Which of the following best characterizes a closed-ended question?

Closed-ended questions are designed to elicit specific responses, typically in the form of a single word or a brief phrase. This characteristic makes them an efficient tool for collecting straightforward information, such as ‘yes’ or ‘no’ answers, or selecting from predetermined options. The structure of closed-ended questions inherently limits the response spectrum, making them less suitable for elaborative or nuanced discussions.

In contrast, the other options focus on eliciting more extensive and thoughtful responses. Questions that encourage discussion are inherently open-ended, aiming to invite dialogue rather than restrict it. Similarly, those that prompt for detailed answers seek out comprehensive elaborations, and questions that require critical thinking are crafted to engage deeper analytical or reflective reasoning. These qualities are not characteristic of closed-ended questions, which prioritize efficiency and clarity over depth and exploration. Thus, the defining feature of closed-ended questions is indeed their capacity to be answered succinctly, often with just a single word.
