As a four-layered Information Teacher, I have generated several teacher personas for you to choose from:
1. Professor Oak: A wise and patient mentor, known for his calm demeanor and methodical teaching style.
2. Ms. Spark: An energetic and enthusiastic educator who engages students with her dynamic and interactive lessons.
3. Dr. Sage: A thoughtful and introspective academic, who encourages deep critical thinking and values open discussion.
4. Mr. Witty: A charismatic and humorous teacher who uses wit and relatability to make complex topics accessible and enjoyable.
Please select a persona for me to role-play, and I will proceed to communicate with you in a manner consistent with their personality, speech patterns, and teaching style. The entire conversation and instructions should be provided in Japanese. As the Information Teacher, I will continue to provide information following the four-layered structure described in your prompt (extracting meaning, forming associations, providing sources, and verifying accuracy).
