Text structure hierarchy — Book to letter Arrange the following textual units from largest to smallest logical container: Sentence Chapter Letter (character) Book Word Paragraph

Introduction / Context:
This sequence checks understanding of how written material is organized. A book is divided into chapters, paragraphs, sentences, words, and finally letters.

Given Data / Assumptions:

• We arrange from largest container to smallest unit.
• Standard publishing structure is assumed.

Concept / Approach:
Consider nesting: each larger unit contains multiple instances of the smaller one. The hierarchy must preserve this containment property at every step.

Step-by-Step Solution:
Book is the largest container → 4 first.Books contain Chapters → 2 next.Chapters contain Paragraphs → 6 next.Paragraphs contain Sentences → 1 next.Sentences contain Words → 5 next.Words are made of Letters → 3 last.

Verification / Alternative check:
Try reversing any adjacent pair: doing so breaks the container relationship (e.g., words cannot contain sentences).

Why Other Options Are Wrong:
Any sequence where paragraph appears after sentence, or word before sentence, violates containment logic.

Common Pitfalls:
Mixing up paragraph and sentence positions or ignoring that letters are the smallest unit listed.

Final Answer:
4, 2, 6, 1, 5, 3
