We have three blocks. We call them A, B and C. Block A contains a medium blue square. A medium black square is touching the bottom edge of this block. It is below the medium blue square. Block B is below block A. It contains a medium blue square. There is also one medium yellow square touching the bottom edge of this block. The medium yellow square is below the medium blue square. Finally, there is block C above block B. It has a medium black square.
Is there a medium black square that is in block C to the left of a black thing which is below a medium square?
