We have three blocks, A, B and C. One medium yellow square is in block A. To the left of block A is block B which has one medium black square, one medium blue square and one medium yellow square. The medium black square is below the medium yellow square and the medium blue square. Below the medium yellow square is the medium blue square. Finally, we have block C. It is to the left of block B. It has one medium blue square.
Is there a medium square that is above a medium square above all medium squares which are below a medium square?
