Re: [問題] 請問有關CR的assumption題
之前有大牛提供了一個方法
方法一
結論有新觀念 找有not的選項
結論沒有新觀念 去找新觀念
最近在寫assumption的題目 我發現這個方法多少有幫助
手足無措的時候可以用
方法二
在選項前加not 看可不可以反駁結論
方法三
最後是老方說得 assumption像是一個橋 他要連接前提和結論
如果兩方有一方不是橋的兩邊 必錯
我自己也在努力中啦<目前有進步> 這是我自己整理的小筆記
大家參考看看啦
※ 引述《aaaaaakoyasu (六點半天色還沒亮)》之銘言：
: ※ 引述《betterman720 (betterman)》之銘言：
: : 以PP2-CR-40舉例好了
: : 40. (32847-!-item-!-188;#058&007552)
: : A recent report determined that although only three percent of drivers on
: : Maryland highways equipped their vehicles with radar detectors, thirty-three
: : percent of all vehicles ticketed for exceeding the speed limit were equipped
: : with them. Clearly, drivers who equip their vehicles with radar detectors
: : are more likely to exceed the speed limit regularly than are drivers who
: : do not.
: : The conclusion drawn above depends on which of the following assumptions?
: : (A) Drivers who equip their vehicles with radar detectors are less likely to be
: : ticketed for exceeding the speed limit than are drivers who do not.
: : (B) Drivers who are ticketed for exceeding the speed limit are more likely to
: : exceed the speed limit regularly than are drivers who are not ticketed.
: : (C) The number of vehicles that were ticketed for exceeding the speed limit
: : was greater than the number of vehicles that were equipped with radar
: : detectors.
: : (D) Many of the vehicles that were ticketed for exceeding the speed limit
: : were ticketed more than once in the time period covered by the report.
: : (E) Drivers on Maryland highways exceeded the speed limit more often than
: : did drivers on other state highways not covered in the report.
: : 答案是(B)
: : 想很久還是不知道為什麼
: : 有牛人願意解惑嗎?
: : 小弟先謝過了^^
: 題目：
: 該州3%的人裝有雷達探測器
: 該州被開超速罰單的人33%裝有雷達探測器
: 作者結論：
: 裝有雷達探測器的人比沒裝的人較會超速
: 前提是：
: 被開超速罰單的人都是因為常超速才會被開單，
: 如果是偶爾才超速卻常被開單的話（＝被開單的都是很少超速的人），
: 整篇的立足點就消失了。
: 所以答案是B
