Question

what is one reason that the number of children working in factories increased in the late 1800s?
workplaces became safer for children as a result of union work.
children chose factory work over going to school.
many families were living in poverty and needed their children’s income to survive.
adult workers went on strike and forced employers to hire children.

Explanation:

During the late 1800s, industrial - era poverty was widespread. Families often struggled to make ends meet and needed the additional income that child labor provided. Safer workplaces would not necessarily lead to an increase in child labor. Children did not typically choose work over school out of preference. Adult strikes did not force employers to hire children as a common practice.

Answer:

Many families were living in poverty and needed their children's income to survive.
