We have three blocks, A, B and C. Block A has one medium black square. Then, there is block B. It has one medium blue square. A medium black square is below the medium blue square. Finally, to the left of block A we have block C. It is above block B. It has two medium black squares. Medium black square number one is touching the bottom edge of this block. Below a medium blue square is medium black square number two. Below the medium blue square and medium black square number two is medium black square number one.
Is there a black thing which is below a medium square below all medium black squares that are below a medium square?
