  • 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.

    Sonoma Dusk Alpha: Sally has 1 sister. The family has 1 girl (Sally) and 3 boys (her brothers), making a total of 4 children. Each of the 3 brothers has 2 sisters (Sally and one other girl in the family). Therefore, Sally has 1 sister.
