Final answer:
It is true that rural families in the 1920s could access healthcare through the child welfare special service run by the Children's Bureau, especially following the enactment of the Sheppard-Towner Act which funded health clinics and educational programs.
Step-by-step explanation:
The statement that rural families in the 1920s could visit the child welfare special, a service run by the Children's Bureau to provide healthcare, is true. This is contextualized by understanding that during the 1920s, the United States government took steps to improve the welfare and health of its citizens, particularly mothers and children.
The Sheppard-Towner Act of 1921, also known as the Promotion of the Welfare and Hygiene of Maternity and Infancy Act, earmarked $1.25 million for well-baby clinics and educational programs, as well as nursing.
These efforts, alongside other public health campaigns, significantly contributed to reducing infant mortality rates and promoting child health care, especially in rural areas where such services were less accessible.
The Children's Bureau was a key agency in implementing these programs and was influential in advocating for the health and welfare of children across America.
