We have three blocks. We call them A, B and C. Block C is above A and block B is below C. Block A contains a medium blue square. Block B has a medium yellow square. And block C contains two medium yellow squares. One medium black square is also in this block. Medium yellow square number one is touching the bottom edge of this block. Medium yellow square number two is below the medium black square. Below medium yellow square number two and the medium black square there is medium yellow square number one.
Are all medium yellow squares touching the medium blue square?
