?Prompt
Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?
Response
Sally has 1 sister.
Explanation
- Sally is a girl and has 3 brothers.
- Each brother has exactly 2 sisters.
- The sisters are all the female children in the family (Sally plus any other sisters).
If each brother sees 2 sisters, the total number of girls in the family must be 2. Since Sally is one of those girls, there must be exactly one other girl. Therefore, Sally has one sister.
