There are three blocks. Lets call them A, B and C. Block A contains a medium black square. Then, we have block B with a medium black square in it. Block C is to the right of block B and below block A. It contains two medium black squares. Medium black square number one is touching the bottom edge of this block. Below a medium blue square there is medium black square number two. Below medium black square number two is medium black square number one. It is below the medium blue square.
Are all medium black squares which are below a medium blue square above the medium black square which is in block A?
