There are three blocks, A, B and C. Block A has a medium yellow square. A medium blue square is touching the bottom edge of this block. It is below the medium yellow square. Above block A we have block B with one medium blue square and a medium black square in it. The medium blue square is below the medium black square. Finally, there is block C below block A. It has one medium black square.
Is there a medium square which is below a medium square below the thing that is touching the bottom edge of a block?
