We have three blocks, A, B and C. Block A has two medium blue squares. Medium blue square number one is below medium blue square number two. A medium black square is touching the bottom edge of this block. It is below medium blue square number two and medium blue square number one. Block B is below block A. It contains a medium yellow square. To the right of block B there is block C which has one medium blue square. It also contains a medium yellow square. The medium yellow square is below the medium blue square.
Is there any medium yellow squares below a medium square that is below a medium blue thing?
