We have three blocks, called AAA, BBB and CCC. Block AAA covers block CCC. Block CCC has a medium yellow triangle and covers a medium yellow circle. A medium black triangle and a small blue circle are covered by this block. A big yellow triangle is in block CCC. Near to the medium yellow circle there is the medium yellow triangle. The small blue circle is below the big yellow triangle.
Does block AAA contain all medium black triangles?
