OLSAT Practice Pack — Grade 2

Answer Key — OLSAT Grade 2

1. 1. A — In the top row, a smaller copy appears inside. 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 right change, wrong figure shape.
2. 2. D — In the top row, a smaller copy appears inside. Applying the same change to the bottom figure gives D. The others each make a specific mistake: A copies the top row's result instead of transforming the bottom figure; B applies a different rule than the top row shows; C the bottom figure with no rule applied; E right change, wrong figure shape.
3. 3. B — Each step, one more shape appears each time. Continuing one more step gives B. The others: A repeats the last figure instead of stepping on; C the right step on the wrong shape; D the right figure with the wrong fill; E steps backward in the series.
4. 4. D — The pattern subtracts 5 each time. 34 − 5 = 29.
5. 5. D — The relationship is "action to its opposite." ask → answer, so push → pull.
6. 6. A — mushroom, carrot, potato are all vegetables. Fishing is not, so it does not belong — answer A.
7. 7. B — bee goes with flower because the first one eats the second. In the same way monkey goes with banana — answer B. The other pictures do not go with monkey that way.
8. 8. C — In the top row, the figure's fill darkens one step. Applying the same change to the bottom figure gives C. The others each make a specific mistake: A applies a different rule than the top row shows; B the bottom figure with no rule applied; D copies the top row's result instead of transforming the bottom figure; E right change, wrong figure shape.
9. 9. B — In the top row, the figure's fill darkens one step. Applying the same change to the bottom figure gives B. The others each make a specific mistake: A applies a different rule than the top row shows; C copies the top row's result instead of transforming the bottom figure; D applies the change twice; E right change, wrong figure shape.
10. 10. E — Each step, the fill moves one step through the cycle (light to dark, then starting over). Continuing one more step gives E. The others: A repeats the last figure instead of stepping on; B the right step on the wrong shape; C steps backward in the series; D jumps two steps ahead.
11. 11. A — The pattern adds 4 each time. 16 + 4 = 20.
12. 12. D — The relationship is "animal to the sound it makes." dog → bark, so duck → quack.
13. 13. A — tree, evergreen, flower are all plants and trees. Sun is not, so it does not belong — answer A.
14. 14. E — sun goes with moon because the first one belongs to the day the way the second belongs to the night. In the same way rooster goes with owl — answer E. The other pictures do not go with rooster that way.
15. 15. B — In the top row, the figure grows. Applying the same change to the bottom figure gives B. The others each make a specific mistake: A 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 a look-alike that doesn't follow the rule.
16. 16. E — In the top row, the figure shrinks. Applying the same change to the bottom figure gives E. The others each make a specific mistake: A right change, wrong figure shape; B applies a different rule than the top row shows; C the bottom figure with no rule applied; D a look-alike that doesn't follow the rule.
17. 17. A — Each step, the fill moves one step through the cycle (light to dark, then starting over). Continuing one more step gives A. The others: B the right step on the wrong shape; C jumps two steps ahead; D repeats the last figure instead of stepping on; E the right figure with the wrong fill.
18. 18. A — These are square numbers: 2², 3², … Next is 6² = 36.
19. 19. B — The relationship is "opposites." high → low, so hard → soft.
20. 20. B — rabbit, hamster, dog are all animals people keep as pets. Banana is not, so it does not belong — answer B.
