The election of Andrew Jackson dramatically changed the US for several different reasons including:
1) He was an advocate for the "average citizen"- Andrew Jackson was dubbed the "Champion of the Common Man." He received this title because he was not an inherently wealthy man nor was he part of a family that was consistently in politics. Rather, he came from humble beginnings. This story inspired many American citizens.
2) His policies resulted in increased democracy in the US- Jackson helped to get rid of property qualifications and other restrictions to ensure that white farmers had the right to vote, regardless of how much property they owned.
The answer is B. Martin Luther King Jr., the leader of the Civil Rights Movement, wished to end policies that encourage racial discrimination. He wanted both white people and black people to get along and to be equal.
