I've found this question online as well as the text it refers to.
Answer:
The statement which expresses the central idea of the text is:
A. Walker's accomplishments and views on women's rights were beyond what many people could accept during her time.
Step-by-step explanation:
In this brief text, author Marylou Tousignant lists the many ways and times when Walker defied conventions and prohibitions. From the way she dressed to her education as a doctor, Walker was always ahead of the 19th century society in which she lived. As a child, she was thrown rocks at. As an adult, she was arrested. As a doctor, she was refused by the military. She is now a symbol of courage and determination - a true role model to every woman in the world. But she had to face challenges until the very end of her life - which she did well.
