I need an alternative explanation

I don’t get this explanation. I feel like it should be more simplified.

Hi, let's see what we know if F is in 1, and F is always with J.

1 F J
2
3

Since we know that F and J are kids, the final one in 1 must be an adult. We also know that since H is not in 2 and cannot be in 1 since H is a kid, H is in 3

1 F J
2
3 H

We also now know R is not in 3. This formation enables us to eliminate B, C, and E. Finally we can eliminate A, since G H and K are all children.
