A: What do you think is the best way of travelling is?
B: I think aeroplane is by far the best way.
A: Why do you think so?
B: Because it is the fastest and the safest.
A: Of course it is when you are talking about a long distance.
B: That's true. For shorter distance I think I will have to say, car.
A: And why is that?
B: Well, it is quite obvious that you will not find an airport everywhere, but a carparking space is a lot more easier to find.
A: What about bicycles then?
B: Eh... I don't think so. The area I live in is in the mountains. It takes a strong sport-man to ride on those hilly roads.
