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