We have three blocks. Lets call them A, B and C. There are a medium black square, one medium yellow square and one medium blue square in block A. The medium black square is touching the bottom edge of this block. It is below the medium yellow square and the medium blue square. The medium yellow square is below the medium blue square. To the right of block A is block B. It has a medium yellow square. To the left of block B there is block C which contains a medium black square.
Is there any medium black squares to the left of a medium yellow square?
