Final answer:
In the hierarchy of substitute decision makers, the individual's spouse is typically first, and the adult children are usually second in line. The order can vary by jurisdiction, and siblings and parents generally follow after the spouse and adult children. Agents of political socialization include family, religion, and education, rather than political figures like senators.
Step-by-step explanation:
The hierarchy of substitute decision makers typically begins with the individual's legal guardian or power of attorney, and following that, the next in line is usually the individual's spouse. However, the exact order can vary by jurisdiction. In many places, after the spouse, adult children would often be considered the next in line to make decisions for a person who is unable to do so for themselves. It is important to note that siblings and parents may also play a role, but they often come after the spouse and adult children in the hierarchy.
As for political socialization and influences on decision-making, agents such as family members, religious leaders, and teachers are typical influencers while a U.S. senator would not be considered a direct agent of political socialization. Adolescents may listen to their parents or peer groups depending on the situation; moral dilemmas may align more with family values, while social choices may be influenced more by peer groups.
