A、To inform him of a problem they face. B、To request him to purchase control desks. C、To discuss the content of a project report

W: Oh, hello, John. Are you using your dictating machine this morning? I’ve got a long report I must dictate. Could I borrow your machine?
M: Of course. But can you spare me a second?(19)It’s the message you sent to me about delivery delay of the control desks. What’s gone wrong?
W: Everything, John.(19)We have to get the steel sheets we need for these desks from new suppliers, while, the suppliers have got some trouble or other.(20)They say they will be a bit late for the delivery.
M: But they can’t be. These control desks are a special order. They are wanted for one of the big computer companies. It’s a very important contract.
W: When did it promise the delivery?
M: On Thursday next week. And there’s a penalty clause. We accept to lose 10 percent of our price for each week of overdue delivery.
W:(21)Oh, these penalty clauses. Why did you sales people accept them?
M:(21)We have to accept them; otherwise, we don’t get the contracts.
W: Well, let’s get on to the Buying Department. I already heard about the delay yesterday because we kept the production line clear to handle the special sheets. It’s a dreadful nuisance.
M: It will be more than a nuisance. If we don’t meet on the delivery date, it will cost us a lot of money.
W: Keep calm, John.(22)We can perhaps claim compensation from the steel suppliers for failure to deliver on time. Then we will settle the penalty clause.
M: Well, if we can.
