The Slave Trade

What were the important source regions for slaves, and where were most of the slaves taken? Whom did the Europeans depend on to obtain these slaves? What does the primary source account reveal about the nature of the slave trade and white attitudes toward blacks in the eighteenth century?
it's a discussion post and we need to answer those question depending on the trade slave part of the chapter. I can send you the part that we need to read so can answer those questions.
