If Q is in group 1 and S is in group 3, which one of the following CANNOT be true?

Why can't G,K be in group 2?

I don't understand how group 2 cannot have two children in this question. We even stated in question 8 that it is possible while still having Q in group 1 and S in group 3, so how could this be false?

I have the exact same question. Even after she flipped TH and FJ, group 2 still has GK as two children. How is that cannot be true?

Because D says "exactly 1 child in group 2" which cannot be true because after she flipped it 2 children, G and K, are in group 2. That's how I understood it at least.
