With a record number of new companies starting up in Derderia and with previously established companies adding many 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?
Each year, new companies starting up create more new jobs overall than do previously established companies.
Companies established last year will not add a greater number of jobs overall this year than they did last year.
This year, the new companies starting up will not provide substantially more jobs per company than did new companies last year.
This year, the overall number of jobs created by previously established companies will be less than the overall number of jobs lost at those companies.
The number of jobs created in the Derderian economy last year was substantially larger than the number of jobs lost last year.
增加的工作 = 新公司提供的工作(平均每个公司提供的工作*公司数)+ 老公司提供的工作
今年老公司提供的工作 < 去年老公司提供的工作
结论：除非,今年新公司数目 >去年新公司数目， 今年增加的工作才会比去年增加的多
求假设
C 其假设是 平均每个公司提供的工作 没有增加
取非。我们假设每个公司提供的工作增加了，那么不用增加公司数目，就可以提供很多工作了，削弱结论
A 每年， 新公司提供的工作 比 老公司提供的工作 更多。 这个是无关项。
