question 91

Multiple Choice

For a long time, the fact that immigrants from Eastern Europe, Asia, and Latin America tended to be shorter than native-born Americans was taken as evidence that there were inherent racial differences between these populations.

What does this demonstrate?

• A) Race will always be an important way to understand physical traits.
• B) There are essential differences between racial populations.
• C) It is "natural" for different racial groups to avoid mixing.
• D) Some physical features, like blood type, are correlated with race.
• E) Racial differences are socially constructed and not genetic.
