Final answer:
The outcomes of spending more time in day care cannot be determined by the statements provided, as children's development is influenced by a myriad variables including the quality of day care and family dynamics.
Step-by-step explanation:
Which of the following statements about children who spend more time in day care is true? The potential effects on children when spending more time in day care are complex and not encapsulated by the options provided. Direct research linking day care to these specific outcomes is nuanced, and other factors such as parenting style, the quality of the day care, and the socio-emotional environment play significant roles in child development. Therefore, none of the provided options (A, B, C, D) can be deemed categorically true without further context or clarification on the research findings they might be based on. It's essential to consider the individual circumstances and qualities of the day care environment to understand its impact on children's development.
