For what type of query can a fully meets rating be given without an answer displayed?

A fully meets rating can be assigned to a query when the answer is clear, specific, and directly addresses the intent of the user. In the case of a know simple query, these typically seek straightforward, factual answers that do not require an extensive explanation or elaborate results. Since they often relate to easily verifiable information, it is plausible for a well-structured response to fully meet the user's needs without a visible answer being displayed, as the user may already have the information they are looking for from other sources or may already understand the context surrounding that query.

Such queries are designed for direct and unambiguous information transfer, which aligns with the characteristics of fully meets ratings. Hence, it's reasonable to conclude that if the content is considered complete by virtue of its specificity and clarity, a display may not be necessary, allowing the rating to reflect the adequacy of the response alone.
