The items below describe the production chain for a printed book. Arrange them from raw material to finished product: a) Wood (raw source) b) Book (final product) c) Factory (processing unit) d) Paper (processed material) e) Print (printing action) Choose the correct logical sequence.

Introduction / Context:
This is a process-flow ordering puzzle. We begin with a raw natural resource (wood), move through industrial processing (factory), create an intermediate (paper), apply a transformation (printing), and obtain the finished good (book). Correctly sequencing these steps reflects real manufacturing logic.

Given Data / Assumptions:

• Wood is the raw input for paper pulp.
• A factory processes wood into paper.
• Printing is performed on paper.
• The book is the final printed product.

Concept / Approach:
Use input → process → intermediate → process → final. Each stage consumes the previous stage’s output, guaranteeing a single coherent direction with no cycles or jumps.

Step-by-Step Solution:
Start with a) Wood.Process at c) Factory.Obtain d) Paper.Apply e) Print to the paper.Result: b) Book as the final product.Therefore: a, c, d, e, b.

Verification / Alternative check:
Reversing any step breaks input–output logic (e.g., printing before paper is impossible).

Why Other Options Are Wrong:

• b, e, a, c, d: begins with the finished product.
• c, a, d, e, b: processes before obtaining raw input.
• d, b, c, a, e: uses paper or book before creating them.
• None of these: not needed since a correct chain exists.

Common Pitfalls:
Confusing “print” (an action) with “paper” (a material). Action must follow material production.

Final Answer:
a, c, d, e, b
