解析

本题考查短对话的理解能力，需要根据对话内容推断说话者的隐含意图。关键点在于抓住对话中的关键词（如“tiny engines”“price”）并结合逻辑推理，排除干扰选项。

对话分析

  1. 对话核心：对话中可能提到废水回收系统（wastewater recycling）的问题，但说话者实际担心的是微型发动机的价格（tiny engines' price）。
  2. 干扰项排除：
    • A选项（担心废水回收）是表面问题，但对话中可能通过“price”暗示真实担忧。
    • C、D选项与废水相关，但未在对话中提及。
  3. 逻辑推断：通过“price”一词锁定B选项，即说话者的真实意图是担心成本问题。
