In Werner's Kauai study, by the time the children were 10 years old, those who had encountered prenatal and birth problems were:

A. more likely than other children to be impaired only if they also encountered environmental challenges.
B. at a consistent disadvantage to other children regardless of their environment.
C. demonstrating greater resiliency than other children.
D. nearly as advanced in language and motor skills as other children.

Children in Werner's Kauai study who had prenatal and birth problems were more likely to be impaired only if they encountered environmental challenges by the age of 10. This shows the significant role environment plays in child development.

Explanation:

In Werner's Kauai study, by the time the children were 10 years old, those who had encountered prenatal and birth problems were more likely than other children to be impaired only if they also encountered environmental challenges. This study emphasized the importance of environment in a child's development, highlighting that prenatal and birth problems alone do not necessarily lead to impairments. It illustrated that these impairments are more likely to manifest when combined with challenging environmental factors, such as inadequate caregiving or poor socio-economic conditions.
