Final answer:
Families transitioning to Part C services are typically assisted by early intervention service coordinators. Social Security and Medicare chiefly assist the elderly, while the earliest agent of socialization is the family, not a U.S. senator.
Step-by-step explanation:
Families transitioning to Part C services are typically assisted by early intervention service coordinators. These coordinators help guide families through the early intervention process, ensuring that children with disabilities and developmental delays receive the services they need. The role of an early intervention service coordinator involves assessing a child's needs, developing a service plan, and connecting families with the appropriate service providers.Social Security and Medicare are notable for their assistance to the elderly, who are the primary beneficiaries of these programs. They provide financial support and access to healthcare, which is crucial for older adults who are often on fixed incomes and have increased medical needs.Political socialization is influenced by various agents, but a U.S. senator is not typically among them. The earliest agent of socialization is usually the family, where individuals first begin to form their political beliefs and values. Other fundamental agents include religious leaders, teachers, and mass media.
