标题: 一道逻辑题 想不通 求解答 [打印本页] 作者: 3277135 时间: 2018-6-26 20:03 标题: 一道逻辑题 想不通 求解答 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.
我的思路是:去年,随着一大批新公司开立和之前开的公司增加了很多job ---去年很多的new job was created
今年,之前开立的公司不会向去年一样增加一样多的job。
结论: 除非今年开立一大批公司,否则D地区不会打破new job created的记录
assumption是今年新开立的公司创造的job比去年多才会打破记录吧
为什么不选A
c为什么对?
求大神解答
E,无关选项。本逻辑的重点在于创造的工作数量,而不是总共的工作数量。Gross vs Net。作者: 3277135 时间: 2018-6-26 21:53
是不是这个意思
如果对c取非,那就是 This year, the new companies starting up will provide substantially more jobs per company than did new companies last year.
即 今年今年新开立的公司,每个公司会比去年的新公司提供更多相当多的工作。
那么既然每个公司可以提供相当大的工作,就不需要结论的a record number of companies相当多的公司,取反削弱了结论。故选C作者: cycgundam 时间: 2018-6-26 22:38
我并不清楚取非什么意思,因为我逻辑没用中文材料或课复习。但从你的解释来看确实如此。这也是这种题的难度所在。
