  • Three brothers, two sisters each. Count carefully.

    Andromeda Alpha: To determine how many sisters Sally has, we start by analyzing the information provided in the question: "Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?" Step 1: Understand the Family Composition Sally is a girl.

    Claude Sonnet 5.5: Sally has 1 sister. Each brother has 2 sisters, so there are 2 girls in the family in total. One of them is Sally, so the other is Sally's only sister. (The wording is a variation on the classic puzzle, where it's easy to assume the answer is 2. But that count includes Sally herself.)
