※ 引述《life2002 (dog days)》之銘言： : Q31: : Although most smoking-related illnesses are caused by inhaling : the tar in tobacco smoke, it is addiction to nicotine that : prevents most smokers from quitting. In an effort to decrease : the incidence of smoking-related illnesses, lawmakers in Sandonia : plan to reduce the average quantity of nicotine per cigarette by : half over the next five years. Unfortunately, smokers who are : already addicted to nicotine tend to react to such reductions : by smoking correspondingly more cigarettes. : The information above most strongly supports which of the following : predictions about the effects of implementing the Sandonian : government’s plan? : A) The average quantity of tar inhaled by Sandonian smokers who : are currently addicted to nicotine will probably not decrease : during the next five years. : B) Sandonian smokers who are not already addicted to nicotine : will probably also begin to smoke more cigarettes during the : next five years than they had previously. : Answer:A : 可以請教一下各位 這題的答案為何是A而非B? : 我搞不清楚為何"平均攝入tar的量並不會減少"會是此題的supporting point? : thanks. 簡單的說 政府打算把菸裡頭的尼古丁含量減少 以降低焦油對人體的為害 並且題目最後明白表示 那些已有煙癮的人 會抽更多的菸來彌補每根菸尼古丁的減少量 所以這樣的訊息提供了一個預測 就是那些成癮者吸入焦油的量 不會因為這樣的措施 而減少 A選項是針對題目中最後一句:"intend to react to such reductions by smoking correspondingly more cigarettes"而來---->也就是政府給我少多少 我就給你吸回多少 的意思 此外 題目並未提供任何訊息是關於未成癮者的 換句話說 未成癮者會怎樣並不在此題目 的探討範圍內 並且B是說 那些沒有成癮的人 也會開始抽更多的菸 顯然在題目中並沒有 隱射到這部份 -- No doubt, just keep walking --
