We have three blocks. Lets call them A, B and C. Block A contains one medium black square. Below the medium black square is a medium yellow square. Block B is below block A. It contains two medium black squares. Below medium black square number two and a medium blue square there is medium black square number one. Medium black square number two is below the medium blue square. Below block A there is block C. It contains one medium yellow square.
Is there a medium thing that is below a medium blue square above all black objects which are below a medium blue square?
