The key answer of exercise 27

Good morning and welcome to our bus tour of the city. We're leaving in ten minutes. So please, sit down as soon as possible. We aren't going to stop at anytime on our sightseeing tour, but you can take photos from the bus. We're going to pass in front of the castle, a national museum and the oldest church i the city. Then we're going to the city centre, where you can see the beautiful old square and the famous park. We're arriving back here after two hours. Any questions?
