Answer:
As it shows that settlement houses increased their number during the 1900s decade, a conclusion that the chart supports is that Acculturation and Americanization programs became more popular between 1900 and 1910.
Step-by-step explanation:
The Settlement Movement was founded with the purpose of uniting people and bridging inequalities, and creating physical closeness and social interconnection between individuals of opposite social extraction.
Its main characteristic was the construction of dwellings (called settlement houses) in the poorest neighborhoods, where the less well-off lived together with volunteers from the upper middle class, glad to share their education and knowledge, secondly contributing to the reduction of poverty.
As the chart shows an increase in the number of settlement houses, it can be inferred that americanization and poverty-support programs became more popular during that time.
