Final answer:
Child labor became commonplace during the Industrial Revolution due to children's vulnerability to exploitation, their suitability for specific tasks, and the desire to reduce labor costs.
Step-by-step explanation:
Child labor became commonplace during the Industrial Revolution for several reasons. One reason was that children were less likely to join a union compared to adults, making them easier to exploit for long hours and low wages. Additionally, children could perform certain jobs that adults were not able to do due to their small size, such as working in coal mines or textile mills. Lastly, children could be paid significantly less than adults, making them attractive to factory owners who wanted to reduce labor costs.
