Still life drawing

Correct answer: C. The curved surface reflects light along a directional band

Explanation: The governing concept is specular highlight on a curved, glossy form. A round vessel reflects a light source across a changing area of its surface, so the bright reflection can stretch into a long band that follows the vessel’s contour. Option C is correct. A broken edge, wet paper, or an inward-moving shadow does not explain a directional highlight on polished form.

Correct answer: B. The small object's form and identity may become unclear

Explanation: The governing compositional concept is overlap used with recognition. Overlapping objects can communicate front-and-back order and create depth, but enough of each important object must remain visible for the viewer to identify it. If too much of a small object is covered, its contour and characteristic features disappear, so option B is correct. Excessive overlap does not always improve depth, make another object transparent, or remove shadows.

Correct answer: B. Because overall shape and proportion must be established first

Explanation: The initial block-in is a planning stage in which the artist lightly places the overall silhouette, major masses, proportions and relationships of the still life group. If tiny details are drawn first, an incorrect large form may remain unnoticed and the final drawing can become unbalanced. Option B is correct because accurate structure must precede refinement. Details are added later; they are not permanently unnecessary, and a pencil can render them.

Correct answer: C. The scale of measurements will become inconsistent

Explanation: Sight measurement depends on comparing every dimension with one fixed reference, such as the width of a particular object. If that unit is changed halfway through, widths, heights, distances and angles are no longer based on the same scale, so proportional relationships become unreliable. Option C is correct. Changing the unit does not automatically sharpen objects, increase tonal contrast or alter the physical length of a cast shadow.

Correct answer: A. Checking the vertical relationship of different points

Explanation: The governing concept is alignment in observational drawing. A plumb line is an imagined or lightly held vertical reference; it lets the artist compare the top, bottom, and side points of separate objects on the same vertical path. Therefore, checking vertical relationships is correct. Texture, shadow softness, and paper centre are different concerns and are not measured by a plumb line.

Correct answer: B. Internal proportion

Explanation: The governing concept is internal proportion: the relationship between parts within one object. Even when the bottle’s overall height is correct, placing the shoulder too low changes the relative heights of the neck, shoulder, and body. Thus internal proportion is incorrect. Local tone concerns light and dark, background balance concerns the surrounding composition, and cast-shadow direction concerns illumination.

Correct answer: A. Object placement or size is incorrect

Explanation: The governing concept is negative-space observation. Empty areas between and around objects form shapes whose angles and widths depend on the objects’ placement and size. If those empty shapes do not match the reference, the object boundaries, scale, or spacing have probably been drawn incorrectly. Lighting, paper smoothness, and pencil hardness may affect rendering, but they do not change the measured shape of negative space.

Correct answer: B. Move one or more objects forward or backward

Explanation: The governing concept is spatial depth through placement and overlap. If all bases sit on one straight line, the objects can appear flattened and arranged side by side. Moving one or more objects forward or backward creates different spatial levels; overlap can then clarify foreground and background. Equal darkness, erased outlines, or a dark background do not establish reliable positional depth.

Correct answer: B. Crooked and unstable

Explanation: The governing concept is structural axis. The central axis establishes the overall direction and balance of a symmetrical or nearly symmetrical vase; if it tilts, the vessel appears to lean even when its outer curves are carefully drawn. Therefore option B is correct. Transparency and shininess are surface qualities, and a correct contour alone cannot cancel an incorrectly tilted axis.

Correct answer: B. A very flat ellipse

Explanation: The governing concept is perspective: a circular opening is represented as an ellipse when viewed obliquely. At eye level, the line of sight is nearly parallel to the opening, so the circle is seen almost edge-on and its minor axis becomes very small. Therefore, option B is correct. A wide ellipse occurs when the opening is well above or below eye level, while a vertical ellipse would not describe this horizontal circular rim.

Correct answer: A. The cylinder structure is inconsistent

Explanation: The governing concept is structural perspective. The top and bottom rims of one upright cylinder belong to the same form, so their ellipses must share a consistent orientation and minor-axis direction. If the axes tilt differently, the drawing gives conflicting spatial information and the cylinder appears twisted or incorrectly constructed. Thus option A is correct. Lighting changes tonal values, not the geometric alignment of the rims; distance and background darkness do not create opposite axis directions.

Correct answer: B. Lighter or less prominent according to observation and light

Explanation: The governing concept is careful observation of form, overlap, and line weight in still life. The far half of a bowl’s rim is often visually weaker because it is farther from the viewer, partly turned away, or affected by the bowl’s interior and lighting. It should therefore be made lighter or less prominent when observation supports that treatment, so option B is correct. It is not always erased, made straight, or automatically darker than the near edge.

Correct answer: B. Perspective diminution

Explanation: The governing concept is perspective diminution: receding surfaces usually appear progressively smaller as they move away from the viewer. If the near and far faces of a box are drawn with equal width, that reduction in apparent size disappears, so the sense of depth and perspective becomes weak. Therefore, option B is correct. Texture, a highlight, and local tone depend mainly on surface characteristics or lighting, not on the relative narrowing of receding faces.

Correct answer: B. The terminator is an internal light-shadow boundary while the contour is the outer boundary

Explanation: The governing concept is the separation of form boundaries from tonal boundaries. The outer contour is the visible outside edge where the fruit meets the background. The terminator is an internal transition on the fruit’s surface, marking where direct light gives way to the shadow family; it is not the shadow cast onto the ground. Therefore, option B is correct. A highlight is only a bright reflected area and is not a contour.

Correct answer: B. By the direction and height of the light source

Explanation: The governing concept is cast-shadow construction from the light source. The shadow projects away from the light: changing the source’s direction changes the shadow’s direction, while lowering the source generally makes the shadow longer and raising it makes the shadow shorter. Thus option B is correct. Object colour, paper texture, and pencil hardness may affect appearance or rendering, but they do not establish the shadow’s geometric path and length.

Correct answer: A. Because light spreads more around the edge

Explanation: The governing concept is the softness of a cast-shadow boundary. Near the contact point, the blocking object is close to the surface, so the shadow edge is usually relatively sharp. Farther away, light from an extended source can spread around the object and partially illuminate the boundary, producing a softer transition. Therefore, option A is correct. Paper thickness, pencil behavior, and a change in object colour do not explain this optical effect.

Correct answer: A. The sense of contact and weight will weaken

Explanation: The governing concept is the contact shadow: the darkest value usually appears close to the point where the object touches the ground because that area receives the least reflected light and visually anchors the form. If the darkest mark is moved far away, the object may seem to float and its weight or contact becomes unclear. Therefore, option A is correct; the other choices do not describe the effect of misplaced shadow density.

Correct answer: B. The object's volume may look fragmented and patchy

Explanation: The governing concept is tonal grouping, or massing the major light and shadow areas before adding details. A solid form is read through connected value families that describe its planes and roundness. When every small change is isolated, the eye reads separate patches instead of one continuous volume, so the object can look broken, mottled, or flat. Option B is correct; composition and perspective are not automatically improved by extra tones.

Correct answer: B. Lost edge

Explanation: The governing concept is edge variety based on value relationships. When an object and its background have nearly the same lightness or darkness, the separating contour loses contrast and seems to disappear; this is called a lost edge. Option B is correct. A hard edge remains sharply visible, an axis line indicates direction or symmetry, and a contact shadow is the dark area where the object meets the supporting surface.

Correct answer: A. All forms may appear unclear and blurred

Explanation: The governing concept is edge control. Soft edges are useful for gradual turning surfaces, atmospheric recession, and reduced emphasis, but they must be balanced with some clear edges. If nearly every boundary is softened, adjacent forms lose separation and the drawing becomes visually weak, vague, or blurred. Option A is correct; softness cannot by itself make metal shinier, improve perspective accuracy, or correct symmetry.

Correct answer: A. Vary their placement in depth, their tilt, and their value contrast

Explanation: The governing principle is variety within unity. When two objects have nearly equal heights, the composition can gain interest through differences in depth, tilt, spacing, silhouette, and tonal contrast. Option A introduces these controlled differences while preserving visual harmony. Making the objects identical creates monotony; merging contours confuses their forms; and removing shadows weakens depth and grounding.

Correct answer: D. The geometric relationship between light and shadow will be unconvincing

Explanation: A cast shadow is a projection produced when the object blocks rays travelling from the light source. Its main direction should therefore extend generally away from the light. If the long axis points elsewhere, the light-shadow geometry conflicts and the scene becomes visually unbelievable. Option D is correct; shadow direction does not directly change local colour, improve roundness, or clarify texture.

Correct answer: A. Errors in shape, negative space, and value balance

Explanation: Turning a drawing upside down interrupts habitual recognition of the depicted objects. The artist then sees abstract relationships of shape, empty space, proportion, and value more clearly, making structural imbalance easier to notice. Option A is correct. An upside-down review cannot reveal object-name errors, pencil brand, or paper price because those are not visual construction problems in the drawing.

Correct answer: A. Keep both ellipses on the same central axis

Explanation: In still-life construction, the upper and lower elliptical rims belong to the same cylindrical or rounded vessel, so they should align with one common central axis. Their visible width may change with viewpoint, but their placement must remain structurally connected. A random tilt, a straight line instead of an ellipse, or unrelated widths breaks the vessel’s perspective and form. Thus option A is correct.

Correct answer: B. Compare distances on both sides of the central axis

Explanation: Symmetry means that corresponding points on the left and right sides occupy equal distances from a central axis. Lightly draw or imagine the bottle’s vertical centre line, then compare the neck, shoulders, body, and base on both sides. Darkening the contour or filling shadows may improve appearance but cannot prove accurate structure. Blending the bottle with the background is irrelevant, so option B is correct.
