We have three blocks. We call them A, B and C. A medium blue square is in block A. Then, there is block B. It contains two medium black squares. Below medium black square number two is medium black square number one. It is below a medium yellow square which is below medium black square number two. Block C is below block B and to the right of block A. It contains a medium yellow square.
Is there any medium yellow squares below the black thing which is above a medium square that is in block B?
