There are three blocks. We call them A, B and C. There is a medium black square in block A. Below the medium black square is a medium blue square. To the right of block A there is block B with one medium black square and a medium blue square in it. Below the medium blue square there is the medium black square. To the right of block B there is block C. It has a medium black square.
Is there any medium black squares below the blue square that is to the right of a medium black thing which is in block A?
