Q20. C Rule 1 = the dots move to one side in a clockwise motion.
Rule 2 = every other figure
in the sequence contains a black square in the corner of the whole box. This square moves
one corner clockwise. Figure A can be ruled out because the figure does not contain a black
square in the bottom right corner. Figure B can be ruled out because the dots are not in the
correct position. They need to be positioned so that the side that is empty and in between
the two lines of dots is at the bottom. The black square should be in the bottom right corner,
not the bottom left. Figure D can be ruled out because the side that is empty and in between
the two lines of dots should be at the bottom, not at the top right side. The black square
should be in the bottom right corner, not the top right. Figure E can be ruled out because the
side that is empty and in between the two lines of dots, should be bottom centre, not
bottom left. The figure also needs to contain a black square in the bottom right corner. 7
