基础是四年前两个城市的犯罪率，如果基数不同，那么如此比较产生的结论也不同．
