Proportion

Correct answer: C. A child's head is relatively larger compared with the body

Explanation: Figure proportion changes with age. A child’s head occupies a larger fraction of total body height, while an adult’s body is taller in relation to the head and the limbs are more developed. Therefore option C is correct. The difference is relative, not an absolute claim that every child has the same measurements. Adult heads are not proportionally larger, and the statement about children’s legs is clearly exaggerated.

Correct answer: D. The form will appear unnatural

Explanation: In sculpture, proportion governs the size relationships among three-dimensional parts, such as the head, torso, arms, and legs. If one part is too large or too small in relation to the others, the complete figure loses anatomical or visual credibility and appears unnatural. Thus option D is correct. Drying time, weight, and surface shine depend mainly on materials, thickness, finishing, and treatment, not on proportional accuracy.

Correct answer: A. Relationship between main height and width

Explanation: Proportion means the relationship between the sizes of parts and the whole. An artist should first compare the main height with the main width because these broad measurements establish the form’s basic structure. If this relationship is wrong, details and colour cannot correct the drawing. Colour intensity, paper thickness, and the title do not determine the object’s size relationships, so option A is correct.

Correct answer: B. Other objects and the whole composition

Explanation: In art, proportion describes how the size of one part relates to other parts and to the complete composition. A small object should therefore look believable beside nearby objects and within the overall design. The frame, light source, or direction of a line may affect presentation, but none alone establishes proportional size. Thus option B gives the complete relationship.

Correct answer: C. To show visual importance and priority

Explanation: Proportion is not only about realistic objects; it also controls relative visual importance in a design. Making a poster title larger gives it greater visual weight, establishes hierarchy, and helps the viewer notice the message first. It does not hide the image, make every element equal, or increase texture. The intended reason is therefore visual priority, making option C correct.

Correct answer: D. The proportion of parts is incorrect

Explanation: A cup is understood through the size relationship between its bowl, rim, base, and handle. If the handle is drawn much larger than the main body without a special design reason, the parts no longer appear naturally related. This is a proportional error, not a problem of colour, line strength, or texture. Therefore option D correctly identifies the conclusion.

Correct answer: A. By enlarging all parts in the same ratio

Explanation: Uniform enlargement preserves proportion. If the original length, width, stalk, outline, and vein spacing are all multiplied by the same scale factor, their relationships remain unchanged while the whole leaf becomes larger. Enlarging only the stalk, removing veins, or changing width without length distorts the specimen. Thus option A describes the correct scientific drawing method.

Correct answer: B. With the distance between eye line and chin

Explanation: Facial proportion is judged by comparing one feature with stable reference points on the same face. The distance from the eye line to the chin provides a useful vertical guide for placing and sizing the nose. Hair colour, ear texture, and background width do not measure facial length. Therefore option B supplies the relevant proportional comparison.

Correct answer: D. Difference in importance will be unclear

Explanation: Relative size helps establish visual hierarchy: larger or more prominent elements can signal greater importance, while smaller elements can support them. If every element has exactly the same size, the viewer receives fewer proportional cues about priority, and the composition may feel flat or confusing. This does not automatically change light, texture, or colour balance, so option D is correct.

Correct answer: A. They help compare placement and measurements

Explanation: Construction guidelines provide common horizontal and vertical references. They help an artist compare the height, width, alignment, position, and spacing of different parts before darker details are added. Because the lines are guides rather than colour, paper reinforcement, or texture-making tools, option A is the only correct answer. Light guidelines make proportional correction easier.

Correct answer: C. Relation of parts according to an accepted ideal form

Explanation: Ideal proportion means arranging the parts of a figure or object according to a culturally or artistically accepted ideal of beauty and form. It does not require every part to be equal or to copy nature exactly. Therefore, option C is correct because it describes the intended relationship among parts, while A ignores variation, B refers only to literal measurement, and D rejects proportion altogether.

Correct answer: A. The composition looks natural and organised

Explanation: Good proportion creates believable relationships among the sizes of objects and their parts. When these relationships work together, the composition appears natural, coherent, and organised. Option A is correct because it describes the visual unity produced by suitable proportions. Colour darkness, automatically straight lines, and loss of texture are separate issues and do not follow from proportion.

Correct answer: B. Selective exaggeration

Explanation: When an artist intentionally enlarges just one feature, the change is called selective exaggeration. It breaks ordinary proportional relationships to draw attention to that feature or to communicate expression. Option B is correct. Proportional enlargement would increase parts consistently, symmetry concerns matching sides, and colour harmony concerns relationships among colours rather than figure size.

Correct answer: C. Structural proportion will look weak

Explanation: A tree trunk and its branches must have a visually believable size relationship. If the trunk is extremely thin beside heavy branches, it appears unable to support them, so the drawing loses structural credibility. Option C is correct because the proportional relationship is weak. The change does not automatically improve realism, colour balance, or background darkness.

Correct answer: D. Facial proportion

Explanation: Facial features are judged in relation to one another. The ears must have suitable size and placement compared with the eyes, nose, mouth, jaw, and overall head shape. Option D is correct because these relationships are part of facial proportion. Colour, texture, and shadow may affect appearance, but none alone determines the ears’ proper size and position.

Correct answer: A. Original proportion is preserved

Explanation: The grid method divides the original drawing and the larger surface into corresponding squares. The artist copies the contents of each small square into its matching larger square, keeping positions and relationships consistent. Thus option A is correct: the original proportion is preserved during enlargement. The method does not fill colour automatically, add texture, or prevent erasing.

Correct answer: B. The form will look elongated and distorted

Explanation: Proportion depends on the relationship between dimensions such as length and width. If length increases but width stays fixed, the ratio changes; for example, a form that was 2:1 may become 3:1. It will therefore look stretched or distorted. Option B is correct, while colour and texture are unrelated, and the original proportion cannot remain unchanged.

Correct answer: C. Cultural ideal proportion

Explanation: An idealised body is deliberately shaped according to a culture’s beliefs about beauty, strength, divinity, or human perfection. Artists may lengthen, simplify, or regularise features rather than copy an individual exactly. Option C is correct because it identifies cultural ideal proportion. Such forms are not accidental errors, colour-only experiments, or unplanned compositions.

Correct answer: A. It reduces familiarity and reveals size relationships

Explanation: The governing concept is proportional observation: a drawing must be judged by relationships among shapes, lengths, and positions. Turning it upside down makes the subject less familiar, so the artist notices angles, gaps, and size differences instead of mentally correcting them as a known object. Therefore option A is correct; changing colours, enlarging paper, or removing shadows does not result from inversion.

Correct answer: B. Modular proportion

Explanation: The governing concept is modular proportion. In this method, one selected part becomes a repeated measuring unit, and other dimensions are compared with it. For example, an artist may use the head length to estimate the height and divisions of a figure. Thus option B is correct; colour schemes concern colour relationships, texture concerns surface quality, and free drawing does not require a fixed unit.

Correct answer: C. Visual hierarchy

Explanation: The governing concept is proportion used to create visual hierarchy. When the main subject is made larger and supporting elements are made smaller, viewers usually recognise the intended order of attention. The size relationships guide the eye through the composition. Therefore option C is correct; surface, outline, and paper quality may be affected by other choices, but not directly by planned size contrast.

Correct answer: D. Short and disproportionate

Explanation: The governing concept is bodily proportion, which compares the lengths and positions of related sections within the whole figure. If the legs are made much shorter while the torso and head remain unchanged, the total height and body divisions no longer match a convincing structure. Therefore option D is correct. The change does not make the figure more realistic, balanced, or farther away; it creates a shortened, disproportionate appearance.

Correct answer: A. Changing viewpoint can alter apparent measurements

Explanation: The governing concept is consistent visual measurement. Moving the head or body changes the viewing angle, alignment, and apparent relative size of parts, especially when the subject has depth. With a fixed viewpoint, comparisons are made from the same visual conditions, so errors are easier to detect. Therefore option A is correct; movement does not itself dry colours, thicken lines, or bend the paper.

Correct answer: B. Believable relationship between parts and the whole

Explanation: The governing concept of proportion is the believable relationship between individual parts and the complete form. A successful drawing makes the size, placement, and division of its elements appear coherent when viewed together. Therefore option B is correct. Using one colour, keeping every line equally thick, or adding a bright background may be stylistic decisions, but none proves that the form is proportionally sound.

Correct answer: B. Relative proportion compares different objects while internal proportion compares parts within one form

Explanation: The governing concept is proportion, meaning the relationship of sizes. Relative proportion compares one object with another, such as a person with a building or a head with a whole figure. Internal proportion examines how parts within one form relate, such as the fingers to the palm. Therefore, option B states the distinction accurately; the other choices confuse proportion with colour or distance, or deny comparison.
