Although gentrification can revitalize cities by rehabilitating
residential areas, which of the following problems can be
explained by the type of building renovations shown in the
before and after images?

Higher rents causing displacement of existing residents.

Explanation:

Gentrification is the process of remodeling a neighborhood, street or building to increase its value and attract a population of a higher social status.

This process is highly controversial since the current inhabitants of the area usually cannot bear the costs of continuing to live in the same neighborhood and must move. Residents are sometimes forcibly evicted before remodeling.

I hope this information can help you.
