Difficulty: Easy
Correct Answer: 4, 3, 2, 5, 1
Explanation:
Introduction / Context:
This sequencing problem asks you to order stages from a raw natural source to a finished “book”. Understanding industrial processing chains helps eliminate distractors that backtrack or skip prerequisites.
Given Data / Assumptions:
Concept / Approach:
The chain follows extraction → primary processing → intermediate → finished material → fabricated good.
Step-by-Step Solution:
1) 4 Jungle provides trees.2) 3 Timber is cut/seasoned wood.3) 2 Pulp is produced by chemical/mechanical pulping.4) 5 Paper is made from pulp.5) 1 Book is printed and bound from paper.
Verification / Alternative check:
Any sequence that places “book” before “paper” or “pulp” violates manufacturing order; placing “jungle” after “timber” is backwards.
Why Other Options Are Wrong:
(a) Ends with forest; production does not revert to raw source.
(b) Starts at pulp; missing timber first.
(d) Starts at paper; ignores pulp and timber.
(e) Places pulp directly after forest skipping timber.
Common Pitfalls:
Confusing raw material with semi-finished stages; ignoring that each stage is prerequisite to the next.
Final Answer:
4, 3, 2, 5, 1
