The correct answer is An increase in child labor
Children from poor or working-class families had worked for centuries before industrialization, helping with household chores or assisting in family business when they were skilled. The practice of putting children to work was first documented in the medieval era, when parents made their children unwind threads so that they could produce fabric on the loom. Children performed a variety of tasks that were aiding their parents, but were crucial to the family's economy.
