CAT4 Practice Pack — Grade 4

Answer Key — CAT4 Grade 4

1. 1. D — In the top row, the figure shrinks and a smaller copy appears inside. Applying the same change to the bottom figure gives D. The others each make a specific mistake: A applies a different rule than the top row shows; B applies only one of the two changes; C right change, wrong figure shape; E the bottom figure with no rule applied.
2. 2. B — Lay one design over the other: every mark from both appears once. That gives B. The others: A invents a mark neither design has; C loses one mark in the merge; D the merged design slid one place; E keeps only the first design.
3. 3. D — The relationship is "tool to what it does." broom → sweep, so needle → sew.
4. 4. A — The pattern subtracts 5 each time. 16 − 5 = 11.
5. 5. A — In the top row, the figure doubles and the figure shrinks. Applying the same change to the bottom figure gives A. The others each make a specific mistake: B applies a different rule than the top row shows; C the bottom figure with no rule applied; D copies the top row's result instead of transforming the bottom figure; E applies only one of the two changes.
6. 6. E — Lay one design over the other: every mark from both appears once, and a mark both designs share appears once, not twice. That gives E. The others: A keeps only the marks the designs share; B the merged design slid one place; C keeps only the second design; D keeps only the first design.
7. 7. C — The relationship is "animal to its home." dog → kennel, so cow → barn.
8. 8. D — The pattern subtracts 5 each time. 23 − 5 = 18.
9. 9. A — In the top row, the figure shrinks and the figure grows. 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 only one of the two changes; D a look-alike that doesn't follow the rule; E applies a different rule than the top row shows.
10. 10. A — Lay one design over the other: every mark from both appears once, and a mark both designs share appears once, not twice. That gives A. The others: B keeps only the first design; C loses one mark in the merge; D keeps only the marks the designs share; E invents a mark neither design has.
11. 11. D — The relationship is "what it grows or turns into." cub → bear, so puppy → dog.
12. 12. D — The pattern subtracts 6 each time. 31 − 6 = 25.
13. 13. B — In the top row, the figure grows and the figure shrinks. Applying the same change to the bottom figure gives B. The others each make a specific mistake: A copies the top row's result instead of transforming the bottom figure; C a look-alike that doesn't follow the rule; D applies only one of the two changes; 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, and a mark both designs share appears once, not twice. That gives C. The others: A the merged design slid one place; B loses one mark in the merge; D keeps only the second design; E invents a mark neither design has.
15. 15. D — The relationship is "tool to what it does." hammer → hit, so spoon → eat.
16. 16. C — The pattern subtracts 4 each time. 31 − 4 = 27.
17. 17. C — In the top row, the figure grows and the figure doubles. Applying the same change to the bottom figure gives C. The others each make a specific mistake: A copies the top row's result instead of transforming the bottom figure; B the bottom figure with no rule applied; D applies only one of the two changes; E applies a different rule than the top row shows.
18. 18. C — Lay one design over the other: every mark from both appears once. That gives C. The others: A keeps only the first design; B keeps only the second design; D invents a mark neither design has; E the merged design slid one place.
19. 19. D — The relationship is "animal to its home." horse → stable, so ant → colony.
20. 20. A — The pattern subtracts 2 each time. 42 − 2 = 40.
