Which of the following most directly describes the growth of cities? segregation
urbanization
industrialization
commercialization

Urbanization- the growth of cities, the development of a previously non-populated area.

Explanation:

Sub-urban: A decently sized neighborhood.

Remove the sub, which in this case means 'smaller'

Urban: A large city, take NYC for example.

Segregation: The separation and discrimination of different races and ethnicities- There is the time period[t] of Martin Luther King Jr., you likely heard of it.

Industrialization: The evolvement of man-made technology, for example:

From hand-milked cows, to automatic. This took around six years from when it first was thought of.

Commercialization: Moving from a local business with handmade products, to mass produced products. (I believe, I haven't heard the term in a while)

(Thought I might as well get the points for answering haha)
