Students may not chat, message, email, or speak to anyone else during this exam. Students may not use artificial intelligence (e.g. ChatGPT) in any way during this exam.

However, some students may be able to answer the question in fewer sentences, and some students may prefer to write more to fully answer the question, and that is okay. Please explain your reasoning/logic. In some cases, there may not be one “right” answer. I am more interested in how you apply the material covered in class than whether you come up with one specific answer to these short answer questions. For multiple choice and true/false questions: select the best response
