PART I: ESSAY COMPONENT: The first pаrt оf the exаm cоnsists оf аn essay component. Part 1 should be completed in essay format and contain a minimum of 5-6 paragraphs. When answering the question, your goal is to address all parts of the exam question while supporting your argument and sub-claims with evidence (paraphrasing material from the course content). Pick only ONE option to answer the questions below: Option 1: Identify and discuss the purpose and process of the Atlantic Slave Trade. Next, discuss why the status of an enslaved Black individual in the British North American colonies would have declined from an indentured servant to a chattel slave by the 1670s. Option 2: Following Columbus' invasion of the Americas in the 1490s, a European misconception of the native peoples emerged that reduced all indigenous Americans to one monolithic ethnocultural group. In a 5-6 paragraph essay, identify and discuss why the European perception of native peoples is incorrect while considering the scientific theories that account for indigenous peoples' cultural diversity in the Americas. Secondly, examine why some indigenous peoples' belief systems challenge those scientific theories. Option 3: Upon contact, Europeans argued that native Africans and Native Americans were culturally inferior and lacked the trappings of "civilized" society. Examine the assertions covered in the course materials that help us understand why Europeans harbored these assumptions. Finally, examine and discuss some aspects of indigenous American and West African history, societies, and cultures that challenged European presumptions.
