Question 20
Which option continues the sequence?
AI reconstruction: repeatedly move the leftmost block to the right, overlapping each of the other blocks in turn. At every overlap, draw the shorter block in front, so its top boundary remains visible. One frame shows each overlap, followed by a frame where the moving block has cleared them and is at the far right. Then repeat with the new leftmost block. Keep all block heights and widths unchanged.
