There are three blocks. We call them A, B and C. Blocks B and C are below A. Block A contains a medium black square. Block B has a medium black square. And block C has two medium yellow squares. Medium yellow square number one is touching the bottom edge of this block. Medium yellow square number two is below a medium blue square.. Below the medium blue square and medium yellow square number two there is medium yellow square number one.
Is there a medium yellow square which is below a black square below all medium objects that are below a blue thing?
