For this topic: Identify the topic Explain the topic and why it is important Write a single multiple choice question addressing this topic Your answer should be a paragraph of at least 4-5 sentences. Please do not just list out names of multiple topics, or just tell me that you found a topic to be really interesting. You may tell me you found this topic especially interesting, but you must demonstrate that you learned about and understand this topic by explaining it clearly. Note that there is not a single answer to this question, this is your chance to demonstrate good knowledge of any topic of your choosing from your work in this unit!
