As parental and school influences wane in adulthood, which of the following emerges as a more important socialization agent?

A) Families
B) Political parties
C) Historical references
D) The current presidents
E) Adult peer groups and mass media

As individuals move into adulthood, their socialization becomes more influenced by their peer groups and the media they consume. Political parties may have some influence, but adult peer groups and mass media have a much stronger impact on the values and beliefs of individuals at this stage of life. Families and historical references may still have some influence, but it is not as strong as that of peer groups and media. The current president may also have some influence, but their impact is typically limited to specific political issues rather than broader values and beliefs.
