We have three blocks. We call them A, B and C. Block A contains two medium black squares. Below medium black square number two there is medium black square number one. Above block A is block B with a medium black square and a medium yellow square in it. The medium black square is below the medium yellow square. Above block B there is block C which has a medium blue square and a medium yellow square. The medium blue square is below the medium yellow square and a medium black square. Below the medium black square is the medium yellow square.
Are all medium things that are below a black square below all medium squares which are above a yellow square?
