According to one study, the heritability of IQ score in humans has a value of 0.52. What does this tell us about the role of "nature" vs. "nurture" in determining intelligence in humans?
A) Intelligence is a qualitative trait, affected by both genetics and the environment, and it can't be predicted by heritability scores.
B) Children of highly intelligent parents will likely be very intelligent, regardless of the environment in which they're raised.
C) There is an approximately equal chance that children of intelligent parents will be as intelligent as their parents, depending on the environment in which they're raised.
D) High heritability values don't mean that the intelligence of children can be accurately predicted because the environment plays a strong role.

A heritability score of 0.52 means that about half of the variation in IQ scores can be attributed to genetic differences, but the other half is likely due to environmental factors. This suggests that while genetics do play a role in determining intelligence, the environment also has a strong influence and cannot be ignored. Therefore, high heritability values don't mean that the intelligence of children can be accurately predicted because the environment plays a strong role.
