(单选题)

Which of the following is true? ( )

A.You should separate new and mature customers in testing your products.

B.Approximate customers are equally valuable as real users.

C.Salespeople have a lot of customer contact, so they have the same motivations as customers.

D.Usability test aims to please the customers.

参考答案：A

参考解析：

从倒数第三段可得知，文章是在强调区分新老顾客测试产品的重要性，B接近的消费者和真正使用者不是一样的，因为接近的消费者可以装作，故排除，C和原文正好相反，尽管他们有很多顾客联系方式，但他们没有同样的动机。只有A符合原文。故本题正确答案选A。
