input: Please answer the following: W: Good morning. I'm thinking of sending a parcel to New York next week. Can you tell me what the procedure is, please? M: Certainly. When you ring us, we need the following information. The invoice address: that's probably your address, isn't it? And then, the pickup address. That's different. And the contact phone number. W: Just a moment. I'm taking notes. Phone number, right. M: Then we need the full name, address and phone number of the person you are sending the parcel to. W: Ok, anything else? M: Yes, the weight and dimensions of the parcel. That's height, weight and length. And the value of the goods and full description. W: Value, description. M: Yes, but don't seal the parcel. You need to leave it open so that the driver can check the contents when he collects it. After the recent bombing, the airline said that we'd have to check all parcels. They told us we had to do it. W: Fine. Now last question. How long will the parcel take to get to New York? M: One to two working days. There are daily flights at midday. And if we collect the parcel from you at 10:15 then your parcel catches that flight and it will arrive in 24 hours. W: Right. Thank you very much. You've been very helpful. M: Not at all. Goodbye. W: Goodbye. What was said before this conversation?

output: M: Parcel Express, good morning! How can I help you?
Please answer this: W: I can't wait to see Canada, Jason, but I'm scared stiff of the journey. My husband insists on flying, but I want to sail. Planes make me nervous. M: There's nothing to be frightened of. How many planes fly across the Atlantic every day? W: I've no idea. Hundreds, I suppose. M: And how often do you hear of a crash? Once or twice a year? W: Yes, but aero-planes fly so high and fast that once is enough. M: There are more road accidents per day than air deaths per year. Air transport is really safe compared with road transport. W: I still prefer to go by sea. Ships may not travel fast but as least you can relax. I'd love a trip on a luxury liner like the Queen Elizabeth II. M: It's fine if you're a good sailor, but have you ever traveled far in a rough sea? W: No. I've only been in a boat once. I sailed down the River Thames on a sightseeing tour, but in any case I'd rather be sea - sick than dead. What was said before this conversation?

Answer: M: Are you looking forward to your trip to Canada, Susan?
Problem: W: I'm waiting for a bus. The buses are so full at this time of the day. M: Sure. Where are you going? I don't think this is your way home. W: You are right. I'm going for a walk in the park. M: Going for a walk even after along day's work? W: Yes. I always enjoy walking alone in the park after work. M: I see. Then why not go there on foot? It's not so far from here. W: Oh, no. I hate walking through the streets. What was said before this conversation?
