先前，有位戰友問了我一題「卡關」的CR題。
在跟他一同討論之後，我想這個題目是可以很好地解釋考試時「技巧」使用的時機，
以及技巧之前，自己應該培養的邏輯直覺。所以在此分享。
（先說明一下，我比較注重的是講解我在實戰中真的遇到這一題的心態，
包括如果發現讀不下去/抓不到點時該怎麼調整。
真的看不懂的字，我也會很老實地說看不懂。
因為若是開始翻譯題目，那有些時候會流於馬後砲式的詳解，對實戰的幫助有限。
當然，平時練習對於題目邏輯的扎實訓練跟完整理解也很重要，
不過本篇的重點我會放在「實戰卡關如何突破」之上。
所以本題的講解會寫得有點長，請見諒）
請各位先來做做這一題：
A significant number of complex repair jobs carried out by Ace Repairs have
to be reworked under the company’s warranty.The reworked jobs are invariably
satisfactory.When initial repairs are inadequate, therefore, it is not
because the mechanics lack competence; rather, there is clearly a level of
focused concentration that complex repairs require that is elicited more
reliably by rework jobs than by first-time jobs.
The argument above assumes which of the following?
A.There is no systematic difference in membership between the group of
mechanics who do first-time jobs and the group of those who do rework jobs.
B.There is no company that successfully competes with Ace Repairs for complex
repair jobs.
C.Ace Repairs’ warranty is good on first-time jobs but does not cover
rework jobs.
D.Ace Repairs does not in any way penalize mechanics who have worked on
complex repair jobs that later had to be reworked.
E.There is no category of repair jobs in which Ace Repairs invariably
carries out first-time jobs satisfactorily.
