CAT4 Practice Pack — Grade 6

Answer Key — CAT4 Grade 6

1. 1. B — In the top row, a smaller copy appears inside and the figure shrinks. Applying the same change to the bottom figure gives B. The others each make a specific mistake: A applies only one of the two changes; C the bottom figure with no rule applied; D applies a different rule than the top row shows; E copies the top row's result instead of transforming the bottom figure.
2. 2. E — Lay one design over the other: every mark from both appears once. That gives E. The others: A keeps only the second design; B the merged design slid one place; C keeps only the first design; D loses one mark in the merge.
3. 3. D — The relationship is "worker to their workplace." baker → bakery, so doctor → hospital.
4. 4. C — These are square numbers: 1², 2², … Next is 5² = 25.
5. 5. B — In the top row, the figure grows and a smaller copy appears inside. Applying the same change to the bottom figure gives B. The others each make a specific mistake: A applies only one of the two changes; C right change, wrong figure shape; D the bottom figure with no rule applied; E applies a different rule than the top row shows.
6. 6. B — Lay one design over the other: every mark from both appears once, and a mark both designs share appears once, not twice. That gives B. The others: A the merged design slid one place; C loses one mark in the merge; D keeps only the first design; E invents a mark neither design has.
7. 7. A — The relationship is "part to its whole." string → guitar, so wheel → car.
8. 8. C — The amount added grows by 1 each step. Adding 4 to 10 gives 14.
9. 9. E — In the top row, the figure grows and the figure doubles. Applying the same change to the bottom figure gives E. The others each make a specific mistake: A applies a different rule than the top row shows; B right change, wrong figure shape; C applies only one of the two changes; D the bottom figure with no rule applied.
10. 10. E — Lay one design over the other: every mark from both appears once. That gives E. The others: A invents a mark neither design has; B keeps only the second design; C the merged design slid one place; D loses one mark in the merge.
11. 11. A — The relationship is "what it grows or turns into." egg → chick, so acorn → oak.
12. 12. D — Each number is multiplied by 3. 81 × 3 = 243.
13. 13. C — In the top row, the figure grows and a smaller copy appears inside. Applying the same change to the bottom figure gives C. The others each make a specific mistake: A the bottom figure with no rule applied; B applies only one of the two changes; D copies the top row's result instead of transforming the bottom figure; E applies a different rule than the top row shows.
14. 14. C — Lay one design over the other: every mark from both appears once. That gives C. The others: A loses one mark in the merge; B keeps only the second design; D invents a mark neither design has; E keeps only the first design.
15. 15. A — The relationship is "what it grows or turns into." bud → flower, so egg → chick.
16. 16. B — The amount added grows by 1 each step. Adding 6 to 15 gives 21.
17. 17. A — In the top row, the figure doubles and the figure's fill darkens one step. Applying the same change to the bottom figure gives A. The others each make a specific mistake: B right change, wrong figure shape; C applies the change twice; D the bottom figure with no rule applied; E applies only one of the two changes.
18. 18. C — Lay one design over the other: every mark from both appears once, and a mark both designs share appears once, not twice. That gives C. The others: A keeps only the marks the designs share; B loses one mark in the merge; D keeps only the first design; E invents a mark neither design has.
19. 19. B — The relationship is "part to its whole." petal → flower, so wheel → car.
20. 20. D — The amount added grows by 1 each step. Adding 6 to 15 gives 21.
