We have two blocks. We call them A and B. Two medium yellow squares are in block A. Medium yellow square number one is touching the bottom edge of this block. It is below medium yellow square number two and a medium blue square. The medium blue square is below medium yellow square number two and a medium black square. Below medium yellow square number two is the medium black square. Above block A there is block B with one medium yellow square and one medium black square in it. The medium yellow square is below the medium black square.
Is there a medium black square touching all medium yellow squares that are below a yellow square?
