Read the scenario carefully. After tapping "Done Reading", answer the deduction questions.
A bookshelf features five shelves, each capable of holding a maximum of five books. Currently, the bookshelf is empty and will soon be filled with books of varying sizes. The arrangement will follow specific guidelines: the largest book will occupy the bottom shelf, while the smallest book will be placed on the top shelf. The second largest book will be positioned on the second shelf from the bottom, and the second smallest book will take its place on the second shelf from the top. However, due to a design flaw, the manufacturer advises against placing any books on the middle shelf.
