San Antonio's Study of Children from Two Neighboring but Vastly

San Antonio's study of children from two neighboring but vastly different communities in the rural northeastern United States revealed:

A) that those who received high-quality child care benefited in many ways and had fewer aggressive behavior problems than did children who received lesser-quality care.
B) that the values and beliefs of communities are expressed in children's language and social interactions.
C) that higher level of cortisol was associated with poorer executive functioning in children in daycare.
D) that the children in a family child-care setting ranged widely in age.
