The air quality board recently informed Coffee Roast, a small coffee roasting firm, of a complaint regarding the smoke from its roaster. Recently enacted air quality regulations require machines roasting more than 10 pounds of coffee to be equipped with expensive smoke-dissipating afterburners. The firm, however, roasts only 8 pounds of coffee at a time. Nevertheless, the company has decided to purchase and install an afterburner.

Which of the following, if true, most strongly supports the firm's decision?


Until settling on the new air quality regulations, the board had debated whether to require afterburners for machines roasting more than 5 pounds of coffee at a time.

Coffee roasted in a machine equipped with an afterburner has its flavor subtly altered.

The cost to the firm of an afterburner is less than the cost of replacing its roaster with a smaller one.

Fewer complaints are reported in areas that maintain strict rules regarding afterburners.

The firm has reason to fear that negative publicity regarding the complaints could result in lost sales.

考题讲解

情景：Coffee Roast被告知要减排。现在的法律是，如果烘焙10榜的咖啡，就必须要安装一个烟雾消散器。但是呢，这个公司一次只烘焙8榜，他还是准备安装一个消散器。

推理：本题是一个“现象解释型考题”。按照正常逻辑来说，即，结论为“offee Roast这个公司不必要安装消散器”。顺序的因果逻辑：因为Coffee Roast这个公司一次只烘焙8榜，所以它不必要安装消散器
（因）前提：Coffee Roast这个公司一次只烘焙8榜
（果）结论：它不必要安装消散器

选题方式：因果推理只有一个评估方向，简而言之，即（由于本题问的是加强，所以答案选项需在“取非”后满足），反驳推理文段中的结论。

选项分析：

A选项：直到新的空气规定落实之前，公司董事会一直在讨论是否要求机器每次烘焙出5榜以上的咖啡。首先，公司董事会讨论并不代表决议。其次，5榜以上也不代表一定会超过10榜。

B选项：在按照了消散器的机器里烘焙出的咖啡的味道会有细微的改变。味道改变与否和推理文段所讨论的结论无关。

C选项：安装消散器的成本小于换一个烘焙器的成本。现在Coffee Roast公司本身也不超过规定安装消散器的烘焙咖啡量，所以，无论两者成本如何，均和本题的结论无关。

D选项：在有严格环境要求的地方有更少的抱怨。更少的抱怨和公司的利益并不直接相关，自然也不是安装消散器的原因，所以本选项和推理文段的结论无关。

E选项：Correct. 公司有理由去担心负面的关于有烟的抱怨会影响公司产品的销量。如果有烟的抱怨会影响销量的话，那么公司经过权衡就可能会在法律认为不必要的情况下安装烟雾消散器。
