Question

The contribution of environmental factors to racial gaps in intelligence scores is indicated by?

1) evidence that individual differences within a race are much greater than differences between races.
2) evidence that white and black infants score equally well on certain measures of infant intelligence.
3) the fact that Asian students outperform North American students on math achievement and aptitude tests.
4) all of the above.

Answer 1

Environmental factors contribute to racial gaps in intelligence scores, as indicated by individual differences within a race, equal performance of white and black infants on certain measures of infant intelligence, and the higher math achievement of Asian students compared to North American students.

Step-by-step explanation:

The contribution of environmental factors to racial gaps in intelligence scores is indicated by all of the above options:

1. evidence that individual differences within a race are much greater than differences between races
2. evidence that white and black infants score equally well on certain measures of infant intelligence
3. the fact that Asian students outperform North American students on math achievement and aptitude tests

These examples demonstrate that environmental factors, such as access to education, socioeconomic status, and cultural influences, can play a significant role in explaining racial gaps in intelligence scores.
