Find the odd book component (whole vs parts): Select the option that denotes the complete entity rather than a constituent part or section.

Introduction / Context:Hierarchy/part-whole reasoning is a staple in verbal classification. A book is the complete artifact, while pages, chapters, and an index are components or sections that belong to the structure of a book. Mixing whole with parts creates an unambiguous odd-one-out based on granularity.

Given Data / Assumptions:

• Book: the entire compiled work.
• Pages: the individual leaves/sheets on which content is printed.
• Chapters: major divisions/sections within the book.
• Index: back-of-book alphabetical locator for topics/pages.

Concept / Approach:Apply part-whole classification. Three entries refer to components contained by a book; one entry refers to the container/whole that contains those components. The granularity mismatch (whole vs parts) identifies the outlier.

Step-by-Step Solution:

Verification / Alternative check:Think of assembly: one compiles chapters and pages (and prepares an index) to produce a book; the direction of composition confirms the hierarchy.

Why Other Options Are Wrong:They each denote a constituent element that exists only as part of a book (or similar compiled work).

Common Pitfalls:Do not be distracted by where the index appears (front/back); location does not change its status as a component.

Final Answer:Book
