We have three blocks. Lets call them A, B and C. There is a medium blue square in block A. Then, there is block B. It contains a medium black square, a medium yellow square and a medium blue square. The medium black square is touching the bottom edge of this block. The medium yellow square is below the medium blue square. The medium black square is below the medium blue square. This object is below the medium yellow square. Above block B and to the right of block A there is block C. It has a medium black square.
Is there any medium blue squares above the medium black square that is below a blue square that is in block B?
