标题: GWD-8-Q13~~~请教，请教~~~

GWD-8-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?

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

B.The number of people seeking employment is no larger this year than it was 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.Previously established companies in Derderia will be less profitable this year than such companies were last year.

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

请问，highlight部分是什么意思？我的理解是：今年如果有一大批的新公司建立的话，就有可能超过前年的记录。
所以，我选了A.也就是说这个结论的前提是：新公司找的人比去年已经建立的公司招的人多~~~~

但是正确答案C,请问我是哪里理解错了？

highlight部分的意思是：除非今年又有破纪录的一大批新公司成立，否则新工作的记录不会被破。

新公司数*公司提供的职位数=总JOB数

今年如果新公司提供的职位数量少于去年，那么新公司数必需破纪录，才能令总JOB数破纪录。

所以C是正确的

A的答案正好相反，如果今年新公司提供的职位数多了，那么就不一定需要新公司的数量破纪录了。

A and C are inverse.
Input C into the argument.
Because the start up company will create no more jobs than previous year, so only a record number of companies are established, so that they can break its record of new jobs created.

If you chose A, then you can't get the conclusion.
