This is a 3 "thing" Venn Diagram.
There is a blue circle, a red circle and where they overlap purple.
With a visible 7 x 5 grid over the top.
Also a pile of 9 pictures.
3 of the pictures go into the frames over the blue circle [******], 3 of the pictures go into the frames over the red circle [******] and 3 of the pictures go into the frames over the purple area [******].
Drag 8 of the 9 pictures from the pile and drop them into the grid.
Do not bother about sorting at this stage as you can rearrange the position of the pictures at any time.
