Final answer:
The quote by Dr. Oswald P. Bronson shows how African Americans were at risk if they opposed Jim Crow laws.
Step-by-step explanation:
The quote by Dr. Oswald P. Bronson appears to show how African Americans were at risk if they opposed Jim Crow laws. The passage states that racial mob violence and discrimination were prevalent in the South during the late 19th century, with the Ku Klux Klan and Jim Crow laws governing much of the region. It also mentions the disfranchisement of black voters and the violence and intimidation they faced for trying to improve their lives or pursue political power. These historical factors indicate that African Americans were at risk if they opposed Jim Crow laws.
