There are three blocks. We call them A, B and C. One medium yellow square is in block A. Block B is below block A. It has one medium blue square and one medium black square. Below the medium black square there is the medium blue square. Finally, we have block C. It is to the left of block A. It has two medium black squares. Medium black square number one is below medium black square number two.
Is there a medium square that is below a yellow shape below all medium black squares?
