A、An interview between a customer and a shopping assistant. B、An interview between an airport staff and a passenger. C、A convers

W: (12) Excuse me, sir. Do you have a minute? I am a working staff in this airport. I’d like to have an interview with you on the future improvement of our facilities.
M: I’ve got plenty of time, so just shoot.
W: Wonderful. Are you here taking a flight or meeting someone?
M: I am here transferring from my previous flight to the next one which is due in 4 hours.
W: I see. How often do you travel by plane then?
M: Quite a lot. I guess about 30 times a year including both business trips and holiday trips.
W: Oh. What is your suggestion on improving our facilities inside the airport then?
M: Well. (13) I suggest something like a mini-gym should be built in the future. You know, many people take long flights. They can easily get exhausted. A small gym which includes massaging service would be lovely.
W: That is a good suggestion. Anything else you’d like to see in the airport?
M: Then I would further suggest more green plants should be grown here which can relieve the discomfort of our eyes.
W: I’ll write that down. How about the service on the plane? Anything you want to add to the current service?
M: Er.. I would like to see more varieties of the food offered by the plane and (14) if it is possible, more fruits will be served. The seasonal ones will do.
W: How about the newspapers and magazines? Should we improve on that too?
M: (15) I think so far so good but I do suggest more hot movies be played there.
W: Thank you for your marvelous suggestions.
