Which of the following is the main type of question, according to you,  a coach would use to seek further clarification?

The main type of question a coach would use to seek further clarification is an open-ended question. This type of question is designed to encourage a full, meaningful answer using the subject's own knowledge and/or feelings. It's the opposite of a closed-ended question, which encourages a short or single-word answer. Open-ended questions also tend to be more objective and less leading than closed-ended questions.

Here's the step-by-step reasoning:

1. Identify the purpose of the question: In this case, the coach is seeking further clarification. This means they want more information or a deeper understanding of the topic at hand.

2. Match the purpose with the question type: To get more information or a deeper understanding, the coach needs to encourage the other person to talk more and share their knowledge or feelings. This is best achieved with open-ended questions, which are designed to elicit longer, more detailed responses.

3. Conclusion: Therefore, the main type of question a coach would use to seek further clarification is an open-ended question.
