We have three blocks. Lets call them A, B and C. Block A has two medium yellow squares. Medium yellow square number one is below a medium black square and medium yellow square number two. One medium blue square is also touching the bottom edge of this block. The medium blue square is below medium yellow square number two and medium yellow square number one. The medium black square is below medium yellow square number two. To the right of block A there is block B which has one medium black square. Finally, we have block C which is above block A. It contains a medium yellow square.
Are all yellow things that are below a medium square below the black square that is below a medium square that is in block C?
