  • Three brothers, two sisters each. Count carefully.

    Nemotron 3.5 Lightning: Sally has 2 sisters. Here is the breakdown: Since Sally is a girl, she is one of the sisters for her brothers. Each brother has 2 sisters. Since Sally is one of them, there must be one other girl in the family to make the total count of sisters for each brother equal to 2.

    TNG R1T Chimera: Sally has 3 brothers. Each brother has 2 sisters. Since Sally is one of the sisters, there must be one more sister to make the total number of sisters each brother has equal to 2. Therefore, Sally has 1 sister. [ \boxed{1} ]
