Final answer:
D) Jane Addams founded the Hull House in 1889 in Chicago, which served as a community center assisting immigrants and the poor through various social and educational programs, thereby playing a pivotal role in social welfare reforms.
Step-by-step explanation:
The Hull House was established by D) Jane Addams in 1889. Located in a poor neighborhood of Chicago, Hull House became a beacon of hope and acted as a community center offering a multitude of services. Jane Addams, inspired by her observations of settlement houses in London, created a space that served needy immigrants through social and educational programs and became a center for sociological research.
Hull House also involved several women college graduates, who were often excluded from other professions, in providing essential services such as medical care, English classes, and hot lunches for factory workers. These volunteers and social workers became a crucial force in the progressive movement, championing causes such as the fight against child labor and the protection of women and children. The legacy of Hull House and its founder contributed to significant reforms in social welfare policies.
