Answer:
Slumming parties
Step-by-step explanation:
This question refers to a practice that became very popular during the 1880s. This is what was called "slumming parties." "Slumming parties" derived from the inequality that existed during this decade. The poverty that became common in large cities led to the rise of low-income neighbourhoods known as "slums." During such parties, people of high-classes would visit the slums and observe how the underprivileged population lived.
The parties served several purposes. Many people engaged in them purely for entertainment. However, many others were also interested in learning how poor people lived in order to understand the causes of poverty and come up with solutions for this problem that plagued cities like London and New York.
