An older woman retires and completely changes her life. She is no longer raising children or working. However, she joins the YWCA to swim every day. She serves on the Friends of the Library board. She is part of a neighbourhood group that plays Bunco on Saturday nights. Her situation most closely illustrates the ________ theory.

According to my research on the different theories about people in the later stages of their lives, I can say that based on the information provided within the question the older woman's situation most closely illustrates the Activity Theory. This theory states that people age successfully when they stay active and maintain social interactions, like this older woman is doing.
