Identify the correct part–whole mapping to complete the analogy: “‘Flower’ is related to ‘Petal’ in the same way as ‘Book’ is related to …” Choose the component that stands to a book as petal stands to a flower.

Introduction / Context:
This is a part–whole comparison. A petal is one of the constituent parts of a flower. We need the item that corresponds to a book’s constituent units in a similar, discrete sense.

Given Data / Assumptions:

• Petal is a discrete part of a flower.
• Books are composed of pages bound together.

Concept / Approach:
Pick the immediate, discrete component analogous to petal → flower. “Pages” are the obvious discrete units that make up a book, matching the granularity of petal–flower.

Step-by-Step Solution:
1) Determine the required granularity: part → immediate whole.2) Map book → pages (discrete units).3) Select the plural “Pages” to match the idea of many parts forming the whole.

Verification / Alternative check:
Other components (chapters, cover) exist, but “pages” are the fundamental discrete parts, paralleling petals in a flower.

Why Other Options Are Wrong:

• Content: Abstract substance, not a discrete part.
• Author: Creator, not a part of the book.
• Library: Place that houses books, not a component.
• Cover: A component, but not a repeated unit like petals/pages; less parallel.

Common Pitfalls:
Confusing creators or locations with components; ensure consistent granularity.

Final Answer:
Pages
