A research coordinator continues with partial results when two of seven sources remain unavailable after retries. Stakeholders later act on a conclusion about one region where the missing sources were the only coverage, believing it was fully researched. What change to the synthesis output best prevents this?

Answer: D — Add coverage annotations showing which findings are well supported and which areas have gaps

Coverage annotations tell readers which findings are well supported and which topic areas have gaps due to unavailable sources. (A) blocks all output over a partial failure. (B) hides the gap behind unsourced content. (C) changes timing, not what the reader can see.
