In general, boys are taller than girls at the same age. Therefore, we would expect the 8-year-old boy to be taller than the 8-year-old girl. However, girls tend to have growth spurts earlier than boys, which means that by age 10, the girl would likely have caught up in height or even surpassed the boy's height. Therefore, we would expect the 10-year-old girl to be taller than the 10-year-old boy.
