I know that this isn't what you're looking for, but the answer is not B. The rebellion brought about a decline in race-based slavery. I know because I took the quiz.
The correct answer is answer C ("To condemn the policies of this predecessor").
In 1956, Nikita S. Khrushchev (a very important figure for the Soviet Union) gave his infamous speech at a closed congress session of the Communist Party. His purpose was to destroy the figure of Stalin by denouncing the abuse of power from the dictator (criticizing his policies of wide-spread mass terror in detail) and also condemn is ineffectiveness at defending the Union from the German Invasion.

The Scopes Trial reveled a split between the scientific and religious community.
In this case, John T. Scopes was arrested. Scopes, a substitute teacher, was arrested for teaching the students about the theory of evolution. This broke a Tennessee state law, which stated that only creationism should be taught. After he was arrested, Scopes was put on trial.
Many members of the science community supported Scopes, as they see the theory of evolution as an important concept in understanding how humans evolved. On the other hand, members of the religious community wanted Scopes punished. This is because his teachings went against their religious beliefs.
