Which question is used to seek a straightforward request for information?

The selection of a direct question as the correct answer highlights its role in seeking clear and concise information. A direct question is formulated to elicit specific, straightforward responses without ambiguity. This type of question is often characterized by straightforward phrasing that clearly communicates what information is being requested.

In contrast, other types of questions serve different purposes. A primary question usually seeks broad, overarching information that opens up a topic for discussion. Secondary questions tend to follow up on primary questions, digging deeper into a particular aspect rather than seeking initial information. Leading questions are designed to guide the respondent toward a particular answer, often by suggesting a specific viewpoint or assumption, which does not fit the requirement for a straightforward request for information.

Hence, the nature of direct questions makes them ideal for obtaining specific answers, making this option the most appropriate choice in the context of the question asked.
