Which term best matches 'a modification or edit of something'?

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

Answer: (B)

The idea here is identifying a word that means making changes to something that already exists. A modification or edit of something is exactly what a revision refers to. In editing, a revision involves altering content to improve it—fixing errors, clarifying ideas, or updating details. The other options describe different actions: looking over something you did focuses on checking rather than changing; a complete new version implies starting from scratch rather than editing; calculating again is simply redoing a calculation. So the term that best fits is revision, which captures the act of making edits to improve something. For example, "The manuscript went through several revisions before publication."
