听力原文：W: Sound and Vision, Administrative Department, Eve Wheeler speaking. Can I help you? M: Good afternoon, madam. This is John Cruise. I wish to register a complaint about my video recorder. W: I see. I hope I can be of some help. Can you explain what the problem is, please? M: Well, the recorder has severely damaged two quite valuable tapes of mine. And you guaranteed that this machine is the best there is. I hope you understand that a simple repair is just not enough I demand compensation for the lost tapes as well. W: I'm sorry that's all very unfortunate. I'm sure something can be done. I will put you through to our legal consult-ant, Mrs. Schroder. One moment, please. (dialing sound... ) Hello, Mr. Cruise? Thank you for waiting. I'm aw-fully sorry, but Mrs. Schroder is having a meeting right now. Could she call you back later this afternoon? M: I hope you're not trying to get rid of me. W: Not at all, sir. I have noted your complaint and I will urge Mrs. Schroder to call you back as soon as possible. Could I have your phone number, please? M: Yes. It's 0181 945 8719. W: Thank you very much. Goodbye. M: Bye. What's the possible relationship between the two speakers?
