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