What option is given when setting up "Include Random Items" in a prioritized review queue?

The correct option for setting up "Include Random Items" in a prioritized review queue specifies that random documents can make up to 20% of the total documents served to reviewers. This functionality is important because it introduces an element of randomness into the review process, which can assist in improving the diversity of document types being reviewed and ensure that reviewers do not become complacent with predictable document flows.

By allowing random documents to be interspersed within the prioritized items, the system encourages a thorough review of all types of documents, rather than only those that are marked as more critical. This feature is particularly useful in large data sets where certain documents might repeatedly dominate the queue, as it helps to mitigate bias in document selection and ensures that reviewers are exposed to a broader context of the material.

Other options either suggest incorrect percentages or involve exclusion of documents, which does not align with the essence of including random items for a more balanced review approach.
