Which of the following best defines 'revision'?

• A. a modification or edit of something
• B. the act of looking over something that one has done
• C. a complete new version
• D. the act of calculating again

Answer: (A)

Revision is the process of making changes to improve a piece of writing or a created work. It centers on modifying or editing the existing material to make it clearer, more accurate, or better organized. This is why it’s the best definition: it focuses on altering what’s already there rather than starting from scratch, simply reviewing, or performing a different task like recalculating. Looking over something you’ve done describes review more than edit, a completely new version implies starting anew, and calculating again isn’t related to editing or refining content.
