一道老题，我想知道我和出题人谁更傻？！

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.


划线部分指的是前年就有公司？有这么说话的么？我是这样以为的，This year, previously established companies=（去年的老公司+去年新开的公司），但是出题人指的是（去年的老公司，不包括去年的新公司），难道我错了？这题出的真没有歧义么？希望大家给我评评理

同学，你说的这个概念....很雷人....你想多了。去年建立的公司在今年来说肯定归为是established一类了。

比较的是在去年来说是老公司+去年建立的新公司 产生的job数与
今年来说的老公司+今年建立公司的新公司 产生的job对比。

就像上大学，某一年大一的是新生，大二以上的是老生。下一年，大一变大二，也就沦为老生一列了，而这一年进来的大一新生才是新鲜的血液啊...

那就不对了啊，题目说“去年来说是老公司+去年建立的新公司”今年增加的jobs不会比去年多，那只有再开新公司才能才能创纪录啊
那我就更不明白为什么选C了，除非C是“新开的公司不会压根就根本不招人”

unless a record number of companies start up this year这句话什么意思？它的意思如果“是除非今年新开与去年同等数量的新公司”我就懂了，如果是“今年新开一些新公司”那就不懂了，最根本的就在“a record number of ”上，GMAT啊，太难了！
