Answer:
federalism and limited gorvernment
Explanation:
Some examples of this were the Fugitive Slave Act, Preston Brooks's attack on Charles Sumner, and the Dred Scott decision (the part of it which said that African Americans could never be citizens). None of these events tangibly hurt the North or the South.
The
Transatlantic slave trade radically impaired Africa's potential to
develop economically and maintain its social and political stability.
The arrival of Europeans on the West African Coast and their
establishment of slave ports in various parts of the continent triggered
a continuous process of exploitation of Africa's human resources,
labor, and commodities. This exploitative commerce influenced the
African political and religious aristocracies, the warrior classes and
the biracial elite, who made small gains from the slave trade, to
participate in the oppression of their own people. The Europeans, on the
other hand, greatly benefited from the Atlantic trade, since it allowed
them to amass the raw materials that fed the Industrial Revolution to
the detriment of African societies whose capacity to transform their
modes of production into a viable entrepreneurial economy was severely
halted.
The correct answer in my opinion would be that D is the most important factor here. But this question is quite tricky.
We can surely say for example that literature, organized schools and a hierarchy of priests are not something that constitute a civilization. Organized schools appeared to late, not every civilization had literature and having only a hierachy of priests is not enough to say you have a civilizaton.
Labor has been divided in pre-civilization hunter-gatherer societies as well.
For that reason I'd say the correct answer is D - more food than is needed for survival. Having this, the people in a certain group can focus on other things.
