Answer:
1. The machinery was designed for adults is the correct answer.
Explanation:
Working in factories was dangerous for children as there were no government regulations on the working hours. They used to work under dangerous conditions and often lost their limbs while working with machinery. Children were hired because they worked hard for less pay. They used to work for food and boarding, the businesses exploited then by forcing to work for long hours. They worked for little pay and in some cases they weren't paid for their labour. Their labour was just ten to twenty percent of that of an adult. In 1870 there were more than 740,000 children working in the factories.
