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