There are three blocks. We call them A, B and C. Block B is to the left of A and block A is to the left of C. Block A has two medium black squares. Medium black square number one is touching the bottom edge of this block. It is below medium black square number two. Block B has one medium blue square. It also has a medium black square. Below the medium black square there is the medium blue square. And block C contains one medium black square.
Is the blue thing below any medium black squares?
