Which of the following is a true statement about supplements?

• A. They are in-progress events
• B. They add no new information
• C. They are not in-progress events
• D. They replace existing reports

Answer: (C)

Supplements are not in-progress events. They are extra materials that accompany a main report, added after the primary content is prepared to provide additional details, clarifications, or corrections. Because they are finalized when issued, they don’t describe ongoing activities. They also don’t replace the original report; they augment it, offering new information or updates while the original document remains the primary source.
