What were the problems with the souther plantation owners' claims that enslaved African Americans had a better life than African Americans working in the North?

The correct answer to this open question is the following.

Although there are no options attached we can say the following.

The problem with the southern plantation owners' claims that enslaved African Americans had a better life than African Americans working in the North was based on the fact that in the North, people were abolitionists and were against the institution of slavery.

In the South, wealthy landlords had slaves and forced them to long for long hours under the sun producing cash crops that had to be traded and exported to Europe. Black slaves lived a difficult life in the South, and that is why they wanted to escape to the North to be free.

Let's put the example of the Underground Railroad.

The Underground Railroad operated before the Civil war. It was not a road at all, but a group of people that wanted to help slaves to other territories where slavery had been abolished. Basically were the Quakers, the group that formally helped African Americans to leave the slavery states.

One figure has the spotlight when talking about helping southern slaves escape to the northern states: Harriet Tubman.

She was a supporter of liberty and always wanted to help black slaves from the south to be free. That is why she escaped from slavery and later help many of them to get to the North before the beginning of the American Civil War.

the correct answer is “opportunity cost”. opportunity cost is what a company misses out because it decided in one option over another one. in this case, the company decided to invest in building a factory so it gave up another possible benefit or profit in order to achieve success with the factory.  

trade-off is not the correct answer since it is a situation in which you accept losing something in return for benefits in other areas.

and finally, consequence is a general term used to accept what it comes when you make a decision. it can be a positive or negative consequence depending if the decision you took was the correct one.
