Which One of the Following Is the Most Accurate Statement

Which one of the following is the most accurate statement about cultural differences among students?

A) When we have knowledge about typical cultural differences,we have a very good idea of how individual students are likely to perform academically.
B) We can make fairly accurate predictions about individual students' classroom behaviors when we know their ethnic background,but only when we also know their gender.
C) Children who have mixed cultural heritages (e.g.,those who have one Hispanic parent and one European American parent) almost always align themselves more closely with the "minority" culture.
D) Behaviors for two different cultural groups may differ on average,but variability within each group keeps us from predicting the behavior of specific individuals.
