M: Good morning. What can I do for you?
W: Good morning. Could I talk to Jeffry Harding please?
M: Speaking.
W: Hello, Jeff. It’s Helen.(8)I got your message on the answering machine. What’s the problem?
M: Oh, Helen. Well, it’s the Grimsby plant again, I’m afraid.(9)The robots on Line 3 have gone wrong. And the line is at a standstill.
W: Can’t you replace them with the stand-ins?
M: I’m afraid not. The stand-ins are already in use on Line 6. And the ones from Line 6 are being serviced.
W: When did this happen, Jeff?
M: Well, they’ve been making a low continuous sound for a day or two. But they finally went dead at 2:30 this afternoon.
W: I see.(10-1)What did you do? Have you tried the whole plant?
M:(10-2)Not yet, Helen. I thought I’d better get your OK first.
W: OK. Get on the phone to Tom, and try to get their stand-ins over tonight. We have to be back at full capacity tomorrow morning. Is it a major job to repair our robots?
M: About a week. That’s what the maintenance engineer says.
W: Right. Well, if you can get the ones from Tom, please ask Tom to inform Sheffield that he may need their stand-ins in case of emergency during the next week.
M: OK. Thank you very much, Helen.
W: You are most welcome.
M:(11)Sorry to spoil your day off.
W: It doesn’t matter.
