Answer: Slavery was an important part of their economy
Explanation:
Southern America at the time relied heavily on plantation farming to produce many goods that they exported to the rest of the world and also the North. Crops such as cotton and indigo were in high demand.
Farming these crops was gruesome work and required hard labor. This is why the South used enslaved people. They also wanted to keep labor costs at a minimum and enslaved people were not paid so slavery kept costs down. It was simply too important to their economy.
Answer:
Whether or not breakfast is provided
Explanation:
An independent variable is the variable in an experiment that is being changed. The dependent variable, by contrast, changes <em>because of</em> the independent variable.
In this case, children are either given breakfast or they are not. Since the scientists are choosing whether or not to give the children breakfast, that is the independent variable.
Thus, the independent variable is whether or not breakfast is provided.
Hope this helps!
