标题: 一道逻辑题，谢谢！ [打印本页] 作者: 春天的花儿会开 时间: 2003-11-6 11:43 标题: 一道逻辑题，谢谢！ 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. C. This year, the new companies starting up will not provide substantially more jobs per company than did new companies last year. the key: C 不知道这两个选项该如何区分？其他的选项都错的非常明显，谢谢 作者: cranberry 时间: 2003-11-6 22:43
仔细读一下，你可以发现明显的差别，文中所提供的信息是新的工作来源于老公司提供和新设立的公司，当老公司提供的工作数量少了，实际上应该依靠新公司提供足够多的工作，但题目的结论没有落在工作上而是落在公司的数目上，这样就要在公司数目和工作数量上建立一个联系，而C就是说的这个。A说的就不是文章所需要的了。
