Most Eye Tests are a test of perceived alignment between two images.
In this Eye Test, the challenge is to perceive the difference between many images and put them in a logical order. In this case, the requested order is an order that makes sense according to the idea of Pilates.
This is meant to be a teaching test. Sure, you can subscribe and see the order suggested, but if you are $20 short of a year long subscription you can make suggestions or ask questions here and see if others (including me) can help you pass the test.
You can see the test here.
