Answer:
Her parents wanted to protest against segregation laws.
Explanation:
Lorraine Hansberry was an African-American writer. The story from her play A Raisin in the Sun overlaps with her real-life in several elements. So we can learn a lot about her views of the world from it. Starting from one element that doesn`t enlace - family from the story was poor and Lorraine`s family was relatively wealthy. But what was mutual is striving for equal rights. Both families decided to move to all-white neighborhood which cause wrath of the people living there (South side of Chicago) - so racial violence from neighbors. There are African elements - Beneatha`s boyfriend symbolizes Lorraine`s uncle who was a professor of African history and influenced her to take a closer look at her roots. Lorraine was an acknowledged writer - Beneatha wanted to become a doctor (feminist moment). Lorraine`s family didn`t want to just give up and be oppressed, so one of the steps they took was to send her to a largely all-white public school.
