Do you know the names of any kingdoms, empires, or countries from Africa up to the 1700s? Do you know of any African leaders from this time period?

the answer to fill in the blank in this question would be the word resource, it is defined as the money, material or people (since human resource is a very valuable good) that a company or a person has at disposition (meaning they can use the resource as they see fit), to be able to complete a task or achieve a goal.  

the correct answer is: the fact that the anti-federalist papers were considered poorly written.
