I need an alternative explanation

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.
