Tanya: Look at the picture. What's there in the first picture?
Alex: There is a motorcycle.
Tanya: And there's a car in the second picture, isn't there?
Alex: Certainly.
Tanya: As far as I know both vehicles have engines. Is there any difference between the types of engines?
Alex: Well, let me think. If I'm not mistaken, a motorcycle has an air-cooled engine and there's a water-cooled engine in a car.
Tanya: Are there any other differences?
Alex: Yes, of course. Water-cooled engines always have a radiator. But there's no radiator in the motorcycle.
Tanya: You mean air-cooled engines never have a radiator.
Alex: You are absolutely right.
