※ 引述《s81712 (s81712)》之銘言： : 因為想不太通B與C(兩個TOPIC比較相關的)， : 感覺ANS是C但是又不知道為什麼那邊會出現"碳"， : 還是我就別想太多了? : ~"~謝謝大家的指教 : The emission of sulfur dioxide when high-sulfur coal is burned is restricted : by law. New coal-burning plants usually comply with the law by installing : expensive equipment to filter sulfur dioxide from their emissions. These new : plants could save money by installing instead less expensive cleaning : equipment that chemically removes most sulfur from coal before combustion. : Which of the following, if known, would be most relevant to evaluating the : claim above about how new coal-burning plants could save money? : A. Whether existing oil-burning plants are required to filter sulfur dioxide : from their emissions : B. Whether the expense of installing the cleaning equipment in a new plant is : less than the expense of installing the cleaning equipment in an older plant : ^^^^^^^^^^^ ^^^^^^^^^^^^^^ : 是否引起無關比較? : C. Whether the process of cleaning the coal is more expensive than the : ^^^^^^^^^^^^^^^^^^^^^為什麼會是清理碳?! : process of filtering the emissions 採行方法達成目的的結論句，這種結論句正確答案常出現"原來沒有考量到的因素"，所以請注意答案可能出現題幹沒出現過的資訊，這裡的推理關係如下: installing less expensive cleaning equipment --- could save money 雖然equipment比較便宜，但是需要清理equipment的coal會更耗成本，就達不到save money這個目的。答案B是無關比較，因為整個主角在討論these new plants要裝哪種equipment，和舊的無關。 -- A兔GMAT作戰中心 http://tw.myblog.yahoo.com/tootoo5478/ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.25.229.219
