We have three blocks. We call them A, B and C. One medium blue square and a medium black square are in block A. The medium blue square is below the medium black square. Block B is to the right of block A. It contains one medium yellow square. Finally, we have block C above block B. It contains a medium black square. A medium yellow square is also in this block. The medium black square is below the medium yellow square.
Are all medium squares that are to the left of a yellow square to the right of a medium black square?
