When is the Expro planned to take place?

One: When is the Expro planned to take place?
Man: Hi, Rebecca. I want to talk with you about the date of the Expro.
Woman: OK. Well, I have contacted the entertainment venue centre, and we could book it anytime in the first week of next month. Our chief won’t be back until Wednesday. So...
[pause]
Two: Which room should the man go in? Man: Excuse me, I want to see Mara.
Woman: Oh, sir. She is on the phone. Do you have any appointment?
Man: No, but she did call me for the mistakes of my documents for immigration.
Woman: Yes, I know. You may go to see the Vice Manager in the second room along the alley.
[pause]
Three: Which university’s Students Recruiter will be absent?
Man: Lilian, please give me the new list of the universities, which will be present in the Fair.
Woman: Sorry, sir. The colleagues in headquarter just called to say the participants of this Fair have changed. Concord and Stirling are not sure with their participation. And the representative of Concord is in Africa now, so I guess that he won’t be here in two days.
[pause]
Four: Which will be the most important stuff to be prepared?
Man: Excuse me. I am new here. I want to know where I could get my stationery.
Woman: Oh, you can apply for anything you want at reception. Linda will give what you need. And never forget the pin, which is much more useful than the pencils and notebooks.
Man: Thanks a lot!
