We have three blocks, A, B and C. A medium black square is in block A. Then, we have block B. It has three medium black squares. Medium black square number one is below medium black square number two and medium black square number three. Medium black square number two is below medium black square number three. Block C is below both blocks A and B. It has a medium yellow square.
Is there a black object that is above medium square number one above all medium squares that are above a medium yellow square?
