Which of the following was a major failure of reconstruction? it failed to change the constitution. it failed to give african americans the option to own land. it failed to give african americans the right to vote. it failed to end the bitterness between the north and the south.

Even though there was a lot of bitterness between the North and the South during the Reconstruction era (the period of time right after the Civil War), the biggest failure of that time was that it failed to give African Americans the option to own land. This problem is bigger because its aftermath kept the African American community still under certain oppression by a white majority in the southern states, leading to the need for more reform in the XX century.

the space race was a battle to make advanced technology to get to the moon and to get a better understanding of space.
