Brush techniques

Correct answer: C. To remove paint trapped near the roots

Explanation: The governing concept is thorough cleaning without damaging the brush. Paint can remain hidden where the bristles enter the ferrule. Gently opening or pressing the bristles outward lets water or mild soap reach that trapped pigment, so option C is correct. The action is not meant to paint or shorten the handle, and forcefully spreading bristles would cause permanent damage.

Correct answer: A. The amount of paint and stroke effect can be checked

Explanation: The governing concept is testing and controlling application before committing to the final surface. A light test stroke reveals how much paint is loaded, how wet the brush is, how strong the colour appears, and what texture the brush produces. Therefore, option A is correct. It does not instantly finish the painting, clean the brush, or alter the paper’s size.

Correct answer: B. Remove excess paint from the brush and slightly dilute the mixture

Explanation: The governing concept is controlling value through brush loading and dilution. If a stroke is too dark, remove excess paint from the brush and add a small amount of water or suitable medium to reduce concentration; then test again. Option B is correct. Adding black, tearing the paper, or dipping to the ferrule would worsen the result or damage the brush.

Correct answer: C. Holding the hand too tightly without support

Explanation: The governing concept is brush control: a relaxed grip, supported hand, and steady movement help produce a clean line. If the hand is held too tightly without support, small muscle tension and involuntary movements can transfer to the brush, creating an unwanted shaky stroke. Therefore, option C is correct. Practice, correct paint quantity, and a comfortable posture generally improve control rather than cause shaking.

Correct answer: D. To keep the movement steadier and more continuous

Explanation: The governing concept is coordinated arm movement in drawing and painting. A long line requires the brush to travel in one direction over a considerable distance. Moving from the shoulder and arm gives a wider, steadier range of motion and reduces the small irregular movements caused by using only the fingers. Thus option D is correct. The other choices concern neither line stability nor the mechanics of making a long stroke.

Correct answer: A. Quick diagonal and changing-direction strokes

Explanation: The governing concept is expressive stroke direction. Fast diagonal marks and changes in direction create visual tension, rhythm, and a sense that the subject is moving. Option A is therefore the best answer. Identical dots and square fills are largely static, while very slow horizontal strokes usually suggest rest or calmness rather than energy. The exact effect also depends on pressure, length, colour, and composition.

Correct answer: B. Soft horizontal and controlled strokes

Explanation: The governing concept is the relationship between mark quality and visual mood. Soft, controlled horizontal strokes provide continuity, balance, and a stable visual rhythm, so option B is most suitable for a calm atmosphere. Sharp broken marks, irregular heavy patches, and strong black diagonals introduce tension, disorder, or forceful direction. Colour and composition also matter, but among the given choices B communicates calm most clearly.

Correct answer: C. Use clearer and more varied brush marks

Explanation: The governing concept is atmospheric depth: nearby objects are normally represented with stronger edges, clearer texture, and more visible variation than distant objects. Using clear and varied brush marks makes foreground surfaces readable, so option C is correct. Removing details, blurring every edge, or using only a light wash tends to weaken texture and can make the area appear less distinct or farther away.

Correct answer: D. The illusion of depth may decrease

Explanation: The governing concept is atmospheric perspective and hierarchy of detail. Background areas usually need softer edges, reduced contrast, and fewer sharp marks so that the foreground remains visually dominant. If the background is rendered with excessive clarity and detail, it competes with nearby forms and may appear too close; consequently, the illusion of depth decreases. Therefore option D is correct, while A states the opposite effect.

Correct answer: A. The surface of the object and the desired effect

Explanation: The governing principle is purpose-based technique selection. An artist first studies the surface or texture to be represented and decides what visual effect is required, such as a smooth wash, a rough texture, a fine line, or a broad mark. These decisions guide brush type, pressure, angle, and speed, so option A is correct. Price, paper brand, and the day of painting do not by themselves determine the appropriate technique.

Correct answer: B. Understanding the stroke effect produced by each change

Explanation: The governing concept is deliberate practice and variable control. Pressure changes the width and density of a mark; the brush angle changes the contact area and character; and speed affects continuity, texture, and variation. Recording samples lets the learner compare these effects and select a suitable stroke intentionally. Therefore option B is correct. The sheet is not mainly for decoration, permanence, or measuring the handle.

Correct answer: A. The hill will appear closer than intended

Explanation: The governing concept is atmospheric perspective: distant forms usually appear lighter, softer, less detailed, and lower in contrast. Very dark, sharp brush marks reverse those cues by creating strong contrast and visual emphasis. Therefore the hill seems to advance and appear closer, making option A correct. Option B would require paler, softer strokes; options C and D are unrelated effects.

Correct answer: B. Large distinct strokes in the foreground and small light strokes in the background

Explanation: The governing concept is linear and atmospheric depth. Objects in the foreground are represented with larger, sharper, darker, and more distinct marks, while distant objects use smaller, lighter, and less defined marks. Thus option B creates a convincing change in distance. Equal marks in A flatten the scene, C reverses the visual order, and D provides insufficient textural variation.

Correct answer: C. The viewer's attention may shift away from the main figure

Explanation: The governing concept is focal-point control and visual hierarchy. A main figure should receive the strongest attention, while surrounding marks should support rather than compete with it. Excessively rough, energetic strokes create visual noise and may pull the viewer’s eye away, so option C is correct. The other choices describe no normal consequence of rough brushwork.

Correct answer: D. While the edge is still damp soften it gently with a clean moist brush

Explanation: The governing technique is controlled wet blending. A cloud edge is easiest to soften while the paint is still damp, because a clean, slightly moist brush can spread and merge the boundary without creating a harsh new mark. Therefore option D is correct. Waiting for days makes correction difficult, and B is obviously damaging; C ignores careful observation and control.

Correct answer: B. Dilute the paint with a suitable medium or water

Explanation: The governing concept of glazing is a thin, translucent colour film through which the underlayer remains visible. If the paint looks too opaque, its consistency or pigment load is too strong, so it should be diluted with the appropriate medium or, where suitable, water. Option B is correct. Thicker paint and more pressure increase coverage, while wetting the lower layer risks disturbing it.

Correct answer: D. Reduce paint load and use a light controlled flick

Explanation: The governing concept is control of paint load, brush distance, and flicking force in splatter work. Too much paint or a forceful movement releases large drops. Reducing the load and using a light, controlled flick produces smaller, more consistent specks, so option D is correct. More paint in C worsens the problem; A is not the primary correction, and B can reduce spread but does not control load alone.

Correct answer: A. The strokes will not follow the direction of the water surface

Explanation: The governing concept is directional brushwork: marks should support the form and surface they describe. A horizontal water plane is usually communicated with horizontal or broken horizontal strokes, especially for reflections and highlights. Long vertical marks conflict with that plane and make the water structure less convincing, so option A is correct. The other options are not normal results of stroke direction.

Correct answer: B. They do not support the building's straight geometric directions

Explanation: The governing concept is directional consistency between marks and form. Buildings are defined by planes, edges, verticals, horizontals, and other geometric directions. Circular swirling strokes ignore those structural lines, so the wall loses visual stability and appears weak or poorly constructed. Option B is correct. The other choices do not explain a structural mismatch caused by brush direction.

Correct answer: C. Restlessness or disturbance

Explanation: The governing concept is that brush character communicates visual mood. Very short, broken, sharp strokes create interruption, tension, and strong visual energy rather than a smooth, quiet surface. Therefore, option C is correct because the calm sky would appear restless or disturbed. Option A would be more suitable for broad, soft, continuous strokes; transparency and depth are properties of medium or composition, not the direct mood created here.

Correct answer: D. Direct most strokes along the direction of the wind

Explanation: The governing concept is directional brushwork: repeated marks arranged along one dominant direction can suggest force and movement. If most strokes flow with the wind, the bending trunks, branches, and leaves appear to be pushed by it, so option D is correct. Vertical strokes would contradict the movement, while dots or uniform trunk thickness do not by themselves communicate wind direction or bending.

Correct answer: A. Natural variety

Explanation: The governing concept is controlled variation. Real leaves differ in size, angle, spacing, and direction, even when they belong to the same plant. Repeating exactly one mark makes the foliage mechanical and reduces its natural variety, so option A is correct. Transparency depends mainly on the paint and water ratio; paper strength and brush length are unrelated to the visual variation of leaf strokes.

Correct answer: B. Clarity of the form will decrease

Explanation: The governing concept is edge control. An object's boundary helps the viewer recognize its shape, so careless strokes that repeatedly cross the edge weaken separation between the object and its surroundings. Option B is correct because the form becomes unclear or visually muddy. Deliberate expressive marks can cross boundaries for a purpose, but uncontrolled crossing does not automatically improve precision, colour purity, or depth.

Correct answer: C. Select a sound brush with a fine tip

Explanation: The governing concept is selecting a tool according to the mark required. A spread or worn brush is useful for irregular texture because its separated bristles make broken marks, but it cannot reliably produce a clean narrow line. Option C is correct: a sound brush with a fine, controlled tip is needed. Extra pressure, more spreading, or more paint would usually make the line wider and less precise.

Correct answer: D. The bristles spread and the tip loses its shape

Explanation: The governing concept is brush maintenance and ferrule care. Dried paint near the ferrule hardens between the bristles, forcing them apart and preventing the hairs from returning to a controlled point. Thus option D is correct: the brush spreads and loses its useful tip. The buildup does not improve handle flexibility, paint brightness, or water capacity; instead, it reduces precision and control over time.
