问题 Genera Technologies has developed a method that determines whether water is clean.
Each of the tests costs $ 42,500.

选项 A、Right
B、Wrong
C、Not mentioned

答案A

解析 借助题干中的特征结构$42,500作为答案线索,这样发现答案相关句:Genera has already sold ll of its tests at $42,500 a time in the UK and has a further four on order.该句说“Genera已经在英国以$42,500的价格出售了11件测试产品”,这与问题句的内容一致。
