We have three blocks. We call them A, B and C. Block A is below B. Block B is below C. Block A has a medium black square. Block B contains a medium blue square. And block C has a medium blue square, a medium black square and a medium yellow square. Below the medium yellow square there is the medium black square. The medium blue square is touching the bottom edge of this block. This shape is below the medium black square and the medium yellow square.
Is there a medium blue square that is above a black square below all medium squares that are above a medium black shape?
