What must be done before validating a review queue?

Before validating a review queue, it's necessary to both pause the review queue and disable auto-refresh. Pausing the review queue ensures that no new documents are added to the queue during the validation process, which allows for a stable and consistent set of documents to be assessed. Disabling auto-refresh prevents the review interface from automatically updating and changing the view, which could lead to confusion or errors in the validation process. By implementing both steps, a user can effectively ensure that the validation is thorough and accurate, leading to reliable results. Thus, the correct approach requires taking both actions prior to validation.
