We have two blocks, A and B. Block A contains one medium yellow square. Above block A is block B with two medium black squares in it. Medium black square number one is touching the bottom edge of this block. This block also has a medium yellow square and a medium blue square. Below the medium blue square and medium black square number two is medium black square number one. The medium yellow square is below the medium blue square and medium black square number two. Below medium black square number two is the medium blue square.
Is there any medium yellow squares below the medium black square which is below a medium square?
