A scenery, meaning a scenic picture, painting or view, always has which of the following essential features?

Introduction / Context:
This question deals with the concept of scenery, especially in the context of art and visual representation. The word scenery may refer to a natural view, a landscape painting, or stage background. The task is to identify which option represents a feature that must always be present in any scenery, regardless of what particular objects it contains. The focus is on what makes a scenery visually and artistically structured, not on specific natural elements such as rivers or mountains.

Given Data / Assumptions:

• The subject is a scenery, that is, a scenic view or artistic depiction of a landscape.
• Options include rivers, mountains, paints and composition.
• We assume scenery can be natural, painted, photographed or stage designed.
• We are asked which feature is always associated with scenery as such.
• The correct answer must apply to any scenery, not only to particular examples.

Concept / Approach:
In visual art and design, composition refers to the arrangement of visual elements within a frame or scene. Whether a scenery contains rivers, mountains, fields, buildings or the sea, there is always some composition: a structured placement of objects, colours and shapes that make the scene meaningful. By contrast, many scenic views do not feature rivers or mountains, and paints are only relevant when the scenery is specifically a painting, not a photograph or real-life view. Composition is therefore the only truly universal feature in the options given.

Step-by-Step Solution:
Step 1: Consider rivers. Many beautiful sceneries contain rivers, but it is easy to imagine vast plains, deserts or urban skylines that have no rivers at all. So rivers are not always present. Step 2: Consider mountains. Some sceneries focus entirely on plains, forests, oceans or city streets without any mountains. Therefore, mountains are not a necessary part of every scenery. Step 3: Consider paints. Paints are used to create painted sceneries, but scenery can also be seen directly in nature or captured in a photograph or digital image with no physical paints involved. Step 4: Consider composition. Every scenery, whether real or represented in art, involves an arrangement of elements within a visual field. This arrangement is what we call composition. Step 5: Recognise that composition is unavoidable; even a simple view of a sky and a horizon line has a certain composition of elements in space. Step 6: Conclude that composition is the only feature among the options that a scenery must always have.

Verification / Alternative check:
Imagine a variety of scenic views: a flat grassland under a blue sky, a seashore at sunset, a crowded city street at night and a forest path. Some may have no rivers, no mountains and no paints involved if they are real views or photographs. Despite this, each has a recognisable arrangement of lines, colours, shapes and objects. This arrangement is precisely what composition means in visual terms. Because composition is inherent in any view or scene, it is always associated with scenery, confirming it as the correct choice.

Why Other Options Are Wrong:
Rivers and mountains are common scenic elements but not universal. Many beautiful landscapes lack one or both. Paints only apply to painted sceneries and cannot be considered essential to every form of scenery.

Common Pitfalls:
Learners sometimes think of typical postcard scenes, imagining rivers and mountains, and quickly pick those options. Others focus on the idea of art materials and choose paints. The key to such questions is to think in terms of what must be present conceptually, regardless of the specific content. Whenever an exam asks what is always associated with a visual concept, composition is a strong candidate because it reflects how things are arranged, rather than which things happen to be present.

Final Answer:
A scenery always has composition.
