Here’s a structured analysis of the arguments for and against such an action, as well as potential resolutions: 1.

  • Three brothers, two sisters each. Count carefully.

    Kimi Linear 48B A3B Instruct: Sally has 2 sisters. Here's the reasoning: Sally is one of the sisters. Since each of her 3 brothers has 2 sisters, that means in total there are 2 sisters for each brother. Since Sally is one of them, the other sister must be another girl.
