Final answer:
Longtime residents who stay in gentrified areas often see increased property values, though gentrification generally leads to higher costs of living and can displace original residents.
Step-by-step explanation:
Of the options listed for longtime residents who are able to stay in gentrified areas, the TRUE statement is that there is a potential for increased property values. Gentrification typically involves higher-income residents moving into an area, leading to rising property values. However, it often results in increased costs of living, which can make it difficult for long-term, lower-income residents to remain in the neighborhood. While gentrification can lead to increased cultural diversity, it more commonly displaces original residents and local businesses due to higher rents and cost of living. Improved access to affordable housing is usually not an outcome of gentrification, as this process tends to decrease affordability.
