Final answer:
The choices made by activists, ordinary people, and authorities in Selma influenced the choices of politicians by bringing national attention to the issue of voting rights and putting pressure on the government to take action.
Step-by-step explanation:
The choices made by activists, ordinary people, and authorities in Selma influenced the choices of politicians by bringing national attention to the issue of voting rights and putting pressure on the government to take action. The civil rights activists, including Martin Luther King Jr., organized marches and protests in Selma to draw attention to the racial injustice in the South. The violent response by authorities, such as the state troopers attacking the marchers on Bloody Sunday, shocked the nation and led to President Johnson asking Congress to pass the Voting Rights Act of 1965.
These actions by activists, ordinary people, and authorities in Selma demonstrated the desire of African American citizens to exercise their constitutional right to vote, and the national response showed the widespread support for voting rights. This public pressure influenced politicians to take action and pass legislation that protected voting rights and addressed racial inequality.
