Children’s heightened sensitivity to physical differences in people significantly increases between the ages of __________, a time when attitudes toward race and ethnicity are being formed.

A. 2 and 3

B. 3 and 5

C. 4 and 6

D. 5 and 7

I think B

Based on my limited experience, I think you're right.

To determine the correct answer, we need to understand the age range during which children's sensitivity to physical differences increases and attitudes toward race and ethnicity are formed.

One way to find the answer is by referring to research or studies conducted on child development and attitudes towards race. These studies often use surveys, observations, or interviews to gather data from a large sample of children across different age ranges.

Another useful resource is developmental psychology textbooks or scholarly articles that discuss the stages of child development and the formation of attitudes towards race and ethnicity. These sources usually summarize the findings of relevant research studies.

Finally, you can consult child development experts or psychologists who specialize in this area. They can provide expert opinions based on their research or professional experience.

Considering the given age ranges, we can now evaluate the options:

A. 2 and 3: This range may be too early for a significant increase in sensitivity to physical differences and the formation of attitudes towards race and ethnicity.

B. 3 and 5: This age range aligns with the period when children start becoming more aware of physical differences and forming attitudes towards race and ethnicity. As a result, this could be a possible answer.

C. 4 and 6: This range overlaps with the previous option, but it might be slightly later for forming attitudes towards race and ethnicity.

D. 5 and 7: This range may be too late for the significant increase in sensitivity and the formation of attitudes towards race and ethnicity.

Based on the information provided, option B (3 and 5) seems the most plausible answer. However, it is always advisable to consult reliable sources or experts to confirm the accuracy of such claims.
