We have three blocks. Lets call them A, B and C. Block A contains a medium yellow square. To the right of block A we have block B with two medium black squares in it. Medium black square number one is below medium black square number two. To the right of block B there is block C. It has two medium black squares. Below medium black square number two there is medium black square number one.
Are all medium black squares number two, above a medium black square number one?
