The average Northerner lost interest in reconstruction once it became reasonably certain that the former slaves:

a) had economic decurity
b)were guaranteed the vote
c) would not be re-enslaved
d)were guaranteed social equality

And your answer is?

It is not d.

To answer this question, we need to understand the historical context and the factors that influenced the attitudes of Northerners towards Reconstruction after the Civil War.

During Reconstruction (1865-1877), the federal government attempted to rebuild and reunite the United States following the end of the Civil War. It aimed to address the issues of slavery and the rights of former slaves, commonly known as freedmen.

To determine when the average Northerner lost interest in Reconstruction, we need to assess the conditions that would have satisfied their concerns. Let's examine each of the options:

a) Economic security: The average Northerner might have lost interest in Reconstruction once they believed that former slaves had achieved economic security. This means that the freedmen were self-sufficient, had access to employment, and were not dependent on charity or public assistance.

b) Guaranteed the vote: Another factor that might have influenced Northern attitudes towards Reconstruction is whether former slaves were granted the right to vote. Suffrage was a crucial issue during this time, as it directly affected political representation and power.

c) Not re-enslaved: Northerners also needed reassurance that the former slaves would not be re-enslaved. Ending slavery was a fundamental achievement of the Civil War, and the Northerners would have been concerned about any attempts to restore this oppressive institution.

d) Guaranteed social equality: Lastly, the average Northerner might have lost interest in Reconstruction if they believed that former slaves were guaranteed social equality. This means that freedmen were treated equally under the law, had equal access to education, public facilities, and were not subject to discrimination or segregation.

Based on these factors, it is likely that the average Northerner lost interest in Reconstruction once they believed that former slaves had achieved economic security, were guaranteed the right to vote, were not at risk of re-enslavement, and were given social equality.

To determine exactly when the average Northerner lost interest in Reconstruction, one would need to examine historical records, primary sources, and the shifting opinions and motivations of the Northern population during that time.
