Triangle, Square, Pentagon, and Hexagon are all polygons (have straight sides and vertices). Circle is the only curved shape without straight sides.
Woman → Son's mother = Woman. Woman's father = Boy's grandfather. Grandfather's only daughter = Woman. This is logically consistent - she is indeed her son's mother and her father's only daughter.
The constraints 'Box 3 between 2&4' and 'Box 5 right of Box 4' and 'Box 8 left of Box 1' create conflicting arrangements in a linear sequence. Box 8 cannot be immediately left of Box 1 in a line where boxes are numbered sequentially.
LAMP produces LIGHT. THERMOMETER measures TEMPERATURE. Relationship is object-to-purpose.
This is the Fibonacci sequence where each number is sum of previous two. 8+13=21. Then 13+21=34.
Red < Blue. Yellow < Green. Red < Black < Green. Testing: Yellow(1), Red(2), Black(3), Green(4), Blue(5). Check: Red<Blue✓, Yellow<Green✓, Red<Black<Green✓. This satisfies all conditions.
D=4, E=5, A=1, R=18 (position from end of alphabet: D=23→4, E=22→5, A=26→1, R=9→18). For CARE: C=3, A=1, R=18, E=5 = 3-1-18-5.
Differences: 4, 6, 8, 10, 12, 14, 16. Pattern increases by 2 each time. 42 + 14 = 56. Next would be 56 + 16 = 72.
If P is 8th from left in a row of 12, then from right: 12 - 8 + 1 = 5. P is 5th from the right.
BOOK is the object used to READ. KEYBOARD is the object used to TYPE. The relationship is object-to-action.
