Find the glyph whose typographic features (serifs, stroke contrast, terminals, curvature) don't match the rest. Inspect each digit at normal and zoomed-in scale to identify which one has different terminal or stroke constructions.

Count distinct continuous surfaces produced when the planar region is swept around the given axis. The 270° sweep creates 10 surfaces total: 7 outer, 1 inner tube from the hole, and 2 radial end-surfaces.

Each fold flips the paper. Start from the blue pawn panel (FRONT), then walk along the strip panel-by-panel. Every time you cross a fold, flip the current side (FRONT↔BACK). Mark the side when you reach each red pawn.

Valid pairs require identical design with mirrored orientation (one left, one right). Identify distinct designs by color and strap pattern, then count only sets with both orientations present.

Horizontal translation does not affect area. Treat the figure as an isosceles triangle with 8 cm height. Calculate the area of the rightmost 4 cm strip using similar triangles or integration. The shifting of middle segments is irrelevant.

Count sphere-sphere contacts layer by layer. Four layers: 16 (4×4), 9 (3×3), 4 (2×2), 1 sphere. Calculate horizontal contacts within each layer, then vertical contacts between stacked layers. Avoid double-counting.

Count only distinct planes. Curved portions are single continuous surfaces. Break objects into primitives: cylinders (circle + strip), hexagons (top + sides), body sections. Object 1 = 15 faces, Object 2 = 15 faces.

Count all characters including spaces in fixed-width font. 10 words x 6 chars = 60 characters, plus 9 spaces between words = 69 total. Multiply by 0.6 cm = 41.4 cm.

Cylinder (R): Has a curved surface → can form circles, ellipses (curved shapes). Vertical cuts → rectangles or even squares. Cube (Q) & Hexagonal Prism (P): Flat faces → only polygons. Can form rectangles, squares, and isosceles triangles from angled cuts. Only hexagonal prism (P) can produce a regular hexagon when cut parallel to its base.

Match the orthographic constraints. Top view fixes the plan shape, front view fixes the height profile. A valid 3D object must simultaneously satisfy both views.

Read the graph and interpret rises and drops in the protagonist's fortune. Positive slope = improvement. Negative slope = setback. Flat = neutral or uneventful interval. A sharp fall around minutes 12–18 indicates a major setback. The rise toward the end indicates recovery and likely final success.

Cube folding preserves adjacency and orientation through rotation only. No face can flip or mirror. Identify the central face and its four neighbors in the net. Track which edge each neighbor attaches to. Mentally rotate each neighbor 90° around its shared edge.

A mechanism moves only if each link has at least one degree of freedom through hinges and the overall structure avoids forming a rigid loop. Hinges must create open kinematic chains, not closed locked polygons.

This question tests understanding of design-for-manufacture (DFM) and design-for-assembly (DFA) principles. Students must infer from each chair's shape and material whether it: (1) Stacks easily (single-piece form, tapered legs, no protrusions), or (2) Requires many manufacturing/assembly operations (many components, joints, welds, fasteners, different materials).

This question tests whether students can identify ergonomic design features and mechanical functions of different scissors. Key aspects: (1) Handedness based on blade orientation and handle shape, (2) Spring-loaded vs manual operation, (3) Symmetrical vs ergonomic handles for ambidextrous usability, (4) Effort required depending on mechanical assistance.

Understanding perspective drawing requires knowledge of vanishing points, horizon lines, and how parallel lines converge. In one-point perspective, all parallel lines converge to a single vanishing point on the horizon line.

Bauhaus emphasized 'form follows function', integration of art and technology, and mass production. Key principles include simplicity, functionality, and the marriage of fine arts with crafts and industrial design.

Design thinking follows a human-centered approach with stages: Empathize, Define, Ideate, Prototype, and Test. Each stage has specific goals and methods for problem-solving.

Color theory involves understanding primary, secondary, and tertiary colors, color harmonies (complementary, analogous, triadic), and color properties (hue, saturation, brightness).

Typography involves understanding typeface anatomy, hierarchy, readability, and the relationship between text and layout. Key concepts include kerning, leading, tracking, and font classification.

Gestalt principles explain how humans perceive visual elements as unified wholes. Key principles include proximity, similarity, closure, continuity, and figure-ground relationship.

Understanding material properties involves knowing mechanical properties (strength, elasticity, hardness), thermal properties (conductivity, expansion), and aesthetic properties (texture, color, finish).

Ergonomics focuses on designing products that fit human capabilities and limitations. Key considerations include anthropometric data, biomechanics, and cognitive factors.

Sustainable design considers the entire product lifecycle, from material extraction to disposal. Key principles include reducing waste, using renewable materials, and designing for durability and recyclability.

Visual hierarchy guides the viewer's eye through a design using size, color, contrast, positioning, and typography. It establishes the order of importance for different elements.

UX design focuses on creating meaningful and relevant experiences for users. It involves user research, information architecture, interaction design, and usability testing.

Design history encompasses various movements like Art Nouveau, Bauhaus, Modernism, and Postmodernism. Each movement had distinct characteristics, philosophies, and influential figures.

This is a spatial pattern puzzle where you need to identify which hexagon fits based on the arrangement and types of shapes (triangles and circles, filled or unfilled) in the connected hexagons.

Understanding how parallel light rays create shadows of 3D objects. When sunlight hits at 45° angle: a horizontal circular disc creates an elliptical shadow (stretched oval), while a sphere always creates a circular shadow regardless of light angle.

Identifying the correct 2D profile (side view/silhouette) of a 3D arrangement. Profile = side view silhouette (usually from right side), showing outline when viewed from 90° to original view. All visible elements merge into one flat shadow/outline.

Understanding horizontal mirror reflection where text appears reversed as if seen in a mirror placed vertically. Letters flip horizontally (left ↔ right), letter order reverses in each word, but spacing and vertical alignment stay unchanged.

Identifying Indian classical dance forms based on their distinctive visual characteristics like costumes, postures, ornaments, and regional styles. Key forms: Bharatanatyam (Tamil Nadu, angular poses), Kathak (North India, spinning), Kathakali (Kerala, elaborate makeup), Odissi (Odisha, tribhanga pose), Mohiniyattam (Kerala, graceful feminine), Manipuri (drum-shaped skirt), Kuchipudi (Andhra Pradesh, brass plate dance).

Understanding spatial transformation when a transparent sheet with a printed image is folded along a specific line. Since the sheet is transparent, you see BOTH the original image underneath AND the folded portion on top (mirrored), creating an overlapping/superimposed effect.

Understanding motion continuity in animation by identifying the missing frame that creates smooth, logical movement progression. The sequence shows: picking up sack → holding low → lifting → [MISSING: sack at shoulder level] → overhead position. Missing frame bridges 'lifting from waist' to 'overhead'.

This question requires analyzing design elements and their relationships within a composition.

Understanding color inversion where specific colors are swapped: blue sky becomes black, green leaves become white, white birds become black. This creates a selective negative effect with inverted colors.

The 180-degree rule maintains spatial continuity in film by keeping the camera on one side of an imaginary line between characters. This ensures consistent screen direction and eye-lines. Camera must stay on ONE side of the line connecting two people in conversation.

Visualizing the top view of a 3D bent wire by understanding how depth disappears when viewed from above. Top view = looking straight down. All vertical elements collapse into points/lines. Only horizontal (X-Y plane) movements are visible.

Finding symbol-to-number assignments where same symbols represent same values across all equations. Solve systematically: T² = S, S + T = X, T × C = X, X + C = 25. Solution: T = 4, S = 16, C = 5, X = 20.

Visualizing the result when paper is folded along lines and cut, then unfolded to reveal a symmetrical pattern. Paper folded accordion-style (7-8 vertical folds), cuts made on top and bottom edges create V-shaped notches. Each cut goes through ALL layers, creating diamond/rhombus shapes when unfolded.
