Final answer:
The Progressive Era led to the passage of laws restricting child labor and promoting compulsory education, resulting in a decline in child labor and illiteracy rates.
Step-by-step explanation:
The Progressive Era had a significant impact on child labor. During the early 1900s, local anti-child labor organizations and progressive reforms led to the passage of laws in several states that restricted child labor. While these laws were not always enforced, they did help reduce the number of children involved in paid labor and resulted in a decline in child labor-related accidents. Additionally, the push for compulsory education laws made school attendance mandatory for children, which further decreased child labor and illiteracy rates.
