※ 引述《Birou (十里春風不如你)》之銘言： : Newspaper editorial: : In an attempt to reduce the crime rate, the governor is getting tough on : criminals and making prison conditions harsher. Part of this effort has been : to deny inmates the access they formerly had to college-level courses. : However, this action is clearly counter to the governor's ultimate goal, : since after being released from prison, inmates who had taken such courses : committed far fewer crimes overall than other inmates. : Which of the following is an assumption on which the argument depends? : A. Not being able to take college-level courses while in prison is unlikely : to deter anyone from a crime that he or she might otherwise have committed. : B. Former inmates are no more likely to commit crimes than are members of the : general population. : C. The group of inmates who chose to take college-level courses were not : already less likely than other inmates to commit crimes after being released. : D. Taking high school level courses in prison has less effect on an inmate's : subsequent behavior than taking college-level courses does. : E. The governor's ultimate goal actually is to gain popularity by convincing : people that something effective is being done about crime. : 答案 (C) : 這題是認定大學課程可以減少囚犯再犯率，那為何答案 (A) 不行呢? : 請眾高手幫忙解答，謝謝 Assumption 的題目，主要是抓題目有提到的因果關係和因果關係無關的，基本上不會為正確答案此題的因果關係為: 上過大學課程的囚犯犯罪率低 --> 大學課程可減低再犯率而正確答案 (C) 指出上大學課程的囚犯在上課前，並不是本來就比較不會犯罪的一群 (犯罪率低) 可以瞭解這個上課族群的樣本是客觀的，才能證明上課的確能降低犯罪率答案 (A): 不拿大學課程就不可能赫止犯罪率其實這條件不是完全在比較大學課程和犯罪率的關係，而是也間接的提到其他方法沒有用而 assumption 的題型，要 focus 在原題討論的範圍: 大學課程 VS 犯罪率降低的關係其他方法是否有效，跟此題並沒有關係，所以 (A) 當然沒有 (C) 來的有關正確答案 (C) 沒問題 -- Donz GMAT 6-7 月實力班: http://www.donzgmat.com/course-5weeks Donz GMAT FB: https://www.facebook.com/groups/DonzGMAT Donz 全科線上機經課: http://ndxica.pixnet.net/blog/post/41525434 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 101.9.177.41 ※ 文章網址: https://www.ptt.cc/bbs/GMAT/M.1493222250.A.6D2.html ※ 編輯: ndxica (101.9.177.41), 04/26/2017 23:58:48
