One of the arguments against inherited racial differences in intelligence is based on data that shows: (Points: 5)

a college education reduces the gap between the IQ scores of white and black races.
nutrition reduces the gap.
scores for black test takers improve as they mature.
white test takers plateau at about thirty-five-years of age.

Assuming the first question is A, I pick A.

There is good data on the effects of nutrition (and disease control).

However, college education is a big leveler: http://wupa.wustl.edu/record_archive/1997/11-06-97/7682.html

To understand this argument against inherited racial differences in intelligence, we need to carefully analyze each point and explain the evidence behind them:

1. "A college education reduces the gap between the IQ scores of white and black races":
This suggests that when individuals from both white and black races receive a college education, the disparity in IQ scores between the two races narrows. This data implies that environmental factors, such as access to education and opportunities for intellectual growth, play a significant role in IQ differences, rather than solely being linked to genetic factors.

2. "Nutrition reduces the gap":
This point suggests that providing improved nutrition to individuals from both white and black races can help reduce the gap in IQ scores. Adequate nutrition is essential for brain development and functioning, and studies have shown that individuals with proper nutrition tend to perform better on cognitive tests. Therefore, addressing nutritional deficiencies can potentially mitigate any disparities in intelligence between racial groups.

3. "Scores for black test takers improve as they mature":
This statement implies that as black test takers grow older, their performance on intelligence tests improves. This observation suggests that intelligence may be influenced by factors other than genetics, such as educational and life experiences, which accumulate over time. It indicates that intelligence is not solely determined by innate abilities but can be enhanced through exposure to various learning opportunities and life situations.

4. "White test takers plateau at about thirty-five years of age":
This point suggests that after reaching a certain age (around thirty-five years), the IQ scores of white test takers tend to plateau, indicating limited improvement. This observation implies that there may be certain cognitive developmental milestones or limits that are reached by this age, after which individual differences in intelligence become relatively stable. However, it is important to note that this statement may not necessarily reflect an inherent limitation in white individuals' intelligence, but rather it could be influenced by various external factors, such as educational attainment or socioeconomic circumstances.

Overall, these arguments propose that environmental factors and life experiences, such as education, nutrition, and maturation, play significant roles in bridging the gap in IQ scores between different racial groups. They suggest that intelligence disparities may not be solely attributable to inherited racial differences, but also influenced by external factors that can be addressed and improved.
