 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.

答案是C  不過我選了A

想請問一下為什麼A不行??

我覺得A也可以阿  還是我題目理解有問題~"~

我看的題目是說: 因為去年建立新公司,所以創造了新紀錄的工作數量

                        而今年那間去年創建的公司不打算add這麼多工作機會,

                        所以  如果要有新紀錄的話,就只能再創造一間新公司了

A說每年創建新公司帶來的工作機會都會多於前一年

這個假設不對嗎?  不就是因為這樣  所以作者才說只有創造新公司  才能打破紀錄

請NN指教  謝謝

工作是由新舊公司一同創造，文中說今年舊公司無法創造與去年舊公司一樣多的工作，因此除非新公司數目增加不然工作不會增加，所以完全不要管舊公司。

如果今年新公司要提供比去年新公司更多工作機會，有兩個情況：

1.新公司較多

2.平均而言，每個今年新公司提供工作機會都比去年新公司多

既然題目已經得到1的結論，表示2.必須要被排除，所以要選C

A錯在each year不對～無法從文中推出
