Question 1
A 5×5 paper is folded at row 1 (top over), then folded at column 3 (left side over). A hole is punched through all layers. When unfolded, which pattern shows the resulting holes?
With offset folds, the hole positions are mirrored asymmetrically. The hole at position (4,3) on the folded paper creates multiple mirrored copies when unfolded.
