Take the following as truth: However, an oral briefing may be used, for example, when GAO (1) determines that further work is not warranted; (2) provides information that is readily available to the public, such as that in Inspector General reports; or (3) develops a summary of previously issued GAO products that does not contain any new findings, conclusions, or recommendations.
Then the following statement: "An oral briefing may be a way of telling somebody off." is true, false, or inconclusive?
