Brush techniques

Correct answer: D. Clean damp brush

Explanation: The relevant brush technique is to soften the meeting edge while both colours remain workable. A clean, slightly damp brush can move lightly across that edge and merge the pigments with control, so option D is correct. A dry stiff brush may scratch or disturb the surface, while a colourless pencil and a metal tool are not suitable for gently blending wet paint. Excess water should also be avoided.

Correct answer: C. Paint does not dry and harden in the bristles

Explanation: The governing concept is proper care of painting tools. When a brush is cleaned immediately, wet paint is removed before it dries and hardens between the bristles. This keeps the bristles soft, flexible, and able to hold their intended shape, so the brush remains useful for later work. Cleaning does not darken the colour, dry the paper, or change the size of the painting; therefore, option C is correct.

Correct answer: B. Thin brush

Explanation: The governing concept is selecting a brush according to the size and detail of the area. A thin brush has a smaller tip, so it gives better control near outlines and in narrow spaces; therefore, option B is correct. A wide brush covers large regions but may cross boundaries, while a cloth or roller cannot provide the precision needed for small painted sections. The artist should also match the brush shape and moisture to the required edge and finish.

Correct answer: A. Wide flat brush

Explanation: The governing concept is efficient and even coverage. A wide, flat brush holds and spreads paint across a broad surface, allowing the artist to cover a large area with fewer overlapping strokes; therefore, option A is correct. A very thin brush is designed for details and would leave uneven bands or require excessive time. A dry pencil and pointed pen are drawing tools, not suitable for laying an even painted layer. Consistent pressure and parallel strokes further improve the result.

Correct answer: C. Stroke width and paint deposit remain more even

Explanation: The governing concept is consistent brush pressure. When pressure remains steady, the bristles spread in a controlled way, so the stroke width and amount of paint deposited stay more uniform across the area. This produces an even filled layer, making option C correct. Pressure cannot change a colour’s name, does not make the brush heavier, and does not cause paper to dry instantly.

Correct answer: D. Paint may spread irregularly and spoil the edge

Explanation: The governing concept is brush-tip control. Splayed bristles point in different directions, so they cannot maintain a narrow, predictable contact line. Paint may leak beyond the intended outline or leave an uneven edge; therefore option D is correct. Such bristles do not automatically brighten the paint or harden the paper, and their condition does not necessarily mean they hold more water.

Correct answer: A. Applying colours

Explanation: A painting brush is designed to carry and apply pigment to a surface. The artist can use different brush sizes and shapes to fill areas, make thin or broad strokes, blend colours, and add details. A brush is not a cutting tool, eraser, or measuring instrument; those tasks require different materials. Therefore, applying colours is its main purpose.

Correct answer: A. Smooth blending and soft strokes

Explanation: Soft bristles spread paint gently and evenly on the surface, making them suitable for smooth blending and soft strokes. Cutting paper or carving stone requires specialised tools, not a paintbrush. Exam tip: Choose a soft brush when the effect required is blending or a delicate finish.
