Proportion

Correct answer: C. The human figure will appear unnatural

Explanation: A head that is much larger than the body creates an incorrect part-to-whole size relationship. Unless the artist intentionally uses caricature, the figure will therefore look unbalanced or unnatural. Option C is correct. Colour beauty, the speed of rhythm, and the amount of texture are separate visual concerns; changing the head-to-body size relationship does not automatically produce any of those effects.

Correct answer: D. When their sizes suit the whole form of the object

Explanation: Parts are correctly proportioned when their sizes and measurements relate suitably to the complete form of the object. The parts do not need to be equal; they need to be appropriate to their function and position within the whole. Option D is correct. One colour concerns colour choice, maximum size is irrelevant, and making every part equal would often produce an unrealistic object rather than a proportionate one.

Correct answer: C. To the other facial features

Explanation: The governing concept is proportion within a whole form. In a portrait, the mouth must be sized in relation to the eyes, nose, jaw, and overall width of the face. This part-to-part and part-to-whole comparison makes the drawing believable, so option C is correct. Hair colour, background size, and paper width do not determine the natural size of the mouth; they are unrelated to facial proportion.

Correct answer: D. Natural proportion will appear incorrect

Explanation: The governing concept is natural proportion, which requires related parts of an object to have believable sizes. A tree trunk supports the branches, so making it extremely thin compared with them creates a structural and visual mismatch. Option D is correct because the drawing will not agree with the observed form of a tree. Colour harmony, rhythm, and increased realism do not result from an incorrect trunk-to-branch relationship.

Correct answer: A. Believability

Explanation: The governing concept is proportion: related objects and parts are shown in suitable size relationships. When these relationships agree with observation or the intended design, the viewer can accept the picture as believable and visually convincing. Therefore, option A is correct. Brightness, roughness, and decoration may be produced by colour, texture, or design treatment, but they are not the essential quality created by correct proportion.

Correct answer: B. The flower's proportion will appear inconsistent

Explanation: The governing concept is proportion between parts of a whole. A flower’s petals and centre should have a suitable size relationship based on the observed form or the intended design. If the petals are much too small, the centre dominates and the flower looks visually incorrect, so option B is correct. The mistake does not automatically reduce colour, alter only rhythm, or remove the texture of the petals.

Correct answer: C. Unnatural

Explanation: The governing concept is part-to-whole proportion. Every important part of an object should have a size that fits the complete form and supports its visual structure. If one part is too large or too small, the viewer notices a mismatch and the object appears unnatural; therefore, option C is correct. Such a mismatch does not automatically make the object brighter, balanced, or merely decorative, because those qualities involve other design features.

Correct answer: D. The stool will appear disproportionate and unsuitable for use

Explanation: The governing concept is functional proportion: the parts of a designed object must relate suitably to one another and to its use. If a stool’s legs are too short for its seat, its height becomes impractical and the object looks visually awkward. Option D is correct. Colour contrast, line rhythm, and texture describe other visual qualities; they do not explain the unsuitable seat-to-leg relationship or the loss of comfortable function.

Correct answer: A. Proportion

Explanation: The governing concept is proportion, defined in art as the size relationship among parts of an object or composition, and sometimes between a part and the whole. Option A is correct because it names this relationship directly. Rhythm concerns repeated visual movement, emphasis makes one area dominant, and contrast creates noticeable difference between elements. Those principles can work with proportion, but none is the definition asked for here.

Correct answer: B. The adult generally larger

Explanation: The governing concept is age-based proportion. In ordinary observation, an adult has a larger and taller body than a small child, although the exact appearance also depends on pose and distance. Thus option B is the suitable general relationship when both figures are shown under comparable conditions. Equal figures ignore the difference in age and body scale, while the child being always larger or the bodies being reversed contradicts normal observation.

Correct answer: C. Facial proportion and appearance

Explanation: The governing concept is proportion: each facial feature should have a suitable size relationship with the others. If the eyebrows are much thicker than the eyes, the balance of the face changes and the portrait may look unnatural or exaggerated. Therefore, facial proportion and overall appearance are affected. Colour harmony, texture, and rhythm do not directly describe this size relationship.

Correct answer: D. Unusually proportioned

Explanation: The governing concept is proportion, which compares the relative dimensions of parts or sides of an object. A cupboard that is extremely tall but very narrow has an unusual height-to-width relationship, so it may look awkward or unlike a normally designed cupboard. Thus, it is unusually proportioned. Colour, rhythm, and natural appearance do not explain the unusual dimensions.

Correct answer: C. The bicycle is disproportionate

Explanation: The governing concept is proportion, meaning the appropriate relationship among the sizes of connected parts. Bicycle wheels that are too large for the frame disturb the expected relationship between the wheels, frame, seat, and other components. The bicycle will therefore look disproportionate or unnatural. Balance, decoration, and colour contrast may occur separately, but they do not explain the incorrect size relationship.

Correct answer: D. The body proportion will change

Explanation: The governing concept is human-figure proportion. The legs and torso have a relative length relationship that helps make a figure look natural. If the legs are drawn excessively long, that relationship is altered, so the figure’s body proportion changes and may look distorted. Colour, texture, and rhythm are separate visual concerns and do not result directly from changing limb length.

Correct answer: A. Natural and organized

Explanation: The governing concept is proportion: the parts of an object should have suitable relationships in size and placement. When those relationships are appropriate, the object usually appears natural, coherent, and organized to the viewer. Therefore, option A is correct. Proper proportion does not require bright colour, perfect symmetry, or a large overall size; an object can be dull, asymmetrical, or small and still be well proportioned.

Correct answer: B. Natural proportion

Explanation: The governing concept is proportion in animal drawing. A rabbit’s ears must have a believable length in relation to its head and body for the animal to look natural. When that relationship is suitable, the drawing shows natural proportion. Rhythm, colour harmony, and texture may be added to an artwork, but none of them explains whether the ears have the correct size relative to the body.

Correct answer: C. Size and measurement

Explanation: In art, proportion mainly compares the relative size and measurement of parts within an object, figure, or composition. For example, an artist may compare the length of a person’s arm with the torso or the width of a wheel with a bicycle frame. Therefore, size and measurement is correct. Colour and texture describe surface qualities, line and direction describe marks, and light and shadow describe tone and depth.

Correct answer: D. Objects appear unnatural

Explanation: The governing concept is proportion, which controls the believable size relationships among parts of an object or scene. When those relationships are incorrect, objects may look distorted, awkward, or unnatural even if the colours and lines are attractive. Thus, option D is correct. Light colours, the presence of lines, or a different texture can occur in many successful pictures and are not reliable signs of incorrect proportion.

Correct answer: A. Correct object proportion

Explanation: The governing concept is proportion: it describes how the sizes of parts relate to one another and to the whole object. Here, the jug’s spout is suitably sized in relation to its body, so the object looks coherent and functional. Therefore, option A is correct. Colour rhythm concerns repeated colour, line contrast concerns differences between lines, and texture balance does not identify this size relationship.

Correct answer: C. An unnatural size relationship

Explanation: The governing concept is proportion in relation to real-world size. An elephant is ordinarily much larger than a dog, so drawing it smaller reverses the expected relationship and makes the image appear unnatural. Therefore, option C is correct. Natural proportion would preserve a believable size relationship; colour harmony concerns compatible colours, while line rhythm concerns repeated or flowing lines rather than the sizes of animals.

Correct answer: D. Error of functional proportion

Explanation: The governing concept is functional proportion: an object must have a suitable size for its surrounding space and intended use. A very small door would not fit the scale of the wall and room, and it might not be usable by a person. Therefore, option D is correct. Colour, rhythm, and texture describe other visual qualities; none explains why the door’s dimensions are unsuitable.

Correct answer: A. Visual balance

Explanation: The governing concept is proportion and its effect on composition. When small and large parts have suitable size relationships, the design feels organised, stable, and visually balanced rather than awkward or accidental. Therefore, option A is correct. Colour temperature concerns warm and cool colours, texture concerns surface quality, and line movement concerns the direction or flow of lines; these do not directly name the result of proper size relationships.

Correct answer: B. Compare the sizes of parts and the whole

Explanation: The governing concept is observational measurement for proportion. Before correcting a drawing, the artist should compare the sizes of individual parts with the whole and check their relationships. This reveals whether a feature is too large, too small, too long, or too short. Therefore, option B is correct. Applying colour, erasing the background, or changing paper does not diagnose the size relationship that needs improvement.

Correct answer: C. To the whole face and other features

Explanation: The governing concept is facial proportion. The chin is one part of a complete face, so its width, length, and position must relate to the forehead, nose, mouth, jaw, and overall facial structure. Therefore, option C is correct. Matching the chin only to the hair or neck ignores the complete arrangement, while the background does not determine the relative size of facial features.

Correct answer: D. The foot's proportion will appear incorrect

Explanation: The governing concept is proportional consistency within a body part. The toes must have a believable length in relation to the entire foot; if they are excessively long, the relationship between the parts becomes distorted. Therefore, option D is correct. The foot would not become more realistic, and the change would not create colour harmony or rhythm because those concepts concern colour relationships and repetition, not anatomical size.
