We have three blocks. We call them A, B and C. Block B is to the left of C and block A is above B. Block A contains a medium black square. Block B contains a medium black square and a medium blue square. The medium black square is below the medium blue square. Block C has a medium black square. Below a medium yellow square is the medium black square.
Are all medium squares which are above a medium square near to all medium squares which are below a medium square?
