When proofreading a written document, the writer should ensure:

• A. Appendices are used
• B. Endnotes are complete
• C. The memo is in an outline format
• D. The memo follows a consistent format

Answer: (D)

Consistency in formatting is essential when proofreading a memo because a uniform presentation makes the document easier to read, reduces the chance of misinterpretation, and conveys professionalism in official communications. Readers expect a predictable structure—the same font, margins, spacing, and heading style—so they can quickly determine who the memo is for, what it concerns, and what action is required. Appendices or endnotes are only needed when there is supplementary material or formal citations, which aren’t standard in every memo, and using an outline format is not typical for a memo and can disrupt the flow. So, keeping the memo to a consistent format is the best practice.
