Question 1 identifies the missing figure, revealing a green rectangle that is absent from a sequence of pictures. <br /><br />2. Question 2 involves finding a missing piece of a roof, with the red shape in choice B as the correct fit.<br /><br />3. For Question 3, spots on ladybugs are counted, totaling 19.<br /><br />4. Question 4 involves rotating an image, with choice E as the correct rotation.<br /><br />5. Question 5 describes the tower's component shapes as a cylinder and a cone.<br /><br />6. Question 6 adds numbers in a specific column to arrive at the sum of 10.<br /><br />7. Question 7 calculates the duration of a movie as 1 hour by doubling the time of half the movie.<br /><br />8. For Question 8, the shortest strip involves the largest overlap, determined to be strip B.<br /><br />9. In Question 9, the total distance of a track is calculated as 40 meters based on intervals between flags.<br /><br />10. Question 10 finds how many candies Tomo gives Marko to balance the number of candies between them, which is 4.<br /><br />11. Question 11 involves counting cubes, resulting in 12 white cubes.<br /><br />12. Question 12 analyzes dates, selecting May 15, 2015, due to the numerical similarities.<br /><br />13. Question 13 determines that the question mark is replaced by the number 5.<br /><br />14. In Question 14, leftover pizza slices are calculated to be 2.<br /><br />15. Question 15 discusses how a figure cannot be built with the given bricks.<br /><br />16. Question 16 describes drawing a missing puzzle piece by analyzing star arrangements.<br /><br />17. Question 17 calculates the number of paths Jake the Kangaroo can take, arriving at 6.<br /><br />18. For Question 18, the number of pirates climbing a rope is 15.<br /><br />19.
