Jeff and Dan are identical twins. Jeff was raised by their grandmother and Dan was raised by their aunt. Because of her age, the grandmother's interactions with Jeff were mostly sedentary as she spent a lot of time reading him books; in contrast the aunt interacted with Dan on a very physical level, showing him how to stack blocks, climb stairs and crawl. Based on the research findings of Arnold Gesell, what would you conclude about the twins' motor skills?

DArnold Gesell's research suggests that while environment can influence the rate at which children reach developmental milestones, the ultimate acquisition of skills such as motor and verbal abilities is largely determined by their biological maturation process. Therefore, while Dan's physically interactive environment might give him a temporary edge in motor skills, and Jeff's sedentary, book-focused upbringing might enhance his verbal abilities early on, the long-term differences in their motor skills would be negligible (B), acknowledging the influence of their environments on different skill sets (D).
