Final answer:
The rule refers to creating a hanging indent for references in academic papers, where the first line starts at the left margin and subsequent lines are indented by 1/2 inch to distinguish between entries.
Step-by-step explanation:
The formatting rule described indicates that for the given content, the first line should begin at the left margin and any additional lines should be indented by 1/2 inch. This format is commonly used in bibliographies and works-cited pages to create what is known as a hanging indent. In academic writing and formatting, particularly in styles like MLA or APA, the hanging indent is used to help differentiate between entries making it easier for readers to find the sources referenced in the paper.
Within Microsoft Word, hanging indents can be easily created by selecting the text and choosing 'Hanging' from the 'Special' options under the 'Indentation' section of the Paragraph menu. Also, it's important to note that adhering to formatting requirements, such as margin size, font selection, header alignment, and paragraph indentation, contributes to the academic rigor and standardization of scholarly work.
