Sketching

Correct answer: A. It gradually decreases

Explanation: Foreshortening represents a form that extends away from the viewer. As the cylindrical arm recedes, its visible width and apparent size gradually reduce because greater distance compresses the image. Therefore, option A is correct: the nearer end should look wider and the distant end narrower. Equal width weakens depth, an increase reverses the spatial effect, and sudden zero width would make the form look cut off rather than realistically receding.

Correct answer: A. The atmosphere reduces fine detail and contrast with distance

Explanation: Atmospheric perspective explains how air, dust, and moisture affect the appearance of distance. The greater the distance between the viewer and a mountain, the more intervening atmosphere softens tiny marks and reduces light-dark contrast. Thus option A is correct. The mountain still has real texture, so B is false; distant forms usually look lighter and less contrasted, not darker, and light does not fall only on the foreground.

Correct answer: A. The sense of depth will weaken

Explanation: A drawing shows depth through changes in edge quality as well as size and placement. Foreground objects generally have darker, sharper contours, while distant objects have softer and lighter edges because distance and atmosphere reduce clarity. If both edges are equally strong, the visual separation between planes is reduced, so option A is correct. A dark outline does not by itself make an object appear farther away.

Correct answer: A. Its purpose is to test composition and large value groups

Explanation: A thumbnail sketch is a small, rapid planning study. Its governing purpose is to compare composition, placement, proportion, and broad light–middle–dark value groups before committing to a finished drawing. Therefore option A is correct. A thumbnail is normally smaller, not larger, than the final work; proportion still matters, and texture is not its only or primary concern. Limited detail keeps the planning process fast and readable.

Correct answer: A. The main movement and energy of the body

Explanation: The governing concept is gesture construction. A line of action is a light, flowing guide that expresses the dominant direction, rhythm, balance, and energy of the whole pose. Thus option A is correct: the body is built around this movement line. Skin texture, clothing colour, and fine facial detail are later descriptive features; they do not explain the overall action or energy of the figure.

Correct answer: A. Stiff and less natural

Explanation: The governing concept is structural gesture and weight balance. In a natural standing or moving figure, the shoulders and pelvis often tilt or counterbalance one another as weight shifts. Drawing both axes parallel in every pose removes this opposition and can make the body look rigid and artificial. Therefore option A is correct. It does not automatically create greater movement, depth, or foreshortening, which require different visual evidence.

Correct answer: A. It is straighter and more stable beneath the body weight

Explanation: The governing concept is figure balance and the distribution of body weight. The weight-bearing leg carries the pelvis and torso toward the ground, so it is usually planted, more extended, and visually stable; the free leg is more relaxed or bent. Option A is correct. The supporting leg is not always in the air, is not physically shorter, and still has visible cylindrical volume and form.

Correct answer: A. To identify errors in spacing and placement

Explanation: The governing concept is negative-space observation. The empty shapes between and around objects have measurable angles, widths, and boundaries; comparing them helps the artist detect errors in spacing, alignment, overlap, and placement. Therefore option A is correct. Negative spaces are not merely decoration, they do not erase shadows, and they cannot determine a pencil colour. Treating empty areas as shapes improves accuracy in the whole group.
