Final answer:
In the 1870s, both Britain and the United States implemented laws to limit child labor.
Step-by-step explanation:
In both Britain and the United States, several laws were passed in the 1870s to limit child labor.
In Britain, the Factory Act of 1874 further limited the working hours for children and introduced stricter regulations. It reduced the maximum number of working hours per day for children under 14 to 10 hours. Additionally, it required all children aged 10 to 14 to attend school for a minimum of 10 hours a week.
In the United States, various states implemented laws to limit child labor during this time. For example, in 1874, Massachusetts passed a law that prohibited children under the age of 12 from working in factories. Other states also introduced age restrictions and limitations on working hours for children.
