Final answer:
Sam is likely to have more brain development due to a stimulating environment rich in interaction and resources, which encourages the formation of neural connections, in contrast to Suzanne's less stimulating surroundings.
Step-by-step explanation:
You asked which of the following best describes a likely difference in brain development between Sam, who has a stimulating environment with lots of siblings and toys, and Suzanne, who has fewer toys and less stimulating surroundings. The best answer is (d) Sam is likely to have more brain development due to a stimulating environment. According to sociologist Annette Lareau's research, children from higher-income families often experience more active and targeted socialization that fosters their talents, skills, and problem-solving abilities. This type of environment, rich in stimuli and social interaction, tends to encourage the development of neural connections in a child's brain. Conversely, children from less affluent backgrounds may have less access to such stimulating environments, potentially affecting their cognitive and brain development.
