Opposition to Child Labor

Opposition to child labor:

A) began in the north, and a child labor law was passed in Massachusetts that required children under 15 who worked in factories to attend school for at least
Three months per year.
B) began in the Republican party platform that voted to ban factory employment for children under 12.
C) caused many factories to move West to avoid the growing number of protections of children.
D) solidified in 1952 by the legislation that created a federal minimum age of 16 for employment, with a maximum number of 20 hours per week.
E) was strongly supported by the children's parents because they wanted their children to stay in school so that they could have a better life.
