With a record number of new companies starting up in Derderia, and with previously established companies adding many new jobs, a record number of new jobs were created last year in the Derderian economy. This year, previously established companies will not be adding as many new jobs overall as such companies added last year. Therefore, unless a record number of companies start up this year, Derderia will not break its record for new jobs created.

Which of the following is an assumption on which the argument relies?

With a record number of new companies starting up in Derderia, and with previously established companies adding many new jobs, a record number of new jobs were created last year in the Derderian economy.  This year, previously established companies will not be adding as many new jobs overall as such companies added last year.  Therefore, unless a record number of companies start up this year, Derderia will not break its record for new jobs created.

 

Which of the following is an assumption on which the argument relies?

 

  1. In a given year, new companies starting up create more new jobs on average than do previously established companies.

  2. The number of people seeking employment is no larger this year than it was last year.

  3. This year, the new companies starting up will not provide substantially more jobs per company than did new companies last year.

  4. Previously established companies in Derderia will be less profitable this year than such companies were last year.

  5. The number of jobs created in the Derderian economy last year was substantially larger than the number of jobs lost.

答案是C,牛牛给分析分析吧,看得有点乱

(1)去年的职位总数=新建立企业的职位数+老企业的职位数

(2)今年的职位总数(增加)=新建立企业的职位数(增加)+老企业的职位数(减少)

(3)新建立企业的职位数(增加)=平均每个企业的职位数(?)*新建企业数(增加)

(2)-(1)》0根据题意就要满足括号备注的情况,其中?是题中未说的,既是所求

?是增加才能满足题意,就是c项

两分钟时间内做这么详细的分析还真是不容易(又要读题,搞清楚问的什么,还要分析清楚,再结合各选项选择)。

最好还是用有关无关来迅速判断,抓住Argument的前提和结论(是关于新增工作的),能够把BDE去掉。剩下的A和C当中,就比较好选了。
