Jacob has a group of hats. He decides to sort them by shape. Which sorting is correct?

This picture shows Jacob’s group of hats. And we know that Jacob wanted to sort them by shape. Some of Jacob’s hats are top hats. The top part of these hats is quite tall. Some of Jacob’s hats have a wide brim. Some of Jacob’s hats have a wide brim and a dome-shaped hat. And some of Jacob’s hats are caps. Jacob has tried to sort his hats three times. Each picture shows one of Jacob’s attempts to sort his hats. Did he get it right? In which of the three pictures has Jacob sorted the hats correctly?

In the first picture, the hats in the first column are all different shapes. There’s a top hat, a wide-brimmed hat, and a cap. The hats in the second column, or group two, have also not been sorted correctly by shape. We have a top hat and two wide-brimmed hats. The hats in group three, or column three, are also different shapes. There’s a top hat and two caps. So, the sorting isn’t correct in the first picture.

Let’s look at the second picture. In the first group, or the first column, all of the hats are the same shape. They’re all top hats. All of the hats in group two are wide-brimmed hats, and they’re all shaped the same. And the hats in group three are all caps. The hats in the second picture have all been correctly sorted by shape. The sorting is correct in the second picture.
