Final answer:
MLA style requires double-spacing throughout the entire document, one-inch margins, a header with last name and page number, and centered title without special formatting.
Step-by-step explanation:
The Modern Language Association (MLA) style does not require you to single-space throughout your document. Instead, the proper formatting for MLA style is to double-space the entire paper. This includes the main body of your text, your works-cited page, and any block quotations you may have.
Additionally, you should use one-inch margins on all sides, indent paragraphs one-half inch, and include a header with your last name and page number in the upper-right corner. The title of your paper should be centered and formatted without the use of bold, italics, or quotation marks. Always remember to check with your instructor for any specific requirements they may have, as they supersede general MLA guidelines.
