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?

    

 

    

(A)
Each year, new companies starting up create more new jobs overall than do
previously established companies.

    

(B)
Companies established last year will not add a greater number of jobs overall
this year than they did last year.

    

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

    

(D)
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.

    

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

文中such是否仅指代第一句中的previously established companies,而不包括去年新成立的companies。如果也指代去年建立的，那去年建立的companies可以提供更多的jobs，而不需要由今年建立的companies提供。
