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?

GWD 22 13一道真正的逻辑题!!!

Q13:

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.

答案选C,什么逻辑呀?请高手指点指点~~~完全想不通~~谢谢

文章说去年成立和之前已经成立的公司不会提供很多的工作机会,所以只有增加今年成立公司的数量来提供工作机会

但是没有考虑,如果今年公司成立的数量不多,但是每个今年的新公司提供的工作数量多的话,也就没有必要今年成立很多的新公司

C是对第二段的取非排除。

请问一下怎么理解这句话“This year, previously established companies will not be adding as many new jobs overall as such companies added last year. 

去年新成立的公司今年是否就转化为 previously established 了?

number of new jobs 来自两方面的贡献,A部分来自previously established companies ,B部分来自new companies starting up 。原文中对两年中A、B总和以及A部分分别做了比较,为了使A+B的比较成立,需要补充A部分的比较信息,即为C答案内容。

原文最后一句话虽然提及number of companies start up this year,但是我们关心的是这些公司带来的new job的数量,而不是这些公司的数量。
