The concept of “revealed by” (in the security/derivative classification context) includes these two ideas:

  1. Classified information is not clearly or explicitly stated in the source document, but it is still present in a more subtle way.
  1. A reader can deduce the classified information by performing additional interpretation or analysis , even though it is not plainly written.

So when a question asks, “The concept of ‘revealed by’ includes which of the following? (Select all that apply),” the correct choices are the ones that say:

  • “Classified information is not clearly or explicitly stated in the source document,” and
  • “A reader can deduce the classified information by performing additional interpretation or analysis.”

In other words, information is “revealed by” something when it can be inferred or teased out , rather than directly quoted or clearly spelled out.
