Drafting Your Lies
Writing well requires iteration - so in order to submit the best possible final report, you will first write a draft of it. Read the final report prompt carefully, and write a 750-word draft.
Make sure you are properly "describing" where your the primary source was found, how it survived for so long, or why no one had found it. Explain how your interpretation reframes the existing knowledge about this event/time in history. Articulate why your fake primary source is reliable in this context. These are all questions you need to be able to address at this stage in the exercise.
