Which concept is used when the new document states "The process takes three hours to complete" based on the source document?

• A. Derivation
• B. Extension
• C. Modification
• D. Translation

Answer: (B)

The concept of extension is applicable in this context because it involves taking specific information from a source document and applying it to a new document without altering the fundamental meaning or intent of the original information. In this case, the statement "The process takes three hours to complete" reflects an exact detail from the source document. This shows continuity of information, wherein the new document extends or elaborates on the original material without fundamentally changing its nature.

Extension generally refers to retaining the same classification level of the source and using the information as is, which is precisely what is happening here. Each detail in the new document directly corresponds to the content of the source, indicating that it is extending its context and applicability while remaining true to the original data. This practice ensures that the information is still protected and classified appropriately under its original designation.
