Rule: the square's number of copies increases by a constant step of 1 unit(s) per panel (count-scale index). Panel 1 = 3 copies, panel 2 = 4 copies, panel 3 = 5 copies. Adding the same step once more gives the missing panel: 6 copies — this is option A. Option B applies a step of 2 unit(s) instead of 1, over- or under-shooting the established rate of change. Option C shows the same number of copies as panel 2, reversing the progression instead of continuing it forward. Option D has the correct number of copies value but substitutes a parallelogram for the square, breaking the requirement that the same shape appear in every panel.

2The 3x3 grid below follows two independent rules: every cell in a given row uses the same shape, and every cell in a given column uses the same size. Study the pattern across the completed rows and columns, then choose the option that correctly completes the missing bottom-right cell.

Answer: <svg xmlns="http://www.w3.org/2000/svg" width="150" height="232" viewBox="0 0 150 232"><rect x="0" y="0" width="150" height="232" fill="#ffffff"/><rect x="1" y="1" width="148" height="188" fill="#ffffff" stroke="#111827" stroke-width="2"/><polygon points="94.0,76.0 94.0,114.0 56.0,114.0 56.0,76.0" fill="#6b7280" stroke="#111827" stroke-width="2"/><rect x="0" y="188.0" width="150" height="44" fill="#111827"/><text x="75.0" y="219.0" font-size="22" font-weight="bold" font-family="Arial, sans-serif" text-anchor="middle" fill="#ffffff">C</text></svg>
Rule: each row is assigned a fixed shape (hexagon for row 1, parallelogram for row 2, square for row 3) that stays constant across all three columns, and each column is assigned a fixed size (small for column 1, medium for column 2, large for column 3) that stays constant across all three rows. The missing cell is row 3, column 3, so it must combine row 3's shape (square) with column 3's size (large) — this is option C. Option A uses the correct row-3 shape (square) but the wrong column size (medium instead of large), violating the column rule. Option D uses the correct column-3 size (large) but the wrong shape (parallelogram instead of square), violating the row rule. Option B uses the correct size but substitutes a diamond, a shape that does not appear anywhere in the grid, violating the row rule entirely.

3Each panel below shows one circle. Moving from panel 1 to panel 3, the circle's number of copies changes by the same fixed amount at every step. Study the pattern, then choose the option that correctly completes the missing 4th panel.

4Each panel below shows one square. Moving from panel 1 to panel 3, the square's shading (darkness) changes by the same fixed amount at every step. Study the pattern, then choose the option that correctly completes the missing 4th panel.

Rule: the square's shading (darkness) increases by a constant step of 1 unit(s) per panel (shading-scale index). Panel 1 = shading level 2 of 6 (darker = higher), panel 2 = shading level 3 of 6 (darker = higher), panel 3 = shading level 4 of 6 (darker = higher). Adding the same step once more gives the missing panel: shading level 5 of 6 (darker = higher) — this is option B. Option D applies a step of 2 unit(s) instead of 1, over- or under-shooting the established rate of change. Option A shows the same shading (darkness) as panel 2, reversing the progression instead of continuing it forward. Option C has the correct shading (darkness) value but substitutes a triangle for the square, breaking the requirement that the same shape appear in every panel.

Rule: the pentagon's number of copies increases by a constant step of 1 unit(s) per panel (count-scale index). Panel 1 = 1 copies, panel 2 = 2 copies, panel 3 = 3 copies. Adding the same step once more gives the missing panel: 4 copies — this is option C. Option A applies a step of 2 unit(s) instead of 1, over- or under-shooting the established rate of change. Option D shows the same number of copies as panel 2, reversing the progression instead of continuing it forward. Option B has the correct number of copies value but substitutes a circle for the pentagon, breaking the requirement that the same shape appear in every panel.

10The 3x3 grid below follows two independent rules: every cell in a given row uses the same shape, and every cell in a given column uses the same size. Study the pattern across the completed rows and columns, then choose the option that correctly completes the missing bottom-right cell.

Rule: each row is assigned a fixed shape (parallelogram for row 1, circle for row 2, hexagon for row 3) that stays constant across all three columns, and each column is assigned a fixed size (small for column 1, medium for column 2, large for column 3) that stays constant across all three rows. The missing cell is row 3, column 3, so it must combine row 3's shape (hexagon) with column 3's size (large) — this is option D. Option C uses the correct row-3 shape (hexagon) but the wrong column size (medium instead of large), violating the column rule. Option B uses the correct column-3 size (large) but the wrong shape (circle instead of hexagon), violating the row rule. Option A uses the correct size but substitutes a triangle, a shape that does not appear anywhere in the grid, violating the row rule entirely.
