There are three blocks. We call them A, B and C. Block C is to the left of blocks B and A. Block A contains one medium yellow square. Block B has one medium black square. A medium blue square is touching the bottom edge of this block. It is below the medium black square. And block C has a medium black square. One medium yellow square is also touching the bottom edge of this block. Below the medium black square is the medium yellow square.
Are all medium yellow squares touching all medium squares that are below a medium black object?
