Pencil drawing

Correct answer: A. जब वस्तु और पृष्ठभूमि के मान इतने समान हों कि सीमा विलीन लगे

Explanation: A lost edge occurs when the value, colour, or tone of an object approaches that of the adjacent background, causing the boundary to merge visually instead of remaining sharply outlined. Option A states this condition precisely. Lost edges can make forms recede and help direct attention toward sharper found edges. A thick outline usually creates a hard edge, while eraser use or horizontal lines does not define the concept.

Correct answer: B. चिकनी परावर्तक सतह आसपास के दृश्यों को तीखे रूप में दर्शाती है

Explanation: Shiny metal has a smooth, highly reflective surface, so it reflects the surrounding light sources, dark areas, and nearby objects rather than showing one even local value. Small changes in the reflected environment can therefore produce sharp bands or abrupt transitions between light and dark. Option B is correct. Metal still has volume, pencil limitations do not cause the pattern, and a vessel need not have flat surfaces to show strong reflections.

Correct answer: C. निचली दीर्घवृत्ताकार सतह

Explanation: In perspective drawing, the visible part of a cylindrical object depends on the observer’s eye level. When the cylinder is above that level, the viewer is looking upward at it and can see its underside, which is represented as a lower elliptical surface. Thus option C is correct. The top surface would be expected when the cylinder is below eye level; a centre line is not a surface, and the object does not hide all of its surfaces.

Correct answer: C. Some selected lines can support structure, movement and the artist's process

Explanation: The governing concept is that construction lines are guides for proportion, gesture and form. After the drawing is developed, confusing or unnecessary marks should be lightened or erased, but a few controlled lines may clarify structure, movement or the artist’s working process. Therefore option C is correct; darkness, paper colour and pencil protection do not explain their artistic function.

Correct answer: D. A combined check of structure, proportion, perspective, values, edges, materials and focal point

Explanation: A balanced final review follows the governing principle that a drawing succeeds through coordinated visual decisions, not through one impressive feature. The artist should inspect structure and proportion, perspective, light-dark values, edge control, material description and the focal point, both as separate parts and as a whole. Option D is correct; darkness, texture count or pencil-grade variety alone cannot judge the complete drawing.

Correct answer: A. First overall composition, then proportion, then tone, and finally detail

Explanation: The governing principle of drawing critique is to move from large structural features to small surface details. First inspect composition and placement, then proportion and perspective, next light-dark tone and value balance, and finally texture and detail. Option A is correct because it prevents minor details from hiding major errors. Options B, C, and D are incomplete because they ignore essential relationships in the whole drawing.

Correct answer: C. Technique should serve the intended form, material, atmosphere, and focal point

Explanation: The governing principle is purposeful technique: materials and marks should communicate the subject rather than compete with it. An expert artist selects pressure, line, hatching, blending, edges, and pencil hardness according to the intended form, material, atmosphere, and focal point. Showing every method would create distraction, and using only the softest pencil would limit control. Technical skill is successful when it supports visual meaning.

Correct answer: A. It lifts graphite selectively and disturbs the surface less

Explanation: The governing concept is subtractive drawing: highlights can be created by removing selected graphite rather than adding white pigment. A kneaded eraser can be shaped to a small point, pressed onto a chosen area, and lifted to remove a controlled amount of graphite. Option A is correct because this preserves soft edges and paper texture; rubbing may smear graphite or damage the surface.
