※ 引述《fshy (GMATing)》之銘言： : 目前假設題的作法我都是有not取掉not, 或沒not補上not來當反駁題作. : 可是今天做PP2時做到此題. 此題看別人的解法算是"搭橋". : 但我ㄧ開始當反駁題做確非常的繞(即取非) ~ 花了很多時間 : 所以請問ㄧ下各位神人, 當您們看到假設題時. 您們的作法是 : (1) 全部先取非當反駁題做. 有些雖然繞但還是解的出來 : (2) 全部先取非, 等無法順利解時在從正面思考下手 : (3) 讀完題目都就知道是用搭橋方式解或是當反駁 : 我現在是無法用(3)方法, 頭腦沒這麼靈活在短時間判斷出來. : 現在全部的假設題都當反駁先做.可今天此題就踢了鐵板 ~ : 還是這題當反駁也是可以很快? : 謝謝 ~ 我之前看CD有人是這麼解的: b：那些被開單的司機平時就更容易超速。如果b取非就成了：被開單的司機平時不那麼容易超速。所以那些被開單的有radar的司機可能本身很多時候都沒有超速，只是這些司機運氣不好，好不容易超速就被逮了，那就削弱了結論。 : 註: "搭橋"就"類似" 題目A-B, B-C, 然後答案找連結. : 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. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.4.234
