※ 引述《lovekyoko (今年在芝加哥跨年 )》之銘言： : If the airspace around centrally located airports were restricted to : commercial airliners and only those private planes equipped with radar, most : of the private-plane traffic would be forced to use outlying airfields．Such : a reduction in the amount of private-plane traffic would reduce the risk of : midair collision around the centrally located airports． : 35. Which of the following, if true, would most strengthen the conclusion : drawn in the second sentence? : (D)The number of midair collisions that occur near centrally located : airports has decreased in recent years． : (E) Private planes not equipped with radar systems cause a : disproportionately large number of midair collisions around centrally located : airports． : 這題答案是E 但是我第2次看我有可能會選D : 第2段的結論是說因為私人飛機數量減少所以會降低空中碰撞的風險 : D說空中碰撞的數量降低在最近幾年我覺得也有支持阿 : 為什麼D錯解答是說 A recent reduction of the number of collisions does not : explain their cause．我還是看不太懂 : 有人可以解釋一下嗎 ORZ 你注意他是問啥? 它不是在問你結論它是在問你哪個條件強化結論題目說機場只允許商用機與配有雷達的私人飛機飛越機場中央地帶的區域 (方法) 結果將會降低飛機在那區域相撞的風險 (結論) 下面的選項要找的不是結論結論題目給你了他要你找的是條件也就是說以下哪個條件會使得這個結論更加有力 E這答案就很符合因為你限制沒雷達私人飛機必須就是因為這些飛機常引起災難否則你限制它就沒用啦至於D 他可以作為這個措施實施後的最後結論如果你把它當作條件題目給的結論(降低相撞風險)反而因此被削弱了總言之題目是在問你哪個條件(situation)之下會使題目所提到的結論(conclusion) 更加成立 -- No doubt, just keep walking -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.168.74.96
