1. 农村孩子耐过敏
有一道评价题。农场上的动物身上好像有个什么东西能导致过敏。农场小孩比城市小孩更能抵抗过敏因为他们经常接触这些动物。所以为了抵抗过敏,应该多接触这些物质。 以下哪个most helpful in evaluating the argument。
就是判断接触频率和过敏的关系
2. 犯罪率
The violent crimerate (number of violent crimes per 1,000 residents) in Meadowbrook is 60percent higher now than it was four years ago. The corresponding increase forParkdale is only 10 percent. These figures support the conclusion thatresidents of Meadowbrook are more likely to become victims of violent crimethan are residents of Parkdale.
The argument aboveis flawed because it fails to take into account:
A. changes in thepopulation density of both Parkdale and Meadowbrook over the past four years
B. how the rate ofpopulation growth in Meadowbrook over the past four years compares to thecorresponding rate for Parkdale
C. the ratio ofviolent to nonviolent crimes committed during the past four years inMeadowbrook and Parkdale
D. the violent crime rates in Meadowbrook and Parkdale fouryears ago
E. how Meadowbrook’sexpenditures for crime prevention over the past four years compare to Parkdale’s expenditures
D, 只说了增长率,没说之前啥样
3. 气候预测
关于climate预测,气象学家见了一个新的computer system/software 可以准确预测。用这个新的东西来输入pastdate都显示的很准,所以它推测未来20年气温会上升0.4度也是accurate的。
求weaken。 它是根据过去数据来判断的,所以肯定准,但是未来不一定啊。 目前天气变化比以往更大,更难以预测。 |
