The streets in big city are wide as the streets in the country are narrow
The air in the country is clean as the air in a big city is dirty
The nature in the country is beautiful as the nature in a big city is poor
The life in the country isn't so interesting as the life in a big city
People in the country are probably quiet as people in a big city are noisy
The houses in a big city are high as the houses in the countryside are short
