  • Three brothers, two sisters each. Count carefully.

    GPT-4o mini: Sally has no sisters. She is the only girl in her family, as the problem states that she has 3 brothers and they each have 2 sisters, which refers to Sally herself. Therefore, the number of sisters Sally has is 0.

    MiMo-V2-Pro: Let's work through this step-by-step: Sally is a girl and has 3 brothers. Each of those brothers has 2 sisters. Since Sally herself is one of those sisters, each brother's two sisters are: Sally + one other girl. That means there are 2 girls in the family total. Sally has 1 sister.
