What are items such as the cover, title page, and table of contents referred to as?

The correct term for items such as the cover, title page, and table of contents is "front matter." These components serve as the introductory section of a document or book, providing essential information that prepares the reader for the main content. The cover provides the first visual impression and includes the title and author, while the title page formally presents the book's title and other relevant details, such as the author’s name and publication date. The table of contents offers an organized listing of the major sections or chapters, allowing readers to navigate the work easily. This structured arrangement at the beginning of a document helps establish context and guides the reader's understanding of what to expect.

The other choices refer to different sections of a document. The main content typically refers to the core material or arguments presented in the document. Back matter includes supplementary materials found at the end, such as an index, bibliography, or afterword. Appendices contain additional information that supports the main content, often including detailed data or supplementary material that is referenced within the main sections but is not integral to the main narrative.
