A properly marked source document states a location is Confidential. What concept determines a new document's classification if it states the location will be in Seattle?

• A. Contained in
• B. Derived from
• C. Extrapolated from
• D. Referenced in

Answer: (A)

The correct answer, Contained in, relates to how the classification of information is managed when creating new documents based on existing source materials. When a source document clearly marks certain information as classified—such as a location being labeled as Confidential—any reproduction or summary that includes that specific classified information must follow the original classification guidance.

In this case, since the new document explicitly states that the location is in Seattle and this information originates from a source document classified as Confidential, the new document also assumes that same classification level due to the content being explicitly contained in the previous document. The principle of "contained in" underscores that any new documents including classified details must inherit the classification of their source.

The other options do not accurately convey the concept applied here. "Derived from" would imply that the new document is based on the classified material in a way that might produce different or less sensitive information, which is not the case here since it is directly reproducing a specific classified element. "Extrapolated from" suggests drawing conclusions or making assumptions that may not explicitly match the original classification. "Referenced in" indicates a general mention without conveying that the information is included in the newer document in a way that demands a reclassification, which is not applicable since the new document
