Step-by-step explanation:
The best suggestion for Noam to improve the length and quality of his students' responses would be option C) Use wait time effectively and wait longer between asking a question and calling for a response.
By using effective wait time, Noam allows students more time to process and think about the question before responding. This gives them the opportunity to formulate more thoughtful and detailed answers.
