单选题 What was the author's attitude towards the industry awards for quieter equipment?

【正确答案】 A
【答案解析】推理判断题。文章最后一段第三句指出“Many people optimistically thought industry awards for better equipment would stimulate the production“quieter appliances.”“Optimistically”意为乐观地,有些人乐观地以为靠颁发工业奖项就能够刺激厂家生产噪音较小的家用电器,“乐观”一词隐含工作者对于此种做法的态度应是怀疑的态度,所以正确答案应选择A。
