: Which of the following, if known, would be most relevant to evaluating the

: 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。
