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 我怎麼覺得每一個選項看起來都一樣@@ A B是因為去年所以才錯嗎?? 我是選B Assumption的題目好難 只能用找NOT 取非去WEAKEN結論 我只會用這個方法 不知道還有其他小技巧嗎??感謝!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.137.16.200

覺得這題的關鍵在兩個previously establish指涉的群體

是不一樣的吧

所以他的意思是因為Pre>=Pre'且New>=New'
01/15 21:26, 3F

01/15 21:26, , 4F
所以Pre+New>Pre'+New'(新)

New=公司數X均雇用人數 New'=公司數'X均雇用人數'
01/15 21:28, 5F

01/15 21:33, , 6F
又因公司數>=公司數' 所以Assume均雇用人數>=均雇用人數'

幾乎assumption都是取非了...

assumption的答案90%以上在否定和比較選項中
