A. Urbanization

Explanation:

The first half of the 20th century, until the Second World War, is a transition stage between the "primitive" industrial city and the formation of the extensive and multiform metropolitan areas. The dense and compact industrial city model begins to change as soon as the possibilities of intra-urban, collective and private transport are created and expanded.

In the history of the city, the moments and fragments planned and those developed spontaneously or organically are altered and superimposed.

The extensive growth of large cities has not been the only phenomenon of urban change operated throughout the century. The most relevant transformation has been the change of scale experienced in the urban system, producing a process of expansion that has not only overflowed the traditional administrative limits, but has also invaded entire regions.

The revolution in transport, fruit of the irruption, first, of the metropolitan railroads and, later, of the generalization of the use of the automobile, allowed the progressive separation of the residence and the work, generating an unstoppable process of suburbanization.

The dynamics of the metropolis throughout the twentieth century has appeared an infinite growth. However, most urban analysts sensed, already in the mid-1970s, signs of depletion in the growth of large urban agglomerations.
