Classification — object vs role: pick the pair that is NOT “object : professional associated with making/leading it.”

Introduction / Context:
Three pairs match an object with a professional responsible for creating/editing/leading it. One pair matches an object with its hobbyist/collector, not its creator/editor.

Given Data / Assumptions:

• Newspaper : Editor → edits a newspaper.
• Film : Director → directs a film.
• Book : Author → writes a book.
• Stamp : Philatelist → person who studies/collects stamps, not who makes them.

Concept / Approach:
Distinguish creator/editor roles from enthusiast/collector roles.

Step-by-Step Solution:

Verification / Alternative check:
Stamps are designed/printed by postal authorities, not philatelists.

Why Other Options Are Wrong:
They keep the object→maker/leader relation.

Common Pitfalls:
Equating “associated with” to “created by”; the test is stricter.

Final Answer:
Stamp : Philatelist
