is the binding edge of a book or binds a book together

### Why this is right A book’s **spine** is the narrow edge where the pages are joined or held together. It lies opposite the opening edge, and it is usually the part you see when the book is stored upright on a shelf. ### The concept **Binding** means the way a book’s pages and covers are joined to make a book. The spine is the bound edge; depending on the book, its pages may be sewn or glued there. A **cover** is the protective outer layer, which can include the front and back boards as well as the spine. **Fly leaves** are blank sheets near the front or back of a book, often between the cover and the printed pages. | Part | What it is | |---|---| | Spine | The edge where the pages are held together | | Cover | The outer layer that protects the book | | Fly leaves | Blank leaves near the beginning or end | ### The other options - **A. fly leaves**: These are blank leaves near the cover, not the edge that holds the book together. They may be confused with the pages attached to the cover. - **B. cover**: The cover protects the book, but the spine is the specific edge where the pages are joined. - **D. adb**: This does not identify a standard book part in this context, so it does not describe the binding edge. ### Terms - **Binding**: The method used to join a book’s pages and covers. - **Cover**: The protective outer part of a book. - **Fly leaves**: Blank leaves placed near the front or back of a book. - **Spine**: The edge of a book where its pages are joined. - **ADB**: No standard expansion or meaning as a book part can be identified from this option. ### Remember The spine is the edge that holds the book together; the cover protects it, and the fly leaves sit inside near the covers.
