Learning gender-typed behavior is particularly easy for children when

A) they are exposed to adults other than their parents.
B) they have siblings.
C) parents set up gender-differentiated environments (e.g., bedrooms) .
D) their parents are divorced.

When parents set up gender-differentiated environments, such as decorating their child's room in gender-specific colors or providing toys and clothes that are gender-specific, it reinforces gender-typed behavior and makes it easier for children to learn and internalize these gender norms. Exposure to adults other than their parents and having siblings may also play a role in shaping gender-typed behavior, but not as significantly as parental influence through environment and modeling. Divorce does not necessarily have a direct impact on gender-typed behavior.
