Click the green flag and follow the instructions.
Thanks for this Getting Unstuck 2020 challenge. I used variables and in the process got a little insight into the coding behind ActivInspires' containers. This was a hard one to setup. It is a little slow and sometimes glitchy but if you hit the green flag it should work! Try dropping the non-circles (incorrect answers) to see what happens. Thanks to scratcher MrQuentin for letting me know about make draggable in sensing!
