The proof reader any document including your research paper means to

• A. Remove all punctuation
• B. Increase word count
• C. Change the font only
• D. Check of any spelling or grammatical errors and correct them

Answer: (D)

Proofreading focuses on catching mistakes in spelling, grammar, and punctuation so the writing is clean and professional. When you proofread a research paper, you check for misspelled words, incorrect verb forms, punctuation errors, capitalization inconsistencies, and formatting issues, then correct them. The aim is to refine the text after editing, preserving ideas and structure while ensuring accuracy and readability. The best choice describes checking for and correcting spelling and grammatical errors, which is exactly what a proofreader does; the other options involve removing punctuation, increasing word count, or changing the font, which are not the tasks of proofreading.
