实用好文，谢谢分享。明白了"open-ended question."

"An open-ended question is designed to encourage a full, meaningful answer using the subject's own knowledge and/or feelings.

It is 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."
