We have two blocks, called AAA and BBB. Block AAA has a medium blue square and covers a medium yellow square. The medium blue square is over the medium yellow square. Above block AAA is block BBB. Block AAA is behind and near to this block. A medium blue square touches a medium black thing and is above another medium blue square. Medium blue square number one is inside block BBB. The medium black thing is within block BBB. Medium blue square number two is covered by block BBB.
Are all medium blue squares behind all medium blue squares?
