Re: [問題] 請問有關CR的assumption題
※ 引述《betterman720 (betterman)》之銘言：
: 從七月多開始準備AT到現在
: 最近剛做完OG OV OQ以及PP1 PP2
: 可是一直以來對assumption題一直存在疑惑
: 每次遇到這種題目總是有點憑感覺的猜 覺得很不踏實
: 之前補習的時候老師說過"assumption就是選題目中証據跟結論的主題"
: 覺得還滿難意會的@@
: 不知道有沒有牛人願意分享這類題該怎麼解?
: 以PP2-CR-40舉例好了
我是這樣做的,
assumption題是指題目做結論的"前題"
意即..如果選項前加否定字或把否定字眼去掉 則題目的結論必不成立
: 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.
題目給的:
前提
3%的人(該州全部的人) 裝雷達偵測器
33%的人(被開超速罰單的人) 有裝了偵測器
結論
裝偵測器的人比較愛超速
自己想的:
前提證明裝了雷達偵測器的人比較容易被開罰單
因為裝偵測器的人只暫了總人口的3% 卻占了罰單數量的33%
但題目給的結論為愛超速
容易被開罰單並不完全等於愛超速
: The conclusion drawn above depends on which of the following assumptions?
: (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.
選項若加個否定,
如果 容易被開罰單不等於愛超速的話,則題目結論有誤
故選B
