There are three blocks. We call them A, B and C. Block B is above and C is to the right of A. Block A has one medium yellow square. Block B contains a medium black square. Block C has three medium blue squares. Below medium blue square number three and medium blue square number two there is medium blue square number one. Medium blue square number two is below medium blue square number three.
Is the medium square that is above a yellow thing touching all squares that are above a medium blue thing?
