gentrification

The correct answer is A. Urban sprawl and crowds moving into the city

Explanation:

The "exurbs" are areas placed outside the suburbs that are less crowded that suburbs and whose residents work in areas that are far from the place where they lived. This term emerged in the 1950s in the U.S. as communities that were rural or semi-rural were created beyond the territory of the suburbs; additionally, the creation of the exurbs was mainly caused by the number of people that move from rural areas or other countries to urban area which is known as urban sprawl. This urban sprawl made cities crowded and also expensive and because of this, people who could afford to house in rural or semi-urban areas created exurbs as an alternative that was less crowded and had more space than suburbs. Therefore, the factor that led to the creation of exurbs was the urban sprawl and crowds moving into the city as this motivated people to create communities in "rural areas" that were still close to the city but were not as crowded as suburbs.

new communications technology has affected the way social movements are organized because nowadays, social movements rely on social networks and the media to get different people with a similar way of thinking in contact, and thus, get them to mobilize for a greater cause.

individuals only participate in collective action when they feel identified with it. is in this aspect that social media becomes relevant, because it guarantees communication among all individuals and organizes the social actions that are going to be carried out, i.e., the social movements.

in addition, being covered by the media is important to validate the message and make it relevant in the social agenda, as well as to reach more people who can share interests, appealing to public sympathy for their cause.

in conclusion, it is by social networks and social media that social movement is given birth; by connecting different individuals with similar ideas and organizing them to mobilize for a greater cause.
