We have three blocks. Lets call them A, B and C. A medium blue square and one medium yellow square are in block A. The medium blue square is below the medium yellow square. Then, there is block B which contains two medium blue squares. Medium blue square number one is touching the bottom edge of this block. It is below medium blue square number two. Block C is above blocks A and B. It contains a medium black square.
Is there any medium blue squares that are below a medium black square above the yellow thing?
