We have three blocks. We call them A, B and C. There is a medium blue square in block A. This block also has a medium black square. The medium blue square is below the medium black square. Then, there is block B. It contains one medium black square. Block C is to the right of block B and below block A. It has two medium blue squares. Medium blue square number one is touching the bottom edge of this block. One medium yellow square is also in this block. This object is below medium blue square number two. Below the medium yellow square and medium blue square number two there is medium blue square number one.
Is there a medium black square to the left of all medium blue squares that are below a blue square?
