✍️ Sample Proofreading & Editing Questions & Answers
1. Which of the following is an example of a word that is frequently confused?
'Affect' (verb: to influence) and 'effect' (noun: a result) are among the most commonly confused word pairs in English.
2. Which of the following statements has proper punctuation?
In this sentence, "its" (without an apostrophe) is the possessive form of "it," correctly indicating that the collection belongs to the bookstore. "Children's" uses an apostrophe before the 's' to show possession for the plural noun "children," as "children" is already an irregular plural. Options A, C, and D incorrectly use "it's" (meaning "it is") or "its'" (which is not a valid word), and/or "childrens'" (an incorrect plural possessive form).
3. Which word correctly completes the sentence: 'The new policy will ___ all previous guidelines'?
'Supersede' is the only correct spelling — it derives from the Latin 'supersedere' and does not follow the '-cede' pattern.
4. Which of the following is an example of an inconsistency a proofreader should flag?
Inconsistent abbreviation usage — alternating between 'figure' and 'Fig.' — is an editorial inconsistency that should be standardized.
5. What does the proofreading symbol 'eq #' mean?
'Eq #' instructs the typesetter to equalize or even out the spacing in the marked area.
6. What is a house style?
House style refers to the specific set of editorial conventions adopted by a particular publisher, company, or organization.
