Final answer:
The open-ended question from the provided examples is number 2, "What features are important to you?" as it requires a more in-depth, personal response compared to the other options, which can be answered with a simple "yes" or "no" or a choice between two options.
Step-by-step explanation:
An open-ended question is designed to encourage a full, meaningful answer using the subject's own knowledge and feelings. These questions are the opposite of closed-ended questions which can be answered with a simple "yes" or "no." Open-ended questions attempt to make the person respond with more than a one-word or short-phrase answer.
From the examples provided, the question that is an example of an open-ended question is number 2: "What features are important to you?" This question cannot be answered with a simple "yes" or "no" and requires the participant to provide a more detailed response, expressing their own opinions and preferences.
Questions like "How do you plan to use your college education?", "What interests you about this job?", or "What should people know about this subject that may be overlooked?" are also examples of open-ended questions because they require essay-type responses that cover personal beliefs, goals, or feelings.
