What should a writer do if new information arises after the report is completed?

When new information emerges after a report has been finalized, adding a note or an addendum to address the new information is the most effective approach. This method allows the writer to acknowledge the updated data while maintaining the integrity of the original report. It ensures that all relevant information is presented to the reader without necessitating a complete rewrite of the document, which can be time-consuming and may lead to inconsistencies if revisions are not carefully made.

Including an addendum is especially useful because it provides a clear distinction between the original content and the new information, allowing readers to evaluate the updated context without confusion. This is particularly important in professional settings where accuracy and up-to-date information are crucial for informed decision-making.

The other options do not address the need for accuracy and clarity. Ignoring new information can lead to misinformation and compromise the credibility of the report. Rewriting the entire report may be unnecessary and inefficient, especially if the new information is minor. Presenting the new information in a separate document could result in fragmentation of the findings, making it harder for readers to access the most current and coherent conclusions. Thus, adding a note or an addendum effectively balances the need for comprehensive information with the practicality of maintaining an organized report.
