Verification of truth — necessary attribute: A “scenery” (as a visual scene or landscape) always has what essential feature?

Introduction / Context:
Here, “scenery” refers to a visual scene/landscape or its depiction (e.g., in art or stage design). The question asks for a feature that must always be present, irrespective of the particular content (mountain, river) or medium (painting vs. natural view).

Given Data / Assumptions:

• “Scenery” is about the arrangement of visual elements within a view or representation.
• Specific objects (mountains, rivers) are optional; materials like “paints” apply only to painted representations.

Concept / Approach:
The essential property of any visual scene is that it comprises an arrangement/organization of elements—i.e., a composition. Whether the scene includes mountains, rivers, plains, or cityscapes, there is always a compositional structure (foreground/background, forms, lines, masses, balance).

Step-by-Step Solution:

Verification / Alternative check:
Consider a seascape, forest, desert, or urban skyline; each differs in content, but all have some arrangement of visual elements—hence composition exists in every case.

Why Other Options Are Wrong:

• Paints: Only for artworks, not for natural scenery.
• Mountains / Rivers: Optional elements; many scenes have neither.
• None of these: Incorrect because “Composition” is universal.

Common Pitfalls:

• Equating “scenery” exclusively with mountainous landscapes.

Final Answer:

Composition
