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 ~
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.
