Brush techniques

Correct answer: B. The desired form, texture, and mood

Explanation: The governing concept is purposeful selection of technique. A brush method should serve the visual result required in the painting: its form, surface texture, line quality, and emotional mood. The most expensive brush is not automatically suitable, and a favourite colour or a number on the paper gives no information about the mark needed. Therefore, option B is correct because technique must be linked to artistic intention and the desired effect.

Correct answer: B. The stroke width and texture change

Explanation: The governing concept is the relationship between brush angle and bristle contact. Holding the brush upright usually allows a smaller contact area and a finer mark, while lowering or tilting it can spread more bristles across the surface, producing a broader or different-textured stroke. The colour name, paper size, and actual brush weight do not change because of the angle. Therefore, option B is correct.

Correct answer: A. Gradually reduce pressure

Explanation: The governing concept is pressure control during a continuous brush stroke. Begin with slightly greater pressure so that more bristles contact the surface and make a thicker mark, then gradually reduce pressure while moving forward. Fewer bristles touch the surface, so the line tapers to a thinner end. Stopping creates a blot, adding water changes paint consistency rather than reliably controlling width, and changing the handle is irrelevant. Thus option A is correct.

Correct answer: A. A slightly rough surface

Explanation: Dry brushing works by leaving a small amount of relatively thick colour on the raised parts of a surface. A slightly rough surface has small irregularities that catch the bristles and reveal broken, textured marks, so option A is correct. Smooth glass gives little grip, a wet surface spreads the paint, and an oily surface prevents dependable adhesion.

Correct answer: B. Better control over fine details

Explanation: The governing principle is that a limited paint load gives greater control over the amount and placement of colour. Keeping paint mainly at the tip supports precise marks and prevents excessive spreading, so option B is correct for fine details. It does not instantly cover a large area, directly dry the paint, or make the brush heavy; those results do not follow from tip loading.

Correct answer: C. Light circular strokes on a damp surface

Explanation: Soft cloud edges depend on gradual transitions rather than sharp outlines. Light circular strokes on a damp surface distribute the pigment gently and allow the edge to fade into its surroundings, so option C is correct. A hard dry line creates a definite border, heavy pressure deposits too much colour, and square strokes are not suited to rounded, soft cloud forms.

Correct answer: D. The next stroke was applied after the first one dried

Explanation: A dark edge is commonly caused by uneven drying and pigment collecting at the boundary of a stroke. If a new wet stroke is placed beside a partly dry or dry stroke, it re-wets the edge and creates a visible darker line, so option D is correct. Brush size, paper whiteness, and handle length do not normally create this drying boundary effect.

Correct answer: A. More at the start and less at the end

Explanation: The governing idea is to match brush pressure with the natural taper of a branch. A branch begins thicker near the trunk and narrows toward its tip, so pressure should begin stronger and gradually decrease, making option A correct. Constant heavy pressure produces an unnatural thick mark, increasing pressure makes the tip wider, and irregular pressure removes control from the stroke.

Correct answer: B. Making thin straight lines

Explanation: A flat brush has a broad face for wider marks and a narrow edge that can be turned onto the surface for controlled, thin strokes. Therefore, option B is correct: the edge is useful for making thin straight lines or narrow details. It is not an efficient tool for washing a very large area in that position, and it cannot safely open bottles or erase paper.

Correct answer: C. A round or flower-like mark

Explanation: The governing concept is controlled brush movement: pressing spreads the round brush hairs, and a slight rotation distributes them around a central point. This can create a rounded, petal-like, or flower-like mark, so option C is correct. A long straight line requires a different pulling motion, an empty circle is not the usual result, and a brush should not cut the paper.

Correct answer: D. Touching the tip with equal pressure and spacing

Explanation: Controlled dot patterns depend on repeatable contact, pressure, and spacing. Touching the surface with the brush tip using nearly equal pressure and intervals produces dots of similar size and a regular rhythm, so option D is correct. Random pressure and colour create inconsistency, dragging makes lines, and excess water causes uncontrolled spreading rather than clear dots.

Correct answer: A. By making thin intersecting lines in two directions

Explanation: The governing concept is cross-hatching: repeated thin lines are placed in one direction and then crossed by another set of lines. Their intersections build a darker, denser visual texture. Therefore, option A is correct. A single circular stroke does not create crossed marks, flowing colour creates a wash rather than a line texture, and a blank surface creates no texture at all.

Correct answer: B. Relax the grip and keep the wrist flexible

Explanation: The governing concept is relaxed brush handling. A loose grip and flexible wrist allow the arm and hand to move smoothly, producing natural variation instead of mechanical marks. Option B is correct because it directly changes the painter’s movement and pressure. Changing the bottle or paper does not solve stiffness, while cutting the brush damages the tool and reduces control.

Correct answer: D. Soften the hard boundary slightly

Explanation: The governing concept is edge softening. A slightly damp, clean brush can reactivate or lift a small amount of watercolour at the boundary, allowing the hard line to merge gently into the surrounding area. Option D is correct. The purpose is not to remove all pigment or thicken it, and careless pressure would risk damaging the paper rather than improving the edge.

Correct answer: B. A two-colour blended effect in one stroke

Explanation: This method is called double loading or two-colour loading. When two colours occupy opposite edges of a flat or suitable brush, one continuous movement can deposit both colours, creating a two-tone or blended decorative stroke. Therefore option B is correct. It does not make a paper cut, guarantee a dry line, or restrict the mark to only one colour.

Correct answer: C. Edges may become uneven and uncontrolled

Explanation: The governing concept is brush condition and mark control. Splayed bristles do not meet as one organized tip, so they deposit paint unevenly and make a clean, predictable edge difficult to achieve. Option C is correct. They do not straighten a stroke or mix colour automatically, and the condition of the bristles cannot make the paper stronger. Replacing or cleaning the brush may restore control.

Correct answer: D. It allows checking pressure, colour and water amount

Explanation: The governing concept is testing and planning before committing a mark. A practice stroke reveals how pressure, brush angle, pigment strength and water content will appear on the surface. Option D is correct because this preview helps the artist adjust the mixture or movement before repeating it on the final work. It cannot change the title, increase paper weight or make an old brush new.

Correct answer: A. Slight variation in line length, direction and spacing

Explanation: The governing concept is controlled variation in repeated brush marks. Real grass blades differ slightly in length, angle, spacing and grouping, so small purposeful changes make the painted cluster appear lively and natural. Option A is correct. Identical lines look mechanical, a single thick band loses individual blades, and round dots do not describe the directional structure of grass.

Correct answer: B. A curved line with continuous light pressure

Explanation: The governing concept is pressure control combined with a flowing direction. A thin vine is best represented by moving the brush along a continuous curve while applying light, steady pressure; this keeps the mark narrow and graceful. Option B is correct. Heavy pressure and a flat brush create a broad band, while dabbing produces separate spots rather than a connected stem.

Correct answer: D. Leave a small light stroke or dot on one side

Explanation: The governing concept is highlight placement in form modelling. A small light stroke or dot on the side facing the light represents reflected light and helps the viewer read the fruit as rounded and glossy. Option D is correct because it creates a focused bright area. The other choices either flatten the form, add an irrelevant outline, or make the surface uncontrolled.

Correct answer: A. Enough moisture for smooth flow without dripping

Explanation: The governing concept is controlled paint flow. A thin outline needs enough moisture to keep the pigment moving continuously, but not so much that the colour spreads, pools, or drips. Option A provides that balance. Excess water causes running, a dry brush makes broken marks, and clean water alone cannot create a coloured outline.

Correct answer: B. The brush lacks enough colour or moisture

Explanation: The governing concept is continuous brush loading. A thin line breaks when the brush does not carry enough pigment or moisture to maintain contact with the surface. Option B is therefore correct; reloading the brush or adjusting its moisture can restore a steady mark. Paper colour, a shiny handle, and straightness do not normally interrupt paint flow.

Correct answer: C. Longer bristles can hold more colour for a longer flowing stroke

Explanation: The governing concept is the relationship between brush construction and mark-making. Longer bristles generally hold a larger paint load and can release it over a longer distance, helping produce an extended, flowing stroke when pressure is controlled. Option C is correct. Bristle length does affect performance; it does not change paint colour or cut the paper.

Correct answer: D. Use a small controlled brush with limited moisture

Explanation: The governing concept is tool and moisture control according to the working area. A small brush deposits less liquid and allows precise movement, while limited moisture reduces bleeding beyond the intended boundary. Option D is correct. A large wet brush, dropped paint, and soaked paper all increase uncontrolled spreading rather than preventing it.

Correct answer: B. Use light pressure with fewer strokes

Explanation: The governing concept is gentle layering over a dry paint film. Repeated rubbing or excessive water can reactivate, disturb, or lift the underlying colour. Option B is correct: use light pressure and make only the necessary number of passes, allowing the new stroke to sit on the surface. Scratching with the ferrule would damage the paper.
