The main idea here is how the two types of questions shape the information you get. Open-ended questions invite elaboration, exploration, and detail, helping you understand thoughts, feelings, and the bigger context. Closed questions seek specific pieces of information, often a concise fact or a single data point, which helps you confirm details or move quickly to the next step. In practice, you’d use open-ended prompts to start a conversation or to explore a patient’s experience: for example, “What brings you in today?” or “How have you been coping with your symptoms?” These prompts let the person share their story in their own words. Closed questions are handy when you need a precise answer: “Do you have a fever?” or “Is your pain 7 out of 10 on the pain scale?” They’re efficient for collecting specific information and for confirming details. So the best choice states that open-ended questions invite elaboration and closed questions seek specific information, with open-ended use for exploring and closed use for confirming details. The other options mischaracterize how these questions work or how they’re used, which is why they don’t fit.
