Roland: The alarming fact is that 90 percent of the people in this country now report that they know someone who is unemployed.
Sharon: But a normal, moderate level of unemployment is 5 percent, with 1 out of 20 workers unemployed. So at any given time if a person knows approximately 50 workers, one or more will very likely be unemployed.
Sharon's argument is structured to lead to which of the following as a conclusion?
The fact that 90 percent of the people know someone who is unemployed is not an indication that unemployment is abnormally high.
The current level of unemployment is not moderate.
If at least 5 percent of workers are unemployed, the result of questioning a representative group of people cannot be the percentage Roland cites.
It is unlikely that the people whose statements Roland cites are giving accurate reports.
If an unemployment figure is given as a certain percent, the actual percentage of those without jobs is even higher.
情景:Roland:令人吃惊的事实是本国90%的人说他们认识某个失业的人。
Sharon:但是正常来说,失业率是5%,20人有1个失业。所以在某时某人只要认识50个工人,那么1个或更多是失业的是非常可能的。
推理:本题问的是,从Sharon的说法中,可以得到什么结论。因此,本题属于演绎推理。
选题方式:不添加任何外部的信息,能推导出的选项即为答案。
选项分析:
A选项: Correct. 90%的人认识失业的人这个事实并不能表明失业率特别高。显然地,Sharon的意思就是这个,他解释了为什么会有这种90%的人都说自己认识的人里有失业的这个现象,并且阐述这种现象是十分正常的。
B选项:目前失业率不是适中的。题干中没有提到过现在的失业率到底是什么状态。
C选项:如果至少5%人失业,结果不可能是Roland所引用的比例。Sharon一直在阐述的是这样的比例是十分正常的,没有反驳Roland的数据。
D选项:Roland引用的人报告不可能是精确的。从题目中无法得知本选项的信息。
E选项:如果失业数字是一个比例,实际失业率会更高。 从题目中无法得知本选项的信息。
演绎推理:(得出结论C,不要出现新信息)
R:90%人认识失业者
S:But a normal, moderate level of unemployment 正常情况,适中的失业率为5%,20人里一人失业。这样如果一个人认识50人,1人或以上失业的概率很大
A选项(√)
The fact that 【90 percent of the people know someone who is unemployed,R的看法】 is 【not】 an indication that 【unemployment is abnormally high,S说这是正常的】.
90%的人认识失业的人这个事实【并不能表明not an indication that】失业率特别高。
