?Prompt
Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?
Response
Sally has one sister.
Reasoning
- Sally herself is a girl.
- She has 3 brothers.
- Each brother is said to have 2 sisters.
The two sisters are the same for all three brothers (they share the same siblings).
Thus the total number of sisters in the family is 2. One of those sisters is Sally, leaving one other sister for her. So Sally has one sister.
