Yоur essаy must be 1,000+ wоrds. Yоur essаy must closely engаge with the assigned text through direct quotation and analysis by incorporating at least four direct quotations, each followed by close analysis of the text’s language and meaning. Your essay should present a compelling, coherent, and specific thesis that is consistently and thoroughly developed. Summarizing the readings or relying on personal reaction will result in a lowered score or a grade of zero. Responses should omit personal reflection in favor of analysis and provide ample support from our readings. Exams that fall short of the minimum word count and/or fail to incorporate textual support (cited quotations) from our readings will suffer a significant grade reduction. Your work will be graded on the quality of your ideas as well as your writing. Criteria for grading include completeness, thoughtfulness, and development and support of a particular argument. Per the plagiarism policy, you must cite ideas that are not your own. You must include MLA format in-text citations. The following deductions will apply: 1) Missing textual support (quotations) from the primary text= -20% of the grade 2) Short of the word requirement= loses points based on percentage short (ex: an essay of 500 words can receive up to 50% credit with 1,000 words required) Prompts (select ONE): 1) Using Fruit of the Drunken Tree, consider how the novel depicts violence on both personal and political levels. How do violence, trauma, and loss shape the lives of individual characters? When and why do trauma, guilt, and coping mechanisms intertwine in the text? Be sure to quote at least four examples from the text. Closely analyze the examples you cite with attention to the relationship between violence, memory, and identity. 2) Using Fruit of the Drunken Tree, consider how the novel explores class and privilege. How and why does Contreras develop the idea of "two Colombias"? How do class differences shape characters' opportunities, relationships, and understandings of the political environment around them? Be sure to quote at least four examples from the text. Closely analyze the examples you cite with attention to the relationship between class, power, and social inequality. 3) Using Fruit of the Drunken Tree, consider how the novel depicts fear and uncertainty. How do secrecy, surveillance, and fear shape the choices that characters make? What does the novel suggest about growing up in an environment defined by fear? Be sure to quote at least four examples from the text. Closely analyze the examples you cite with attention to the relationship between fear, manipulation, and innocence.
