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