What does the concept of "revealed by" refer to?

• A. Using authorized sources to gain new insights
• B. Classified information coming from an authorized source into a new document
• C. Reinterpreting existing classified documents
• D. Creating new classifications from scratch

Answer: (B)

The concept of "revealed by" is crucial within the context of derivative classification. It specifically refers to situations where classified information is incorporated into a new document from an authorized source, establishing that the new document retains the classification level of the information it contains.

When information is derived from existing classified materials and then included in a new document, it signifies that the source material, which has been classified, has revealed certain details or insights that must also be protected. This maintains the integrity of the original classification while allowing for the use of that information in new contexts.

While the other options address different aspects of handling classified information, they do not align with the specific meaning of "revealed by." Utilizing authorized sources, reinterpreting documents, or creating new classifications from scratch does not directly capture the essence of how existing classified information is leveraged in new documents in the context of derivative classification.
