Proportion

Correct answer: C. Error of spatial proportion

Explanation: The governing idea is spatial proportion, supported by visual perspective. When two similar people are placed at different distances, the farther person is normally represented with a smaller apparent size. Drawing the distant person as large as the nearby person ignores the relationship between depth and size, so option C is correct. Colour, rhythm, and texture do not determine the apparent size created by spatial placement.

Correct answer: D. Structural proportion will appear unbalanced

Explanation: Structural proportion requires supporting parts to look appropriate for the size and visual weight of the parts they carry. A heavy tabletop combined with very thin legs makes the table appear weak, unstable, or poorly designed, even if it could technically stand. Thus option D is correct. Colour attraction, rhythmic repetition, and texture are separate visual qualities and do not explain the mismatch between the top and its supports.

Correct answer: D. The functional proportion of the car will be doubtful

Explanation: Functional proportion connects visual size with practical use and believable construction. A car door must be large enough for a person to enter and leave, so drawing it even smaller than a wheel makes the vehicle’s design look unrealistic and functionally doubtful. Option D is therefore correct. The change does not by itself create colour harmony, rhythm, or greater dynamism; those ideas concern different principles of art.

Correct answer: B. To maintain correct overall proportion

Explanation: In figure drawing, the large forms establish the overall structure before smaller details are added. Comparing the head, torso, limbs, and total height first helps the artist maintain correct relationships and prevents details from being placed on an incorrectly sized framework. Thus option B is correct. Colour selection, texture, and line thickness may be considered later, but they do not explain the initial comparison of major forms.

Correct answer: C. The vertical proportion of the face is disturbed

Explanation: The governing concept is proportion, which means the size relationship among parts of a form. Even when the face has a suitable width, an excessively long chin increases the lower vertical section and changes the relationship between the forehead, nose, mouth, and chin. Thus the face looks vertically distorted. Colour, texture, and pictorial rhythm do not directly explain this structural change, so option C is correct.

Correct answer: D. Visually unstable

Explanation: The governing idea is proportion: the parts of an object should have suitable size relationships. A vase with a very small base and a very wide upper section has an uneven distribution of visual and physical support. The eye therefore reads it as likely to tip or as poorly designed, making it appear visually unstable. Colour and natural appearance do not determine this structural relationship, so option D is correct.

Correct answer: B. Gradually smaller as distance increases

Explanation: The governing concept is proportion in perspective. Although the trees are identical in actual size, their apparent size decreases as their distance from the viewer increases. The nearest tree should therefore be largest, with each farther tree drawn progressively smaller. This change in relative size communicates spatial depth. Drawing every tree equally large or making the farthest largest reverses the visual rule, so option B is correct.

Correct answer: C. Visual hierarchy and proportion

Explanation: The governing concepts are proportion and visual hierarchy. A poster normally gives the title greater size or visual prominence so viewers identify the main message first. If the title is tiny while supporting text is oversized, the relative scale of the text elements becomes inappropriate and the reading order becomes confusing. This affects both hierarchy and proportion, not merely colour, texture, or line rhythm. Thus option C is correct.

Correct answer: D. Exaggerated or stylized proportion

Explanation: The governing concept is proportion, specifically the relationship between the widths of body parts. Extremely broad shoulders combined with an unusually narrow waist depart from ordinary human measurements. The result may be intentional exaggeration, a heroic style, or another stylized treatment rather than a naturalistic figure. The change is not primarily colour contrast or rhythm, and it does not represent normal proportion. Therefore, option D is correct.

Correct answer: B. Because the relationship between function and size is incorrect

Explanation: The governing concept is functional proportion: each part should have a believable size in relation to the job it performs. Wings that are too small compared with the body do not convincingly suggest lift or support for flight, so the bird appears structurally unrealistic. Light colour, straight lines, or missing texture may affect style, but they do not explain the failure of the flight structure. Hence option B is correct.

Correct answer: A. To size relationships among parts of a building and the whole

Explanation: Architectural proportion is the relationship of size, length, width, and height among parts of a building and between those parts and the whole structure. Doors, windows, columns, and rooms should relate convincingly to one another. Therefore, option A is correct. Wall colour, decorative texture, and light direction may affect appearance, but they do not define proportion.

Correct answer: B. Believable relative proportion

Explanation: A correct elephant-to-person size relationship demonstrates relative proportion: objects are shown according to their believable size in relation to one another. Since an elephant is much larger than a person, a convincing drawing must preserve that relationship. Option B is correct. Colour harmony concerns colour combinations, rhythm concerns repetition, and texture concerns surface quality rather than size.

Correct answer: C. The structural proportion is unbelievable

Explanation: Proportion requires related parts to have believable sizes and functional relationships. Roots support and nourish the plant, so showing extremely tiny roots beneath a huge upper structure makes the plant appear structurally unrealistic. Option C is correct. Colour relationship, rhythm, and texture may be separate artistic concerns, but none explains the implausible size relationship between the roots and the upper part.

Correct answer: D. Inconsistent proportion and instability

Explanation: The container and its contents must have a believable size relationship. If many unusually large fruits are placed in a small container, the fruits may seem unable to fit, and the arrangement can appear visually unstable. Therefore, option D is correct. Colour contrast and texture variety concern appearance, while rhythm concerns repetition; neither directly explains the size mismatch.

Correct answer: A. Suitable size relationships support visual balance

Explanation: Proportion and balance are different principles, but they work together. When the sizes of forms are appropriate in relation to one another, their visual weight is easier to organize, helping the composition feel stable. Thus, option A is correct. Balance can also involve placement, colour, and emphasis, so it is not created only by colour; proportion does not always cause imbalance.

Correct answer: B. To compare the lengths of different parts

Explanation: In observational drawing, an artist can hold a pencil at arm's length, align it with a reference part, and use it as a simple measuring guide. The artist can then compare the lengths, widths, or angles of other parts with that reference. Option B is correct. Shading, mixing colour, and cutting paper are not the purpose of this proportional checking method.

Correct answer: C. Facial proportion related to placement and size

Explanation: Facial proportion includes both the size of features and their placement within the face. If the eyes are positioned too high, too low, too close, or too far apart, the portrait can look anatomically or visually incorrect even when the eyes themselves are well drawn. Option C is correct. Colour, texture, and background proportions do not specifically describe the placement of facial features.

Correct answer: D. Part-to-part proportion will be incorrect

Explanation: A human figure is judged by the relationships among connected parts, not by the length of one part alone. Even if the arms have suitable length, excessively large palms create an incorrect arm-to-palm relationship and may make the figure look distorted. Option D is correct. Rhythm and colour do not explain this anatomical size mismatch, and the figure cannot be fully correct when one part is disproportionate.

Correct answer: C. Internal proportion

Explanation: The governing concept is proportion, which compares the sizes of parts. Because the length and width are both measurements within the same face, their relationship is called internal proportion. It describes how the parts of one form fit together. Colour proportion concerns colour distribution, texture proportion is not the relevant standard term, and outer shape alone does not explain the dimensional comparison. Therefore, option C is correct.

Correct answer: D. The boat's functional and visual proportion will appear incorrect

Explanation: Proportion governs the relationship between the sizes of connected parts. A mast that is much too short compared with the boat changes the expected structural relationship, so the boat may look visually incorrect and less believable as a working vessel. Colour, rhythm, and texture do not explain this size mismatch. Thus, option D correctly identifies an error in functional and visual proportion.

Correct answer: A. To show depth and spatial proportion

Explanation: In visual art, relative size helps communicate space. If the front fruit is drawn larger and fruits behind it smaller, the viewer reads the difference as foreground and background, creating an impression of depth and spatial proportion. Making objects identical would weaken that spatial cue, while colour reduction and removal of texture address different artistic concerns. Therefore, option A is correct.

Correct answer: B. The effect of perspective and distance

Explanation: Perspective represents three-dimensional space on a flat surface. As identical windows are imagined farther from the viewer, their apparent size becomes smaller, even though their actual dimensions remain equal. This change is an example of apparent or spatial proportion produced by distance and viewpoint. Colour, texture, and line thickness may affect appearance, but they do not explain the size change here. Option B is correct.

Correct answer: C. Internal proportion

Explanation: Proportion compares measurable dimensions. The tree’s height and trunk thickness are two dimensions belonging to the same object, so their relationship is an internal proportion. Relative object proportion usually compares separate objects, spatial proportion concerns placement or distance, and colour proportion concerns the distribution of colours. Since the question compares parts of one tree, option C is the most precise answer.

Correct answer: D. Believable relative proportion

Explanation: Relative proportion communicates how large objects are compared with one another. If every object is drawn at the same size despite different real dimensions, the scene loses believable scale and the viewer cannot judge normal size relationships. Colour variety, texture, and rhythm may still be present, but they do not restore accurate size comparison. Therefore, option D correctly identifies the loss of believable relative proportion.

Correct answer: A. By making the main element larger than the other elements

Explanation: Proportion concerns the relative sizes of elements, while emphasis directs attention to a focal element. Making the main element larger than surrounding elements uses a deliberate size relationship to give it visual importance. Equal sizes usually reduce a clear size-based focal point; uniform colour and placing everything at the edge are not reliable explanations of this relationship. Therefore, option A is correct.
