There are three blocks. We call them A, B and C. Block C is to the left of block B and to the right of block A. Block A has a medium blue square. Block B contains one medium blue square. There is also one medium black square in this block. The medium blue square is below the medium black square. And block C contains a medium yellow square. The medium yellow square is below a medium black square.
Is there any medium squares that are to the right of a blue square to the left of a medium black square?
