The correct answer is false.
It is false that suburban development and sprawl are a distinctly American phenomenon.
This phenomenon did happen in large cities in the United States. But it is not exclusive of the US. This phenomenon appeared in many large cities in different countries such as London, México City, Paris, Tokyo, Bueno Aires, Beijing, New Deli, Frankfurt, Madrid, Sao Paulo, and many others. Suburban development is a by-product of the increase of population in large cities.
