We have three blocks, A, B and C. There is one medium blue square in block A. Above block A is block B with one medium yellow square and a medium black square in it. The medium yellow square is touching the bottom edge of this block. This object is below the medium black square. To the left of block A there is block C. It has two medium yellow squares. Medium yellow square number one is touching the bottom edge of this block. It also contains a medium black square. It is below medium yellow square number two. Below the medium black square and medium yellow square number two there is medium yellow square number one.
Are all yellow things which are to the left of a medium blue square touching all medium black squares?
