Final answer:
Carla should use heading styles such as Heading 1 and Heading 2 to format section titles for the table of contents to auto-generate correctly, with main headings centered and subheadings left-justified.
Step-by-step explanation:
To ensure that the auto-generation tool for a table of contents works effectively for Carla's report on the American Revolutionary War, she should adhere to a structured format by using heading styles such as Heading 1, Heading 2, etc., for her document's sections. These styles help the tool recognize different levels of organization, allowing it to create a hierarchical table of contents accurately.
For example, main headings can be formatted with 'Heading 1' and centered, while subheadings may use 'Heading 2' and be left-justified. Formatting instructions for a professional-looking academic paper include a bolded title page, one-inch margins, double-spacing throughout the paper, paragraph indents of one-half inch, centered bold headings for major sections, left-flushed bold subheadings for subsequent levels, and upper-right corner page numbers.
