Question 22
Which original figure A–E does not have exactly one quarter of its area shaded? Use the explicit diagram assumptions in the note below; the source artwork alone does not specify all needed dimensions.

Missing source dimensions: for this repaired exercise, assume A’s inner disk has half the area of its outer disk; its marked sectors are quarters. In B the marked internal points are midpoints, in C all grid cells are equal squares, in D the four bands have equal heights, and E is a square with diagonals. The artwork is not to scale. Without these assumptions, a unique answer cannot be justified from the source alone.
