Final answer:
Children's working conditions in the early 20th century were dangerous and unhealthy, with long hours, low pay, and no support, leading eventually to reform and protective legislation.
Step-by-step explanation:
The working conditions for children in the early 20th century were undeniably dangerous and unhealthy. Youngsters, tasked with operating and cleaning large industrial machinery, were subjected to perilous environments that were hot, boisterous, and fraught with risks of severe injuries such as amputations. Moreover, they faced long work hours with minimal rest, minimal financial compensation, and no social support systems in place. These conditions led to public outcry and eventually the creation of protective legislation, although significant improvements took time to materialize.
