Question 2

AI reconstruction: The written question was missing. Choose the tile that fills the square marked ? so that the surrounding lines and repeated shapes continue smoothly. Use each option in the orientation shown, without rotating or reflecting it.

Question 4

AI reconstruction: The written instruction was missing. The small gray figure is the complete reference. Choose the missing red section that makes the large outline an enlarged copy of that reference. The dotted diagonal separates the given and missing regions; it is not a mirror axis. Keep the grid spacing and all existing red lines unchanged.

Question 9

AI reconstruction. Added condition: compare the complete outer silhouette of the butterfly together with the flower and leaves, in the same orientation. Ignore colours and internal lines. Which option has the matching outline?

Question 11

AI reconstruction. Each large group is followed by a compact version with the same four positions. Reconstruct the overlap rule by placing discs in order top-left, top-right, bottom-left, bottom-right; each later disc is in front of earlier discs. Choose the compact form for the final group.

Question 14

AI reconstruction (instruction and any added conditions): Choose the piece that fills the white gap and continues the surrounding picture. Keep the piece upright; do not rotate or reflect it. Compare the picture at the boundary, not just the shape of the gap.

Question 15

AI-reconstructed instructions: Complete the covered part of the picture by continuing the visible lines, colors and repeated shapes. Keep each piece upright; do not rotate or reflect it. Compare the positions of the boundaries, allowing only small printing irregularities. Choose the matching piece.

Question 18

AI reconstruction: Added task for this reconstruction: use the large diagram as a color-position model. Choose the four-wing figure whose two upper triangular wings have the upper half’s color and whose two lower wings have the lower half’s color. This is a color-matching task; no folding operation is specified.
