All of the choices are factors that contribute to the differences in IQ scores among racial groups. Cultural biases on IQ tests like the Wechslers can make it difficult for individuals from certain cultural backgrounds to perform well on these tests, which can result in lower scores. Additionally, family environment can play a significant role in shaping a child's cognitive development, and different racial groups may have varying experiences with poverty or lack of access to resources that can impact their IQ scores. Finally, educational opportunities and cultural values regarding cognitive skills can influence how different racial groups perform on IQ tests. Therefore, all of these factors should be taken into account when considering the IQ scores of different ethnic groups, rather than assuming that the scores are solely determined by genetic factors.
