A 6-foot tree casts an 8-foot shadow. A nearby tree casts a 36-foot shadow under the same sunlight on level ground. How tall is the second tree in feet?
AI reconstruction (instruction and added conditions): In each row and column, use each central-star style once: solid green, solid pink and pink outline. Independently, use each of the three surrounding green-and-pink frame designs once. Do not rotate or recolour the frame designs. Choose the missing figure.
AI reconstruction. Count colors, without using exact dot locations. Reconstruct the rule that every row contains the same total number of black dots and the same total number of outlined dots. Choose the missing cell.
AI reconstruction: Apply the same change from left to right in both rows: remove the four-point star while leaving every other shape unchanged. The arrow-shaped outline is only an answer frame.
AI reconstruction: The picture shows XXC. This is not standard modern Roman-numeral spelling. For this exercise only, read the two X symbols as a group of 20 subtracted from the following C=100. What number does that stated rule produce?
AI reconstruction. Use this rule for both pairs: the bottom shape turns 90° and becomes the outer shape; the small inner shape turns 180° and becomes the middle shape; the upper outer shape becomes the small central shape. Keep each shape’s colour. Choose the result.
AI reconstruction. Choose the piece that makes the incomplete grid on the left identical to the full grid on the right. Do not rotate or reflect the piece.
AI reconstruction: Choose the missing group. Added rule: To form the next matrix row, move each group one column to the left, wrapping the leftmost group to the right. Also move the first symbol in every group to its end, keeping colors unchanged.
AI reconstruction: Apply the top-row transformation to the lower-left figure: keep all boundary lines fixed and exchange black and white in every enclosed region. Which option is the result?
AI reconstruction. Complete a flat 4-by-4 slab, one cube thick. Added conditions: the top two rows must be red and the bottom two rows purple; retain all shown cubes. Which four-cube patch fills the gaps in the shown orientation?
