T-3-Q29.
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.
C.    Whether the process of cleaning the coal is more expensive than the process of filtering the emissions
D.    Whether lawful emissions of sulfur dioxide form coal-burning plants are damaging the environment.
E.    Whether existing plants that use the filtering equipment could replace this equipment with the cleaning equipment and still complete with new plants that install the cleaning equipment.

算是一道狗,楼主给的答案是B,但是新厂的安装费有可能远大于旧的,也可能只是大一点,所以和装置本身费用加起来没法确定有没有省钱呀.....
个人觉得是C,希望大家来看看~

选  C

minisheep

C吧

我也做過這題
但我看到的答案就是C啊
不是B
所以選C吧
B很明顯就是錯的 - 提到新舊工廠的比較已超出原文討論範圍了

我也做过这道题~~答案是C啊~~

答案是C啊 LZ是不是看错啦

花开声音620

是C,强调花费

melvinperson

应该选C

但我不得不说一句惭愧 其实一开始我也选的是B 是因为我没看清楚题目

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. 我当时想的是对比安装新的chemical cleaner (也是就是the new one) 的expense和旧的filter的花费的比较 但是我仔细看了看发现其实B选项比较的不是以上两个 我猜当时狗主人应该也犯了同样的错误吧
